Metal Detecting: Search with a metal detector, something for you? five wounds of Christ Metal detecting , an exciting hobby! Those who have never worked with a metal detector is difficult to imagine what is going is underground and where. Someone who agrees to go with a more experienced amateur metal detector will soon with big eyes watching what's become removed from the soil. WTF - OMG ALL ROMAN COINS !!! It's not just a little swaying back and forth with a metal detector and dig up the loot with a beep. It goes much further and how far it goes depends on you. Are you going to delve into the local history, compare old cards with new cards? Then you can go to places where nice finds in the ground in no time. No history lover? The beaches, meadows and fields are especially loved by amateur metal detector. What can you find with a metal detector? Depending on where one is looking for it derives from the Old Dutch soil buckles, coins, weights, buttons, coins, thimbles and all kinds of jewelry from the ground. Mantel pins, very old axes, daggers are some examples. You will be amazed by how much has been found. Even items that you will not recognize but still have a story. By letting determine (examined by experts) the object you come to know about the subject more. You'll find a lot of coins from all periods. This can vary from a 1 cent from 1920, for example, Celtic coins The objects can be of different metals such as gold, silver, bronze, tin, lead, brass, aluminum, iron. gold silver bronze tin Viking lead brass The objects may be contemporaneous, these often finds that one will find on a recreational area or beach, but are made finds of hundreds and hundreds of years old. Places where people for years and years living Finds of 1100 years BC is no exception. Sometimes, even so old that the object depending on the metal is difficult to recognize in the course of time. So it is not always. There are coins, weights, belt buckles, pins, jewelry, etc. to the top if they are not there yet but have a long dating back hundreds of years. Coin is that even to read. Now you might think: 'touches the bottom eventually anyway once empty? As long as the bottom anyway visited by someone with a metal detector and there is nothing more to be found? Absolutely not! For various reasons, and that will become clear later. Come up from the ground that are fun for their own collection but there are also finds up for an archaeologist, historian or museums have huge value. Then it is not always to the metal. It does not have to be. No gold There are even last series of silver coins (there were 25?) Found yet, packed together, total value € 10,000! Not because of the silver, but because of the unique historical value. Experienced people who use a metal detector and special finds have made up their findings sometimes (temporarily) available to a museum. Some museums buy them. Others sell their finds back to collectors. There are occasionally made special finds that are unique, so unique that it reaches the newspapers. sometimes it goes all over the world. Now that may sound as if the bottom is littered with all kinds of valuables. Metal detective is a fantastic hobby and everyone has their own interest in finding objects. There are people who specialize in the search for specific finds. Finds from certain periods in history (roman, Celtic, WWII). There are people who are searching the beach for lost jewelry and coins that people have lost the last summer days, there are people who search on military. These include personal belongings of soldiers from the first and especially the second world war. There are people who study old maps, books and end up in places where there used trade routes are located. On those routes have lost a lot of stuff, hiding from robbers or robbers who hide their loot temporarily but never return. They're still in the ground. Metal Detector Accessories ( WHAT DO YOU NEED ) When you get your first metal detector all of a sudden you realize you need other metal detecting accessories. You need a digger of some sort, ground cloth and a pouch to put the trash and treasures that you find in. You don't need to buy all of this stuff now, but something to think about. Here is a list and photos of the items we have used and continue to use while land or beach hunting. Digging Tools Get you a digging tool You need some sort of digging tool to dig with. We started out with just a basic garden trowel, and then graduated to a hunting knife that we bought at an Army Navy Store. Now days they have some pretty fancy digging tools. Some have a saw like action on one side for getting at tree roots, and even have markings on them in inches to let you know how deep you're digging. Ground Cloths Homemade ground cloth If you plan on digging dirt, then a ground cloth can be a very helpful item in recovering your target. Where do you get a ground cloth? Make one. We used a pair of old jeans cut them above the thigh and above the knee, then cut it along the seam. The jean material has proven to be very durable too, as you can see. We stapled on two pieces of wood to the cloth to make dumping the dirt easier, but make sure the staples are small enough that your detector doesn't detect them. ROMAN COINS Use a ground cloth Here's how you use it. When you cut a flap in the grass, and start scooping out dirt, plop it on your ground cloth that is laying close by. Then scan your dirt to see if you got the target, or if it's still in the hole. Once you locate the target, pick up your ground cloth carefully from the sides with the dirt still on it, and pour the dirt back into the hole, press the grass flap back down, and step on it to secure it. How simple! And you don't leave any telltale signs of you having been there either, no dirty grass! Once you start using one, it's hard to go without one. If you don't use one, your target will likely fall out of your dirt, and then you will have to locate it again in the surrounding grass or leaves. Pocket Probe Garrett Pocket Probe The only reason we have this Garrett probe is because we won it at a club hunt. It has come in handy especially in the woods, where you have to deal with a lot of roots. Also it's nice to use it in places where you don't want to dig a hole like on a well-manicured lawn. Just put the probe next to the ground to find the target, and then pop the coin out with a blunt edged screwdriver. It locates targets to several inches down, so you'll know exactly where to dig. There is a spot for headphones on it, like the small kind. But who wants to be switching headphones all the time. It runs on a 9 volt battery. Using the pocket probe It’s difficult to pinpoint items deep in the ground unless you have a hole big enough to fit it in. We tried it at the beach once, and got sand in the button you push to turn it on. It got stuck and we had to take it apart and clean it out. This unit makes a pretty loud sound, so it was strange using it when other people were around. It draws more attention to what you're doing. Whites Electronics sells an probe called a Bulls eye pin pointer. You can actually even use an item that construction workers use to find nails behind sheetrock, called a stud finder. Heavy Duty Beach Sand Scoop Dry Sand Scoop We bought this beach sand scoop on Ebay for $18.00. We like it and use it alot. It has held up pretty good no matter what we do to it. Carol likes the comfortable plastic grip on it, yet she still wears a glove on her hand to keep from getting a blister by the metal piece on top. We prefer these round holes in the scoop, versus the sand scoops that have square holes. We have two of these scoops now, one for me and one for her. Sifting in the sun set We originally started out with a dry sand scoop that had a 3 foot handle on it, but the handle bent. I cut the bent piece off but it is too heavy to use as a dry beach sand scoop so it's sitting in the storage. We tried making us a scoop out of a large grain scoop we got at a feed store by drilling some holes in it, but it didn't last very long. Also make sure the beach scoop you buy is stainless steel, not galvanized. Treasure Hunting Pouches treasure hunting pouches guess we need to say something here about what we've been using to put our trash and treasures in when we go out treasure hunting. We started out using a carpenter's 2 pocket pouch or apron. They are really cheap, just a couple bucks at the hardware store, and they tie around your waist. Then we kind of graduated to fanny packs, which seems to be our favorite choice because they zip up. Several times we've been fortunate enough to find some camouflage hunting pouches in the Sports Dept. at Walmart. Several times in the woods we have just used the pockets on our camouflage pants. Also, if we know we are going to a beach that is pretty well trashed, we take along some plastic grocery bags to drop the big trash and aluminum cans in to take out with us, then if you get stopped by cops or someone questions what you're doing, you can show them how much trash you picked up. They like that. Metal Detecting Headphones Maz Big Blues head phones Here's an item we forgot to mention. Headphones are a must! Sometimes when you buy a metal detector the dealer will throw a pair of headphones in with it, but sometimes not. If you ask, they just may do it. We've used all kinds of headphones, some are expensive, like the Jolly Roger made by Detector Pro. Whites also have exclusive headphones. But you can easily get some starter headphones at Radio Shack for about $15.00. Make sure they have volume control, and stereo would be nice. Our favorites headphones are called The Big Blues, made in England by Maz Detectors. The Big Blues are soundproof and well worth the 60 bucks. Flashlights or Headlamps Headlamps Once you get out to hunt and start finding good stuff, you're not going to want to leave once it starts getting dark, especially in the summer. So get yourself a headlamp and some flashlights. There are some small flashlights that you can clip on to your ballcap or shirt. They have some headlamps that are waterproof, like the larger one in the picture, but they tend to get heavy after a while. The smaller one is an LED headlamp and it shines a blue light, so you can't really see that good with it, but the batteries last a long time. It also has different blinks that you could use to signal your hunting buddy. Magnifying Glass or Loupe Lighted magnifying glass and loupe Besides all of the above, here's is some additional stuff you'll eventually need once you start finding stuff. First of all when you start locating those old coins, you got to have a magnifying glass or loupe to check it out. Any more magnified than that, and you won't be able to tell what it is that you found. Plastic Containers for Finds Assorted plastic containers Then after you check it out, you need some kind of containers to keep all your treasure finds in. These plastic containers here are used for fishing lures. The small gray container is double sided, and we take it with us on the hunts. These plastic containers come in all different sizes at Walmart and they are cheap, so go pick one out. We get a new one every year to keep our finds in. They have slots you can adjust to fit to the size of your finds. Batteries and Battery Charger Also, last but not least, keep a good supply of batteries with you. We started out using regular AA's and then invested in some Nickel Metal Hydride batteries from Radio Shack and a battery charger. They lasted us a couple of years, and now were back to using Energizers AA's again. You can get a 30 pack at Home Depot for $15.00. There's nothing worse than getting all the way out to the field and having your batteries die. Getting The Most From ( Online Map ) Researching where to dig. Research is the single most significant aspect to being a success full treasure finder !!!!!!! ROMAN OIL LAMP One of the biggest challenges that most metal detectors come across is finding new locations to hunt. I myself do a fair amount of research, going over old maps, online recon, and a lot of foot work. Finding new places to hunt is not that hard, you just have to put all the pieces of the puzzle together. The World Wide Web, better known as the Internet, is changing the way we experience our treasure hunting. Being able to search for sites, from the comfort of our favorite chair. The old method we would spread out that old battered, coffee stained street map and look for schools, city parks that we haven’t hunted lately. The new and improved method involves sitting at the computer, viewing aerial photos, then zooming in to get a close-up look at potential sites. Many of these online mapping sites, allow you to view street level pictures from satellite images, so you can view possible sites and the landscape around the site, long before you head out to the location. Giving you the heads up, you can tell whether the layout is rocky, grassy, hilly, or wooded, and then find out how good it may be for treasure hunting. old maps good to use This aerial view technique is a handy tool, for metal detectorists, it can allow you to spot those vacant lots, forgotten hiking trails, old home sites, and property lines that you would otherwise miss. Google Maps is a great site for some up to date map data, and they are easy to use Do your research !!!!!!!!!! http://www.historicmapworks.com/ 1) Search for your town, choose desired map. 2) Select "Overlay This Map" , then click "Historic Earth Basic/Free" on right. 3) Navigate the map as you would on Google Maps, but control the transparency of the historic map with the Opacity toggle on right. 4) Toggle between the standard view, hybrid view, or Satellite photo view as needed. more to know……..About this great hobby For thousands of years, man has used metal objects and lost in the area now known as the Netherlands. The northern half of our country is rich find places, due to excavated mounds, and the southern half carries interesting traces of some four hundred years of Roman occupation. In itself is reason enough to look what the lost metal is left. But the post-Roman and Merovingian period is characterized by interesting metal objects, often funerary equipment, including beautifully decorated cloak pins, hair needles, rings, daggers etc.. Also from the late Middle Ages, many artefacts due to mutual scheming, robber barons, wars between small princes, dukes, bishops (!) Etcetera. Throughout the ages, we see the archaeological finds how the weapons evolve, through the crossbow, the musket, the musket, the blunderbuss and beyond. For the detector amateur fertile periods, the times were the major cities were preparing themselves as superpowers and wrested himself to the power of the aristocracy. That this was accompanied by violent clashes should be clear. Meanwhile, city manure (with many a lost coin) as compost over then sprinkled fields .... Each skirmish, every battle, the Eighty Years' War, the French occupation, and of course as a big win the Second World War have tons of material added to the soil archive. And modern man has still not unlearned; still come daily coins, buttons, rings, pendants, necklaces, earrings and bracelets in the soil, often in recreational places such as beaches and playgrounds. How GET all this metal in the soil ?????? Partly intentional: Roman and Merovingian grave goods and offerings. Fearing buried capital as coins, jewellery, silverware. Fearing burial equipment of a deserter. Partly by accident: Lost jewellery and money, lost weapons during battles off sliding rings while swimming, smashed chains while frolicking .. And then out of laziness: waste, munitions debris, projectiles. A good amateur detector is designed to work as much as possible, taking into account the above causes. Operation of the detector amateur. A seasoned amateur detector identifies what to expect, given the history of this area. Finds a ground for In addition, he tries to imagine how the loss of the metal objects can be. Gone exactly Example: A castle siege; where would the besieging army to save his camp? Outside of fire, within sight of the castle, possibly camouflaged by trees and rolling terrain. Another example: A burial of military equipment; which buries a soldier deserting his bags? Out of sight of everyone, often in wooded area, preferably with a tree easily recognizable or hill, to find if he changes his mind ... if that tree is still alive, his business, he is more than fifty years old and thus a fat boy! A skilled amateur can be also send by example shards or remnants of earthenware pipes in a field; pipes represent a great opportunity for old coins (bucks). This focused approach takes the experienced amateur many times more than the newcomer who haphazardly walking with his detector over the first best site to wave. The soil archive. All that is hidden in the soil is called the soil archive. For the archaeologist is where and how the object is more important than the object itself, because important conclusions can be drawn from. The detector amateur is more about collecting interesting and sometimes valuable items. Many official archaeologist thinks detector amateurs from the soil archive should stay away because so disturb the soil archive. But the amateur detector must have the already disturbed upper 30cm, where every year the team of farmers' Harms is going through, or ejected from the ground on a construction site. In any case it is not the detector amateur that the soil archive disrupts the contrary, without the amateur would be many objects remain undetected and thus lost forever along with the construction debris, or in the top layer of a field accelerated fall prey to corrosion by exposure to oxygen and eutrophication. Partly due to the work of the association detector DDA archaeology seems prepared to adjust his views on the detector amateur. The crowning glory of this association would be that the amateur is taken by the archaeology seriously and is activated as an information source for the archaeologist. A concentration of metal finds, after all, may be a reason for archaeology on site to do an extensive excavation and as read before it is swallowed up by residential areas, railways and highways. The soil archive The Amateur "Detector Amateur." For an amateur detector is very attractive to be a good association. He serves as the common interest, meet fellow amateurs on club days, may determine to his discoveries receives club magazines, enjoy discounts at some detector suppliers, and so on. An association that I decided to recommend to the DDA, partly because of the efforts that this organization is making to get the official archaeology. On good terms Their bi-monthly club magazine is worth gold for a detector amateur. Modern detection technique. All of the above musings would be fruitless if we do not have resources to detect. Actual metal in the soil Modern technology makes it possible to detect a coin. (Penny size) up to 30 cm depth with a lightweight detector A military helmet of up to 100 cm., So dig! There are many different detectors, with very different prices and features. It would be dumb luck, they then immediately chooses the most optimal from a layman. Our expertise is your choice much easier and safer. If you know a bit of what you want, then we have the best for you detector. CHOOSE THE Detector YOU WANT TO Buy (There is NO BEST metal detector.) That said, the best metal detector is the one you'll be able to use properly. Although it doesn't take a rocket scientist to operate a metal detector, in order to use one successfully, you should be absolutely sure you are going to buy it from a reputable dealer who has a showroom to demonstrate the products and does no shady deals in parking lots or parks. This is the only way to make sure you get the right machine for you and that you will have personal support whenever you need it. So let Big Valley Metal Detectors help you to choose the best metal detector to meet your personal needs and budget. After I got the above question numerous times I decided to add a 'Best Detectors' page as a guideline, which helps all who visit my site avoid mistakes in choices brought on by the voluminous amount of information and opinion on the internet. Yes, I have my opinions, but those are based on my experience as a detectors and a multi-line dealer. Below are general purpose metal detectors. There are many more, and if I have not mentioned the one you are interested in, it is not necessarily because it is no good. More than likely I just decided to keep this page from attaining a daunting length. Also, this is one of the last pages to be updated on a regular basis, as I spend more time with my customers in person, and the web really does come last. Just give me a call and I'll give you my honest assessment if you don't see what you are interested in.

At this price point, the F2 currently dominates the field. the Fisher F2 represents the BEST value in a metal detector under $300.00. The large digital numerical read out from 0 to 99 is unmatched in any metal detector under $500.00. In addition, the F2 has an on the fly 3 segment depth scale and a precise pinpoint depth reading. Even more impressive is the speed of target sampling which matches the Tesoro line-up. The ability of any metal detector to respond to targets as the search head is kept in motion over the ground is important for seeing desirable targets ‘hiding’ in the trash. Tesoro Compadre Comments: There is a good reason this is a popular selleR. The Compadre’s 12 kHz circuit will see the smallest fine jewellery deeper than almost any other metal detector on the market. And... it has the quickest target response on the market today thanks to its two filter circuit and 5.75” loop size. You can even use it for electronic prospecting since it’s sensitive to gold nuggets from match head size on up. It boasts excellent audio characteristics. While most other metal detectors play the guessing game as to trash vs. good targets, the Compadre, like the rest of the Tesoro line, has analogy audio with lightning fast target sampling. A target response that exhibits a smooth, continuous tone is one worth going after. Choppy, sputter or harsh audio responses are almost always trash. I am so confident in the Compadre’s ability to sniff out elusive gold rings, it remains one of my preferred choices in a rental for lost valuables. One knob operation and the industry’s strongest warranty (lifetime) makes it a formidable detector presence in the under $200.00 range. White’s Coinmaster and Coinmaster Pro Comments: great entry level machines. White's has nailed these machines, and they are a great for anyone exploring metal detecting as a hobby, but who does not wish to commit more than a few hundred dollars to start with. Garrett Ace 150 and 250 Comments: From 2004, the White’s Prizms dominated the lower end of the professional market. So Garrett Electronics came out with the Ace 250, which rivalled the White’s Prizm IV in terms of features and performance. The Ace 250 offers more sensitivity and better visual discrimination resolution than the $179 Ace 150. My only complaint is the size of the screen… a bit TOO small and hard on the eyes compared to the larger screens of the Coin master and Fisher series. Garrett Ace 350 Comments: prime in the Ace line-up is the Ace 350. And right now, there is a holiday pack for added value. Check it out!!! It features their 11" DD coil. A higher frequency and improved iron discrimination make this machine a real winner in the serious entry level class of machines. Price Range: $400 to $900 White's 5G Comments: A Prizm with ground balance along with the spider coil that comes stock with this nice machine. It makes all the difference! This metal detector is smooth, deep and hard to beat at this price point. The Prizms also enjoy compatibility with the Jimmy Sierra Bigfoot. White's Prizm T6 Comments: The Prizm T6 with advanced ground tracking, and so many features, you must see it to believe it. Part of the secret to the Prizm's effectiveness is it's ultra-smooth audio circuit and loud alert. In March 2009 the 4x6 shooter search coil was introduced. Customer response was very favourable, with reports of digging up dimes (smallest USA coin) at 9"! One of my favourites with the highest fun factor in the metal detecting industry in a detector under $700.00. Fisher F4 Comments: Fisher, acquired a few years back by First Texas, who during the year prior to that hired one of the industry's BEST engineers, Dave Johnson, has hit yet another homerun with the Fisher F4. Excellent visual discriminator, easy to read and lightning fast target sampling. Seems to have the same Hp as the F2 but with more bells and whistles to supplement an excellent circuit, including manual or auto position ground balance and an all metal mode with auto tune position for prospecting. Visual target ID scale adorns the top portion of the display with target pointer and large digital numbers. Comes with the F75 10" wide scan loop AND the 8" concentric for trashy areas. Gold bug Pro Comments: with this incarnation Fisher has hit a home run. This series can be used for coin shooting, relic hunting or gold prospecting, and is considered a crossover. Comes in various packages that include different accessories. Garrett GTP 1350 Comments: In 2004, the Garrett GTP 1350 came on the scene, replacing the GTAx 1250 and adding a sizing feature called target profiling, which placed the target into one of three size categories; A, B, C. The Garrett GTP 1350 has a well-balanced feel and is light enough for most folks. Digital tone, including Garrett's bell tone response. Full featured. Depth is above average, as well as Garrett's visual discrimination and electronic pinpointing. The rear battery compartment can pull off and hip mount, decreasing the weight on your arm. Garrett AT Pro waterproof Comments: this machine shows that Garrett is paying attention to customer demand. This is a machine you can submerse in water and then take it to hunt the highest mountain peaks. The available search modes include both standard and professional settings and the new 11"DD coil it ships with make this machine a huge breakthrough for technology at this price point. The connection sucks ; that’s only min point Minelab X-Terra series Comments: Since 2005. The X-Terra series have an extremely light feel and operate at a standard frequency of 7.5 kHz with an ultra-quiet digital circuit. My first time out with the X-Terra 50 and first target at A Beach was a white gold earring at about 7", easily heard with the X-Terra's loud alert target response and wonderful tone ID. The digital number display is about as easy as the Fisher F4's to read, although the X-Terras are not quite as quick as the Tesoros or Fishers on target sampling, The X-Terra 50/505, like the flagship X-Terra 70/705, can change frequency by changing the loops. The X-Terra 50/505 can switch to 18+ kHz loop for superior audio response on small gold targets and nuggets. X-Terra 50 has manual ground balance control while the 30's ground balance point has been preset by the factory to handle most conditions. The X-Terra 70 offers sophisticated automatic ground tracking and additional programming AND a 10" loop that changes the frequency to 3 kHz for outstanding target response on high conductive silver targets. The updated 305, 505 and 705 do have upgraded software, and react a little faster, generally speaking. Tesoro Vaquero Comments: Tesoro's Vaquero operates at just under 15 kHz with a 3 position frequency shifter to further avoid noisy cross talk from other detectorists or power lines. These are Umax detectors, which makes them about the lightest in their performance class. The Vaquero has a manual 3 3/4 ground balance, which works the all metal and discrimination mode. The Vaquero's circuit is also found in the Cibola, which has its ground balance point set internally by Tesoro. Tesoro's DeLeón, Cortés, & Tejón Comments: All three share Tesoro's lightning fast discriminator target sampling and lifetime warranty. The DeLeón and Cortés (top dog in Tesoro's line-up) have visual target ID, but the display is very small compared to other visual discriminators. The Cortés also has a feature similar to White's Signagraph system, but again, the visual lacks resolution, so dimes, quarters, halves, and dollars read as 'COINS'. Tesoro's real strong point as always been its analog audio response. Smooth targets that are coin size are always worth digging and broken and/or harsh sounding targets are worth avoiding. The Tesoro Tejón is Tesoro's deepest detector, operating at a 17.5 kHz. This is a bit on the high side for silver hunting, but reports from the field say that the Tejón is bringing in a lot of silver normally masked by trash targets and unseen by the competition. The Tejón uses a twin level discriminator that can be set in a variety of ways. I set the higher level to barely pop on a zinc penny so I don't have to dig them. Last time out with the Tejón, my associate dealer, Greg @ Trans Bay Metal Detectors, scored a beautiful white gold wedding band in the bark and it is one of my favorites. Because of its higher frequency, the Tejón is a bit more reactive over the small iron, but that can be a positive as far as seeing through the nails etc. The all metal modes on both the Vaquero and Tejón have a preset gain level, so the sensitivity is really a stability gain control in the discrimination mode. White's M6 and MXT Comments: one of my favourites with the highest fun factor in the metal detecting industry. With its 14.7 kHz frequency, and sharing the same horsepower as MXT, the M6 adds seven tones of target ID in addition to the highest visual resolution you can find in a metal detector, 190 segments. The MXT (now a Pro series model), considered by many as the BEST HYBRID for serious electronic prospecting, relic hunting or coin and jewellery hunting, offers additional features like separate programs that change the visual display. Its ground tracking system has been considered by many to be the best on the market. The 'Pro now has tone ID, a display backlight and a 'ground grab' button, to make it even easier to operate. My buddy Greg tested the prototype MXT with various prototype chips in cooperation with White's technical engineering staff. This culminated in a ground tracking system that set the standard from 2005 forward. In March 2009 the new 4x6 shooter search coil was introduced. Customer response has been very favourable, with reports of digging up dimes (smallest USA coin) at 9"! White's MXT continues to be one of the most popular sellers at Big Valley Metal Detectors because of its ability to tackle virtually every surf and turf situation. The only drawback is that it isn't fully submersible, like some of the specialty detectors. Price Range from about $1000.01 THE BEST IN DETECTOR LAND ; XP Deus 3 Comments: For the first time in a very long while, a truly innovative metal detector has come along. And now it is available with the 3.0 software. Sure, there have been new bells and whistles and beautiful make-overs on well-established technology, but this is a detector that seems to have a little more than the average great metal detector. After you have gotten over the shock of how light the whole unit is, how easy it was to charge the coil, control box and headphones simultaneously with 1 usb charging unit, and appreciated the fact that the set-up, including coil and headphones, is COMPLETELY WIRELESS, there is still plenty more to get excited about. This unit is FAST! Very fast. And the ground tracking is superior to ground tracking on other top detectors. The Deus features a new way of filtering out the iron, which does not involve discriminating out the things you do want to see. And that is just for starters. Treat yourself and come check out this ultimate metal detector! I actually have had this machine out quite a bit since I got it in, and my review of it very favourable. You can read some of it on my Facebook page (click on the icon at the top of the page). This machine is real sweet, and it may just change my mind about there being no best metal detector.... Here is the write-up that is on my "Great Finds" page: This is a 1944 British Half Crown I dug today. The yard from which I dug this and other things (coins, tokens etc.) belongs to the neighbour of a friend of mine who owns several of the top machines out there, and he has hunted it for the last few decades. He has been on that nice old property many times with his detectors, and was stunned when he saw what I pulled out with the Deus. This yard was a perfect example of a considered-to-be-hunted-out area. I have been to areas like this one many times myself, generally to test new machines that make great claims, but the hunted out places have remained hunted out. Until now. The XP Deus is delivering the speed and performance that is needed to hunt tired old spots, for sure. Ground tracking on this machine works beautifully compared to the other top machines out there. And........... the XP Deus metal detector has non-motion pinpointing capabilities; it can track the ground in both pinpointing mode and detecting mode, which is a GIANT leap! It looks like the performance of the Deus is leaving the other big dogs in the dust, too, as far as recovery speed is concerned. The speed on the XP Deus is nothing short of phenomenal, which is something I do not say lightly. This super-fast recovery time is what makes such a difference when you are dealing with old and trashy areas. From the testing I have done to date, my review has to be very favourable. The performance has been very reliable and at no time over the last week or so have I run into any situation where one of the other top-end machines could have out-performed, or even kept up with this detector. Another little thing I'd like to mention is that the whole unit, including the supplied headphones and the coil, is wireless. Not only does that mean that there are no wires to get hung up anywhere, but it also makes the Deus incredibly light. And, if that is not enough, you can make it lighter still by just leaving the control box off and running the XP Deus from the controls on the headphones. Feather light! It is really nice for someone on the wrong side of 21... Fisher F75 Comments: the Fisher F75, like the F4 and F2, has outstanding features and performance. Operating at over 13 kHz, and with oodles of sensitivity, it can deliver on both high and low conductors (silver and gold). This detector is like a 327 Chevy engine with a hot cam and just street legal due to its high gain circuit. Its automatic back light system for night time hunting is the BEST I've experienced. Its depth is exceptional, but requires proper tuning to ensure stable hunting. Great light weight and well balanced feel in its category. See the Fisher F75 here Minelab Safari and Explorer series Comments: use FBS circuits or full band frequencies (28 ), Minelab's unique way to filter out negative ground and magnetic interference. The active frequency may be about 3kHz and the other harmonics act in concert to sample and neutralize ground noise and power lines. When the noise is neutralized, your ability to hear the deeper targets is enhanced. The 3 kHz will double the signal on deep silver vs other frequencies. The output is digital, and although the Explorer makes it easier to hear that deep silver without having to tweak, your lower conductors (gold, nickels and other jewellery) are usually ignored by most of the Explorer users. Foil, shards of aluminium and crown caps sound a little too good, where competitor's circuits chop those targets up. The Explorer has great gain and a smart find screen. The Explorer SE lacks an audio and visual pinpointing system; it uses a more conventional VCO pinpoint. All in all, these are nice, pretty deep metal detectors and are nice silver shooters. See the Minelab Safari here and see the Minelab Explorer SE here White's E Series DFX Comments: Although it is getting old now, when it comes to a do it all detector, the DFX 300 is still one of the top dogs. Not only is it a multi-frequency detector with 3 and 15 kHz, along with 18 other harmonic frequencies, but you can select to operate in 3 kHz for silver or 15 kHz for gold. Along with 55 basic and pro options you're in total control. The DFX, like the XLT, offers Sign graph technology but in addition to that you can adjust the sweep speeds, filters etc. The DFX 300 comes standard with the big 300mm coil, but my advice is to buy the optional 6x10" Eclipse wide scan, which significantly improves visual target ID in all ground conditions and gives improved target separation. White's XLT Comments: Discontinued. The XLT operates at White's traditional 6.59 kHz for very good response on silver conductive targets and good response on most gold jewellery but it is not up to the performance of the MXT on the lower conductors. The XLT shines in its Sign graph technology and smooth operation as it is a full filtered detector. On a dime at 8" the XLT can deliver a better target signal than the MXT or M6, but it requires a faster sweep speed to do so. The Sign graph technology will not only read out the target ID but it will deliver 1 bar up on round targets within 6" to surface. The XLT has been in the White's line-up for over 10 years and was preceded by the Eagle Spectrum and Eagle series (White's first digital detectors).No matter what you own, the XLT can complement your collection. Garrett GTI 2500 Comments: Bells and whistles, good depth but long in the tooth and on the heavy side. Garrett GTI 2500 offers a wide screen and although not as sophisticated as the other big dog competition, it does offer sizing technology A through E. Most coins and jewellery fall out in the B, with man hole covers in the E size along with some caches, I guess. This detector actually can be programmed to talk to you using a female voice. A poster on one of the forums, who is a single bachelor, actually put it on voice mode and slept with his GTI 2500... now that's love. Depth is above average for a single frequency detector at approximately 7 kHz and seems sensitive enough for gold rings. Ground tracks in the all metal mode. I suspect that the discrimination mode and ground balance point is automated in the chip and cannot be manually manipulated. see Garrett GTI 2500 here Minelab E-Trac Comments: this is the "minesweeper" for silver coins in parks. Newer technology allows you to hunt what you had to leave behind with the Explorer II. With a much faster response time, this is not your father's Explorer.... Minelab CTX3030 water proof Comments: the new CTX3030, with its color screen and too many features to mention, is clearly Minelab's new top-of-the-line coin/relic hunting machine. White's TDI SL Comments: nice. All that can be said about this newest incarnation of White's best pulse machine. metal detectors is WOW!!!! It is like the lightest version of the original TDI. Yes, lighter, smarter and faster. And it is cheaper that the original TDI, too! You are going to love it! This machine is a crossover, suitable for treasure hunting (coin, beach, relic) as well as gold prospecting. It is extremely deep and smooth enough to bring tears to your eyes! The original TDI was very popular with many serious detectorists, and this new incarnation is nice and a little lighter. White's V3i Comments: An eye popping colour display on a super LARGE screen and too many great features to mention make this machine 'the bomb'. Amazing audio, visuals, brute power and selectivity, advanced circuitry- and wireless headphone technology; over seven years of R&D brings you this manufacturer's most advanced flagship! White's VX3 White's LATEST Spectra VX3... straight forward, no-nonsense machine. Just received White's brand new VX3 this week. The name for the working project was EZV, which would have been a good name for the final product, too... White's engineers re-designed the user interface to be easier to access than that of the V3i. After checking it out myself, I found it very smooth and deep. Horsepower is the same as the Spectra V3i and uses the same Spectra Graph Screen. When you pinpoint the screen displays the strongest frequency with regards to the located target. The visual display of the Spectra Graph is by far the most informative in the industry and is very accurate where mineralization is involved. The live controls have been redone and the filter choice is reduced to 5 and 12. In testing, 12 seems by far the smoothest and is recommended for moderate to severe mineralization. First make sure you determine what you can and want to spend. However, there is a definite lower limit; below 300 Euro is little decent sale. The detectors must be priced lower unfortunately often seen as "toys". The performances do not correspond entirely with little or what the average amateur needs. A new comer to the hobby that starts at such little machine will be in this age of "overfishing" almost always dissatisfied with his results. Result: The hobby does not deliver the satisfaction that were expected, the detector will be located in the attic after unsuccessful sales efforts and the sad owner report to the local billiards club. The probability that the hobby or a success is much greater if you purchase a detector above 300 Euros. (If the owner ultimately report to the billiard club, then brings his detector at least still reasonable money!) We will be the "ideal detector" go and in more detail. Mind you, some for an ideal that is necessary for the other, of course, not to be! The data points are clearly below my personal vision as a detector amateur and especially as a technician. Everyone must weigh the various demands of his own needs to "ideal" to determine. His or her However, I think that the following points for a very large proportion of the readers of major importance, and I hope to show that I do not yet receive the attention they deserve. Many people the importance of several considerations ideal detector should have: 1 have a sufficiently large depth range. 2 Good discriminate and over a wide range adjustable. 3 Light and the focus should be high. 4 Sufficient to withstand bumps, dirt, and moisture. An easy 5-battery system, and prefer to work. On batteries 6 Decent priced and preferably from a known brand, so sell or trade-in is never a problem. These are some of the most important features, but personally I would like to add a few, who often receive too little attention: 7-The detector should be suitable for various types of dishes. 8-From a brand that gives good and long warranty, and should preferably accommodate for alterations or extensions. Preferably 9- are available at several places so that eg trade or service never comes to a dead track. Then there are some criteria which I consider correct are not necessarily needed. So a good average detector is not necessarily: 10-be Super Compact and folded to fit. In an attached briefcase 11-possess. A visual identification 12-to be present during the most violent rainstorms, tornadoes or tsunamis. Hassle employable I will do all these considerations motivating point for point, and everyone can judge whether he or she applies the same criteria themselves. 1 A good depth range I find essential. If the finds for grabs you can do with a lazy detector, but intense searched areas will only fit a detector is certainly a layout conjure. 2 Good discriminate; discrimination behaviour should be fairly "clean", so clearly reject and accept clear. Furthermore, the discrimination must also accept CCW iron. This I will explain later. 3 Light manageable; more important than the weight is the place where this weight is! A kilos under your arm is almost no problem. A search coil of a kilo is an absolute disaster! 4 Bumps, dirt and moisture. The dish should be a lot of cash. Here the toughest requirements apply. The electronics, however, can suffice with a sturdy table, provided they are not afraid of a few drops of rain. 5-Important! Every time the battery is changing around the corner. Usually resolved a bit ropey with 9V cubes. Detectors at the more affordable nutrition This is expensive, inconvenient, and this calls for break in the power supply wires. One of the two brands I NO longer want to fix necessarily took the cake: a whopping six 9V blocks were needed for this detector. The owner allowed me to build a special charger so he could work. With NIMH's future Price of only the NIMH's €155, -! The best works a cassette system as one of the major brands. All new models of this brand use the same "chocolate bar" that is filled with 8 penlight batteries or NIMH's. The penlight battery or NIMH has a very good price / energy and weight / power ratio. 6 A fair price is important., For most of us A good trade-or second-hand price is actually just as important. If you buy a well-known and popular detector later easily and conveniently sell or exchange will be. The above arguments speak for themselves. Which follow are still well worth considering: 7-Multiple types of dishes; for the advanced amateur round a must. Can you 80% of the land with your standard dish, the other 20% can significantly improve performance with a special dish. Example: many good universal detector chokes on dumping ground in the centre. A tiny saucer makes the noise knitting suddenly clear language. Even this we will quite elaborate once. 8-Lange and good service and warranty is a boon to the user. If the detector works flawlessly for years, its owner does so rarely. The Fix cables, broken battery doors, lost screws ...... It is therefore important that the problems quickly, cheaply and efficiently «nt to be resolved. This can invest enough in it. Unless the importer and its distribution 9-availability on multiple sites suggests a number of safe: The customer does not have to travel to purchase or service, far and if you dies dealer or flight to Timbuktu, there are plenty of dealers. Now the three points that are usually NOT so necessary. Although, of course it is always possible that an amateur for some reason DO hold on to advance one or more of the arguments below. 10-Super Compact sometimes comes in handy on vacation, you then take the detector in your hand luggage. The usual work? Oh, you actually would be a super compact shovel and super compact rubber boots should have, otherwise you shoot there is little along on! 11-Identification: Gorgeous, although not essential to enjoy fun in the hobby. Very useful if you have a lot looking at recreational beaches. 12-Stortbuibestendig or really waterproof? I'm not a compulsive seeker that I walk to dip. Among the harshest conditions in the mud A little rain can of course cause no harm to your detector, but the vast majority of detectors meet reasonable to rain resistance, which requires the average amateur. And then there I personally rather see my money is spent on looking perfect performance than on rubber gaskets and seals ... GERMAN GUN We will look at one of the most important aspects of contemporary detector further detail; discrimination. For starters, the discrimination must be put sufficiently low so that even iron is audible. "But I find no iron", I hear you say. Right. But let's look again at our "ruler". (Fig.1). disc ruler Right is the vondsten- and discrimination area. The vertical arrow represents the tipping point for which the DISC button is set. All items with a guide to the right of the crossover point will be heard, the rest will be discriminated against. An annoying trait of the discriminatiepricipe is that objects that are close to the tipping point are already quite lose their depth. The detection sensitivity of the accepted objects. disc sensitivity If your detector to minimum DISC all the iron clean wegdiscrimineert, so will not be a lot of sensitivity to smaller bronze and gold small objects. Remedy: further reduce the discrimination. Advantage: Hefty depth profit small bronze and gold. Disadvantage: You dig a sharp nail on a regular basis. The amateur should be able to control what he or she finds acceptable to junk finds. Locally self Search in All Metal is the other extreme; you dig you really mad at all the junk. No, better DISC is a scheme that is sufficiently low. Unfortunately, one of the bigger brands metal detectors such high minimum discrimination in various models. Too bad, but fortunately modifying properly. Another brand has a lot of annoying trait. Extra annoying because this is not just changing moment. To make this clear, I will tell you more about the internal structure of a detector. A detector has two internal measuring circuits, A and B. Circuit A is using the GEB knob set to the ground mineralization. Everything is on the ruler to the right of it, including all metals, will appear as a positive signal. Circuit B is using the DISC button is set to the type of discovery from which we want to accept it. Again, that everything is on the ruler to its right is considered positive signal will appear. In classical detector construction works like this: If both measuring circuits simultaneously give a positive signal, a beep will sound. Both circuits have to find the "approve" to get. Beep When, however, the different brand one works like this: When measuring circuit A is a metal, a beep. If circuit B finds that the metal of the type that should be discriminated against blocking the beep. A wants so beeping at each metal, and B throws on the brakes if it is junk. Now comes the punch line: Because A circuit using the GEBbeautiful bud is set on the ground, which is little affected by soil mineralization and thus will go nice and deep. Circuit B is contrast with the DISC-button set, and thus forced to NOT set to the ground. Circuit B is therefore less deep and is therefore unable to reject at the edge of its search depth is ... Practice junk: Detector is nice and deep, but deep junk sounds like a good metal. Just dig .. uh, oh no, yet junk! Users of such detectors will recognize the problem. For me it is a complete mystery why a manufacturer opts for such a system ... Rules to follow in the field As an amateur metal detector, you must observe the following rules: Be an ambassador of this great hobby !! Always ask permission of the landowner or manager of the land, or you may look on his / her land (take to be sure, especially in government land, legitimation along) Places where you should not go with a metal detector: protected cultural and historical sites such as. Castles, castles, ruins Archaeological Excavation sites (see eg www.kich.nl) sown fields pasture with cattle protect nature private property where you have not requested Let munitions lie. If there is danger, proceed as follows: stop immediately (excavation) work cover exposed portions of ammunition for sight with Earth mark the position and remember well how to find the place Notify the local police 'm definitely not weaponry dragging yourself! Never look at archaeological sites, unless you have obtained from the competent authorities (to help in an archaeological excavation). Permission See www.kich.nl Also protected cultural and historical sites such as. Palaces, castles, ruins and sown fields, pasture with cattle, protecting nature are places that should be left alone Make all the holes that you make neatly closed, treat nature with respect, make sure you plants, trees and turf is not damaged and let it all neatly behind. This also prevents further that people and animals can injure Take as far as possible all the metal what you think, even though it is not interesting, it. Consider the environment. Metals, especially copper and lead are bad for the environment. May even cause a further money at the hardware store these metals In the night without the permission of the landowner is prohibited. Someone that night looking for is suspected busy Finds, which one can reasonably assume or believe to be scientific cultural and historical value, must be reported to the mayor of the place to which the field belongs. The findings should also be notified to the relevant archaeological authorities. Buy some Books, SEARCH INTERNET, you tube over the hobby !!!!!!! More hobby’s on comeongetin.com ( See collecting coins ) Cleaning your finds testing first !! and at your own risk !! be careful !! Test and experiment that it is a delight before starting the real objects. In short, building a lot of experience in cleaning, everyone will finally enough clutter to your heart's content with it to experiment. Note the times and results of the experiments so that you know what you're doing. Distilled water: Is preferable to use distilled water and no piped water. In distilled no acids and minerals that corrode metals or discolour. Sit These are found to be in rain and tap water. Remember, boiled tap water is NOT distilled water. Of course, one can simply use water to test a cleaning method. (Clean) Shine: Do not use polishes, this often gives an unnatural shine. Use when brushing never hard brushes !, the only exception is iron. Instead, use a soft brush or cloth; For example, a trimmed toothbrush or nail brush. The short hairs are slightly stiffer. rinse: After each treatment, the items should be rinsed well, this is very important. When traces of acids, alkalis, etc. that remain by poor rinsing, come into contact with oxygen will find a greatly accelerated oxide formation takes place. Put the coins in a bath of distilled water. They may not overlap and should be regularly reversed. When this method is not followed, may cause discolouration on the coins. Occasionally water change is necessary because otherwise the water sours and chemicals «n continue to act. On coins After about thirty minutes, the treatment is completed. Rinsing is enough gold and silver objects. For other base metals copper coils alone is often not sufficient. The chemicals «n working at these metals deep into the coins through and cannot be removed. Using only coils The treated coins can be therefore better neutralized. Neutralization: Neutralizing and rinsing a method to convert. The significant effects of chemicals «n stop The advantage of neutralization is that it eliminates the direct effect of a particular substance. A used acid is neutralized by means of a liquor and a liquor by means of an acid. Dip the coin, and treated with an acid in a bath, for example sodium hydroxide. Hereinafter referred to as yet again rinse well, because the coin may be dependent on the strength of the caustic and the duration of the immersion have become basic. By means of flushing, the lye remainder removed. For the neutralization of acids include caustic soda and soda to household use. This is a considerably weaker liquor and can therefore be used only if the coins are cleaned with a weakly acidic solution. For the neutralization of alkali (such as, for example, sodium hydroxide) are, inter alia, citric acid and sodium bisulphate to be used. drying: Drying the coins must be thoroughly done, the combination of moisture with oxygen creates oxide formation. Drying is preferably done with a hair dryer. Breathable window drawings, e a strung with nylon mesh window drawing flies are also good to use. safety: Be careful when using chemicals. When making the solutions that the acids are done in the water and not the other (as you avoid splashes!). In terms of personal safety are indispensable: a good dust mask (face mask) gloves goggles or face shield clean tabard or clean old clothes ATTENTION !! Always perform the work in a well-ventilated area, various substances give off toxic fumes. Environmental requirements: When cleaning of coins and medals, one cannot do without acids and bases, but safe acids and bases do not exist! All finished fabrics - should be separately submitted to the (chemical of) municipal sanitation - an indication of the content. GOLD Is it gold ?, gold test: Let put together the following key water at the old-fashioned drug store; 30cc HNO3, oh, HCL 5cc and 70cc H2O. Rub the 'golden' object on a piece of black marble and bring the water to the stripes. If, after evaporation of the stripes are still present, it is gold. Gold objects and coins not oxidize, it means that require low maintenance. Should the coins are still clean, you can do so in the following ways: Light wash dirty coins with soapy water from non-corrosive soap. Polish with a mixture of salt and lemon juice. Soak in citric acid. SILVER Is it silver? the silver test; Mix 25g water, 5 grams of sulphuric acid and 2 grams dubbelchroomzue potash. Apply a droplet to a horizontal slice from the eye, if the red colour is silver. The redder the colour, the higher the silver content. Silver objects and coins discoloured by oxidation under the influence of pollution in the atmosphere, including sulphur. In Dutch provincial and Roman coins, it is not desirable to remove the oxidation (read patina) by the slight discoloration these coins just better appearance. Heavily soiled coins should be well cleaned. Different types of pollution require a different approach. Because it is difficult to say what is the best method MUST be first experimented with 'cheap' coins. Always remove the first vial resetting with a brush and water. Then one can apply one of the following methods. On the black spots a mixture of guest of salty and Chalk Powder apply immediately polish with a soft bristle brush. The objects rubbing with sigareas on a damp cloth. Rub with chamois. Shine powder of Soot. Rub with chamois. Chains etc. for about 15 minutes in boiling water with a lot of spirit salty. Polish with a woollen cloth with some chalk powder. Buff with (hot) salt. With ammonia; Let the coins for about thirty minutes in a solution of ammonia, then the coins brush, rinse well and dry. With ammonia; The pieces decoct in ammonia and let it cool The pieces rub fire with alcohol. Very good results you get, by rubbing with thinner. Away the pieces When a silver coin black is removed, or has black spots, is the best way to lay the pieces in a mixture of 50% citric acid and 50% water, they often move and turn the solution every three days update. For stubborn black spots, the treatment can last three weeks. The pieces in a solution of 50% soap solution, 25% ammonia and 25% fire alcohol present, this may take several days. Take a zinc plate of 15 cm to 15 cm, 2 large handfuls soda salt (sel de SOUDE) and water, let's quite boiling, throw the pieces in the solution. By a chemical reaction they cleanse without rubbing. With citric acid; Put the coins and few hours to a day, depending on the amount of dirt and the thickness of the oxide crusts, in a bath of citric acid, then brushing, rinse well and dry. By explaining what iron spikes on the bottom speeds up the process .. PLEASE NOTE that the nails do not touch the coins! With an acidic liquid; Silver coins, which are only slightly mottled, can be satisfactorily cleaned by rubbing a raw potato or by immersing in either sour milk or warm vinegar them under them; then rinse, drying and polish with a soft cloth. With Blackboard Chalk; For lightly soiled coins! Scrape or grate some chalk and make a fine paste of here. Rub with your fingers on the coin to remove black deposits wipe with a tissue. With silver dip; Furthermore, there are some resources under many different names (such as silver dip, quick silver, silver touchpad) in trade. These are usually good to use brown and black struck coins to clean quickly and effectively. The disadvantage of these agents, however, is that the stop is completely removed, and this is not always desirable. In Dutch provincial and Roman coins, it's better to get them to refresh with a cotton ball soaked in ammonia, after which they are rinsed and dried. COPPER, BRONZE, BRASS The metals copper, bronze and brass can be cleaned, the hardest one to aggressive treatment, the objects / coins cause irreparable damage. So go very carefully. Have a nice uniform patina intact. Begin always careful, you can always switch to other more aggressive methods if need be. With petroleum jelly; Not aggressive method! Copper objects and pieces of coins which are only lightly soiled, for example between the inscriptions, can be cleaned by rubbing. Using acid-free Vaseline The Vaseline can also be applied by placing the article. / Coin in heated petroleum jelly Allow to cool and withdraw, and then remove the Vaseline with a clean cotton ball, this leaves a thin layer of fat behind the copper or bronze virtually air sealing and prevents oxidation. Cleaned copper remains much more beautiful when it is rubbed. Immediately after neutralizing and drying with a cloth soaked in petroleum The objects / coins put in body oil. Depending on the degree of contamination, this can take several months. The objects / coins in household paraffin explain. This is something! stronger than olive oil, but also can be very lengthy, patience is a virtue after all. Make a very strong suds, decoct the pieces in it. Especially for gilded copper pieces brushing with slightly soapy water, which per liter of water 3 tablespoons ammonia and burn alcohol added. Do not use abrasive products, otherwise the gilding removed. With Real Soap; Lukewarm water and real soap, dry with chamois Soak it in kerosene and then brushing. Soak in a solution of 1.3 water, 3.1 vinegar, 1.3 ammonia, then brushing The pieces decoct in vinegar, which a large dose of salt has been added. As for silver use thinner. Brushing with Sour kohl, then polish with charcoal powder. Brushing with a mixture of soap, Brandy and Cretaceous. rub with spirit of salty and Green Soap (renew old copper) Rub with a cut lemon dipped in a paste of potato flour with vinegar. Wipe with powder sand, for example, gensse krachtige earth or charcoal powder. eraser; Slightly soiled items / coins rub with a piece SOFT eraser Bronze: rub with a rough cloth (terry) with chimney soot (coal?) Bronze: Put the coin in the Cola With only algae; Rub with animal fat, wipe with paper thin microscope the object Remove green slime by rubbing with ammonia, turpentine or kerosene Green slime prevent and remove; 3 parts of carbonic acid, ammonia, 1 part spirit of sal ammoniac and 24 parts water. Paraffin reining much copper species Common salt water, soak and polish with woollen cloth with chalk. With an acidic liquid; Less aggressive! Stains on copper coins can be by rubbing them with buttermilk mixed with salt also deleted; alternatives are lemon juice or sauerkraut and beer table. After rinse with hot water and polish with a soft cloth. With ammonium carbonate; Less aggressive! Stains on copper coins can be removed by soaking them in a solution of ammonium carbonate in water for several minutes. After good brushing, rinsing and drying. The coins can also optionally be rubbed with the solution. After rinsing, they should be equally buffed with a soft towel. Cooking in soda water; Less aggressive! Often one can easily achieve the goal of cleaning by boiling in distilled water, where some household soda is added to the coins. A bath of soda and glycerine; This is a less aggressive method! Put the coins in a bath of 10 parts of sodium hydroxide / household soda, 4 parts of glycerine and 100 parts of distilled water. As a result, the green slime of copper coins disappears and the oxide crusts largely solved. With a cleaning paste; Aggressive method! Make a paste of 8 parts of animal glue or gelatin, 150 parts of aluminium or zinc powder, 4 parts of glycerine and 10 parts hot distilled water. When this paste 24 hours on the metal has to interact, the coins are immersed in hot water. As a result, the paste will dissolve completely. Repetition of this treatment will result in complete removal of all corrosion layers. After neutralizing rinse well or better. With citric acid; Aggressive method! Let the coins 30 minutes to 1 hour, depending on the amount of dirt, soaking in a bath of citric acid. Hereinafter referred to as neutralization and drying. By vinegar or acetic acid; Something! less aggressive! Immerse the objects just below vinegar or acetic acid water, possibly some salt may be added. The duration of this treatment depends on the amount of dirt. After this treatment, the coins neutralization and drying. Make a solution of three parts water, 3 parts ammoniac, 3 parts vinegar, then rinse and dry as brushing, duration is about 20 minutes, slightly aggressive. ZINC Like iron coins oxidize also sink coins extremely fast. In contrast to the oxidation of the iron coins oxidation protection if the sink pieces of the object for further degradation. Zinc is non-magnetic. The white coating on the coins is not a disease, but only oxidation, there is no nml zinc plague. Wipe with a mixture of clay and chalk powder Make clear by brushing with a mixture of chalk and brandy. Complete the blank, by brushing with a solution of 1 part of sulphuric acid and 12 parts of water. With citric acid; Put the coins 10 Ã 20 minutes in the acid. The coins do have to be turned over several times during this time. After neutralizing again, brushing and drying. It is recommended to grease with Vaseline or other fatty substance, otherwise quickly discolouration coins after this treatment Only wash in soapy water very strong. Hard brushing with washing powder. TIN Tin is a metal fragile and there are some alternative methods Tin soldiers etc. freshen up with a solution of baking soda in water, rinse with lukewarm water with a little lemon juice. Not paints tin; The bluish color rendering by rubbing with cigar ash them. Not paints tin; The bluish color rendering by rubbing with turpentine in lukewarm water. clean with a paste of chalk and brandy. By brushing with soda water, vinegar or beer. clean Rub the pieces with a leek leaf (vegetable). Decoct in beer. Rubbing with poler watte IRON Iron as a coin metal is not propitious. Iron is therefore mainly used for the manufacture of emergency coins. With petroleum; Put the coins in an oil bath and rub them after a few hours with a cotton ball or cloth. However, this is not a pleasant method because of the smell of petroleum. With citric acid; Put the coins in a citric acid bath. After deposits and rust removed the coins neutralizing and drying. Rubbing with ashes of charcoal moistened with cooking oil Days soaking in petroleum. NICKEL, COPPER NICKEL Many modern coins are made of nickel or copper nickel. Nickel and iron coins can be distinguished from pieces of silver and aluminum, in that the former are magnetic. Nickel is a very hard metal. It has the durability that characterizes all precious metals. Nickel coins not oxidize and are not dark by sulfur compounds: they are thus rarely a stop provided. Clean with a cotton ball soaked in ammonia. Cleaning in thirty parts alcohol and 1 part sulfuric acid. Attack by acids cleaned by rubbing with staerineolie. Remove rust stains by rubbing with rind, then rub with a cloth with some amonia. Make nice shiny by rubbing with a flannel cloth with chalk and gin. ELECTROLYSE This is a method that can be aggressive. Applied to several materials depending on the conduction liquid used Use a glass jar, or any other material which do not transmit power. Use an adjustable 9 volt adapter. Make sure the adapetr ALWAYS been removed before you sit at the voorerp and make sure you have your hands are dry from the socket Cuts off the plug of the wiring so that you're talking about two separate wires. Find out what the plus and minus, sometimes the wires marked the thread with a thickening or a dash is the plus. Otherwise, use a multimeter. If you know what the + pole is, mark the wire strip the insulation off. Now you wrap the copper wire around a paper clip so this makes good contact at the top. Now wrap a piece of aluminum foil to the paper clip, squeeze it well, the whole should be about 6 inches long .. now attach an the - terminal of the adapter paperclip.Tussen the paper clip to the - pole terminal you object you cleaned. Obviously there are to come. Many alternatives on this idea Mix two tablespoons of salt with a dash of vinegar. Fill dissolved with water until all the grains of salt, and pour the solution into the pot. Put the + pole with aluminum foil on one side in the pot down, make sure the foil three inches, leave the top of the paperclip above the waves as much as possible and confirm with the clothespin at the top of the pot. Set the - terminal in the same way on the rim of the pot. Ensure that the object is completely submerged and that it does not touch the foil. The object you want to clean hole now bubbling / fizzing. If this is not done, the minus and plus pole must be exchanged. The water is dirty, the oxide falls off the object. Regulate the process by setting the voltage, always start with the lowest voltage! Get interim the object out of the water (from mains) and rinse and brush it clean. If necessary, repeat the procedure. CHEMICALS Used chemicals and their composition ammonia (NH 4 OH) solution: 1 part ammonia (and a concentration of 25%) in 2 parts of distilled water. ammonium carbonate ((NH4) 2CO3) solution: 1 part of ammonium carbonate in 4 parts of distilled water. acetic acid (CH 3 COOH) solution: 1 volume of acetic acid (at a concentration of 80%) in 15 parts of distilled water. citric acid (C6H8O7H20) solution: 1 part citric acid granules in 4 parts of distilled water does not use more than 150 g with the use of citric acid for the treatment of copper, iron or zinc coins in a liter of distilled water, that is to say 1 part citric acid granules in 7 parts of distilled water. phosphoric acid (H3PO4) solution: 1 part of phosphoric acid in 7 parts of distilled water; Add 7 grams of gelatin per liter of acid solution. household soda 1 sodium carbonate (Na2CO3) solution: 1 part household soda to 4 parts distilled water 7 caustic soda solution: 1 part sodium hydroxide (NaOH) / household soda (Na2C03) to 10 parts distilled Often you 'll already have a coin counter that does not look .

It is not the purpose of cleaning the original color and luster comes back , but to make a mint beautiful and so attractive when the coin is really dirty. So just never clean a coin . A coin does not . Cleanse your best However, at extremely high oxidation . Do you want them anyway cleaning methods than are recommended . Copper coins . A copper coin can be used as best cleaning by taking vinegar and there to add . Much salt The salt will not dissolve immediately , but after a while it is resolved. Possibly let you decoct the coin in vinegar . Caution : Do not take acid ! Vinegar is only 6 % - 8 % acetic acid , and the rest is water, while acetic acid 100 % concentrated and burning for your body . A copper coin should never be too long in the vinegar . Sometimes it is a matter of seconds . The brown color is gone and the original color of the coin is more or less back .

It is possible that you will deflect brown coin . Again after a few hours or days Probably you have the coin or not properly rinsed off with water or not be long enough to dry before you return is inserted. Coin in a coin holder sinking coins When cleaning sinking coins go like work. Copper coins Only this purpose , use of citric acid in place of acetic acid with salt. After cleaning, rinse the coin you obviously thoroughly with water. silver coins After some time, silver coins begin to turn black. This treatment is best in a bath of dilute ammonia . Euro coins To clean coins you could use vinegar. When a currency not in circulation has been so long, but already has some oxidation spots , you can clean it with acetic acid . The coins of 1 and 2 euro , 10 cents , 20 cents and 50 cents can then beautiful shine just like new . Only the 1 , 2 and 5 cents , the result is less good . Beware ! These coins can oxidize back quite quickly . You use the same method as explained in the copper coins . Other cleaning methods The easiest method to clean a coin with soap.

Nevertheless, there are collectors who do this. soft top Wash your hands with soap. Washing up will remove the oils and tiny grit from your fingers. Lay down a soft towel. Place a soft towel, folded over a couple of times, on your working surface to catch coins you might drop, and to provide a space for them to dry. Set up your soapy bath. Fill a small plastic container with warm tap water. Do not use glass, china, or metal, as these hard surfaces can scratch your coins! Disposable food storage containers are perfect for. Add a litlle amount of dish-washing detergent to the container filled with warm water. Don't overdo it - all you need is a really little bit. Prepare your final rinse bath. Fill a second plastic container with distilled water, for final rinse. Although distilled water is by far the best, you can also use hot running tap water. Clean the coin. Pick up the first coin, and immerse it in the soapy water. Gently rub both sides of the coin between your fingers, paying attention to any stickiness or gunk. Rub gunk near the edges away from the center of the coin, not into it. Always work in an outward pattern. Dirt and gunk near the edges should simply be made to go over the side with your thumb, not all the way across the coin. Don't put all of your coins in the water at once! Do them one at a time, to avoid their coming in contact with each other and causing scratch marks on the surfaces. Rinse the coin. Rinse the coin under running water, gently rubbing until all soap residue is gone. Always remember, gentleness is the key! Don't rub hard, and if you feel any grit, even light grit, don't rub it into the coin because it will scratch the coin very easily. Instead, sort of agitate the coin by moving it quickly in the water to dislodge the grit, touch it gently only if needed to free it up. Every motion you make with your fingers should be focused on not causing scratches to the coin's surface. Do the finishing rinse. turn the coin around in the distilled water, to remove the chlorine residue and other contaminants that are found in tap water. Hold it by the edges and agitate gently. At this point, you should no longer touch the coin on its faces. Touch it only by the edges when using your bare fingers. If you must use tap water for the final rinse, then run the coin under fairly hot water. Allow the coin to dry. If you use a distilled water rinse, you can set the coin on the towel to air dry. The coin should dry spot-free, because distilled water is free of dissolved minerals and other impurities. If you had to do the final rinse in hot tap water, then gently pat the coin dry to help prevent spotting. Never rub a coin dry! pat it dry gently with a soft cloth or tissue. Repeat until finished. Now wash the rest of your coins, one at a time, following Steps 5 through 8 carefully. If you run across a coin that needs to soak for a while to get clean, put it in the tub of water off to the side, so you don't accidentally ding it with another coin you are working on. Store your coins. Make sure your coins are absolutely dry before putting them away. Damp coins can suffer damage over time. Remember to always handle coins only by the edges. also 3 components for cleaning coins Silver coins : Get a small pinch of baking soda between your fingers and just start rubbing the coin over and over. Again, if it’s a non-silver coin it will help a little, but on a silver coin it will make it look 80% better. Necessary tools to clean : 1. Brushes: an electric toothbrush, a plastic or fibre glass brush. A brass brush works the best. 2. Detail tools. Either a toothpick or a soft metal pick for cleaning between letters etc. 3. Cotton swabs for cleaning slightly dirty coins 4. containers for your solvents etc. The best way to clean coins is using olive oil. Simply soak the coins in the oil for about 4 days (in some instances coins must soak for much longer periods). After removing the coins from the olive oil you put them in a cup with one tablespoon of warm water and TSP (tri-sodium phosphate)about 1/4 TSP 3/4 water}.TSP is available at any place that sells house paints. Shake the cup and the let it settle for about 5-10 minutes. Rinse the coins in water to remove the TSP( always use distilled water, tap water will leave mineral deposits, which cause black dots on coins). Use an old toothbrush or other type as mentioned above and gently brush away the dirt. Some coins will clean up very nicely. The ones that still have dirt caked on, should be placed back in the olive oil. Repeat the process until you are satisfied with the results. Don't rush the cleaning process. You'll be amazed at some of the results using this method. Chemicals used and their composition. ( all the cleaning is at your own risk ! ) 1. ammonia ( NH 4 OH )solution: 1 part ammonia ( and a concentration of 25%) in 2 parts of distilled water . 2. ammonium carbonate ( (NH4) 2CO3 ) solution : 1 part ammonium carbonate to 4 parts distilled water . 3. acetic acid ( CH3COOH )solution: 1 volume of acetic acid ( in a concentration of 80%) in 15 parts of distilled water . 4. citric acid ( C6H8O7H20 )solution : 1 part citric acid granules 4 parts of distilled water does not use more than 150 grams with the use of citric acid in the treatment of copper , iron or zinc coins in a litre of distilled water , that is to say 1 part citric acid granules in 7 parts of distilled water . 5 . phosphoric acid ( H3PO4 ) solution: 1 part phosphoric acid to 7 parts of distilled water, add 7 g of gelatine per litre of acid solution . 6. household soda 1 sodium carbonate ( Na2CO3 )solution : 1 part household soda to 4 parts distilled water 7. caustic soda solution : 1 part sodium hydroxide ( NaOH ) / household soda ( Na2C03 ) to 10 parts distilled water . Ultrasonic cleaning : Well I can say with confidence that Ultra Sonics are the way to go, you only have to be on top of the situation watching out how long you leave it in there, For silver coins It's the cat’s meow, For bronze coins It's also great, but you have to watch out, it will take off pagination. NOW the type I purchased K&E LEROY ULTRASONIC It's a LAB GRADE ultrasonic cleaner, has variable Automatic Frequency adjustments(It's a degassing stage, then 1st clean cycle then 2 clean cycle and so on, the water actually gets hot from the frequencies employed. It's right at the moment cleaning one of my silver coins with heavy hard encrustations, after 20 min. there is discoloration of the distilled water and the crust is pitting and falling off. Use only distilled water for cleaning solution as ultrasonic vibrations produce heat and, therefore, the solution being used will evaporate. If there are salts and other chemical compounds in the water, they will not only affect the coin being cleaned but also may cause health hazards if their vapours are inhaled. The cleaning solution should be made up of distilled water, a dab of dish soap (use a toothpick to add a dab into the solution to provide a better action of ultrasound) and a dab of de-foamer. Using a mild detergent solution, ultrasonic cleaners work very well on silver coins. Copper and nickel coins may require stronger detergents or oxide removers to dislodge grime and corrosion. You may add commercial cleaners designed for specific metals. Prior to the ultrasonic cleaning, soak your coins in distilled water until some encrustation and/or dirt deposits are about to come off, use a hard nylon brush to scrub away most of them. Suspend a plastic cup or a small container or a basket (the smaller ultrasonic machines come with plastic baskets) into the cleaner's pan. Rig the cup with a common wire hanger in such a way that the cup is in the water but not touching the stainless steel pan which is filled with just distilled water. Pour the solution into the cup and up to the level of water in the cleaner's pan. The cup does not reduce the cleaning effect at all. During the process, the cup will catch the dirt falling off the coin and stop it from falling to the bottom of the pan and affecting oscillation. Any dirt or crud being present in the main pan will affect the cleaner's performance and can greatly shorten the machine's lifetime. The cleaning solution in the cup can be changed without dirtying the water in the main pan. DON NOT put the coin on the bottom of the cleaner's pan at all! The vibrating bottom of the ultrasonic cleaner and the dirt coming off the coin will cause numerous micro scratches and polishing marks on the coin's surface; thus, devaluing the coin. And the banging of coins against the steel bottom will cause flat spots on the coins. Before After Ultrasonic cleaning COIN Suspend the coin attached to a paperclip on a string off a stand (made of an old coat hanger wire) into the cup and within an inch of the solution level. The coin should be hung in a perpendicular position to the bottom. Such coin placement will provide maximum "cavitation" - sudden formation and collapse of low-pressure bubbles in liquids by means of mechanical force such as ultrasound waves. The more cavitation you can create, the faster the ultrasonic cleaning process. Addition of the little dab of dish soap helps in increasing the cavitation. If you do not have the old wire hanger at hand, you can use a nylon pyramid tea bags (without tea of course) with the string for placing the coin into it and suspending it into the cup. The only drawback of using a tea bag is that it is difficult to position the coin properly. Other means can be a piece of a plastic window screen from which you can make a "coin bag" for the coin to remain in a perpendicular position to the bottom. Turn the cleaner on, and allow it to run for a few minutes. Switch it off, take out the coin, and inspect it to see how much dirt has been removed. As you see results after the first run, you will be able to estimate the extension of cleaning required. If the coin only had a light coating of dirt or gunk on it originally, it should have been cleaned by now. During next run, do NOT let your machine run for more than 50% of its duty cycle. Stop it on time and allow the cleaner to cool off. Change the solution or just add distilled water to the cup. Brush all the loosened dirt off the coin. To get the crusty spots, run a few cycles of cleaning followed by brushing after each run. Keep checking frequently as to the progress and stop when you’re feeling happy about the job. Do NOT ultrasound the coin for any longer than necessary as the coin's patina would also be attacked and may be destroyed. The patina of a coin is the layer of surface metal that has changed as a result of interaction with environmental agents or contaminants. On modern coins, a patina is generally considered to be undesirable damage to the coin's surface, and is often synonymous with tarnish or toning. On ancient bronze coins, however, which have usually been buried in the ground for 1,500 to 2,500 years, the patina is not only desirable, but practically essential. The colour of the patina on ancient bronze coins is usually green, and can range from very light green to a deep, lustrous, dark verdigrises’ green. Sometimes patinas are seen in other colours, as well, such as blacks, reds, browns, and yellows. happy DETECTING AND DIGGING COME ON GET IN AND OUTSIDE WITH THIS AWESOME HOBBY !!!!!!!!!!!!!!!!!!!!!!!
