Edy II
By Cressi
Description
The Edy II combines complete programmes for three different types of dives in one
single instrument: 1- scuba diving (air or Nitrox) 2- technical diving (depth gauge
and timer to a depth of 200 metres) 3- free diving.
Edy II is also an attractive,
compact digital wristwatch. It has dual time zones, an alarm function and the
display is back lit so that figures can be read even in poor lighting conditions. 1 – The SCUBA DIVING COMPUTER mode allows you to choose between the use of
air or a Nitrox mix with up to 50% oxygen, with partial pressure of this gas of
between 1.0 and 1.6 bar that can be chosen by the user. Three different safety
levels can be set (Safety Factor), a maximum depth alarm that can be inserted if
and when required, graphic display of nitrogen saturation and CNS oxygen toxicity,
graphic indicator of ascent speed, thermometer and a wide range of audio and
visual alarms.
A particularly high performance logbook memorises a large amount of data from
the last 30 hours of dives or of the last 60 dives, which can be scrolled through,
one by one, at intervals of 30 seconds, thanks to the integrated Profile function
which does not require any accessory interface. A handy History function
memorises maximum depth, hours spent in the water and total number of dives
performed. 2 – In GAUGE mode Edy II is a valuable instrument for those who wish to
programme the dive using decompression software and perform dives in
accordance with tables, as required in technical dives. The functions indicated
provide the instant and maximum depth, the dive time (including seconds!),
indication of ascent speed, a thermometer, a traditional watch and a handy
chronometer (hours, minutes and seconds) to accurately calculate ascent and
decompression stops. A depth alarm can also be enabled if and when required. The
GAUGE mode also has its own logbook which even calculates the average depth of
the dive and records the temperature at the maximum depth reached, it also has a
Profile function to review the dive at intervals of 30 seconds and an independent
History function to record only those dives performed in GAUGE mode. 3- In FREE DIVE (FREE) mode all the needs of the free diver have been taken into
consideration. Therefore indications of current and maximum depth are provided
as well as dive time (minutes and seconds), ascent speed and a depth and/or time
alarm can be enabled. On the surface the interval between one dive and the next is
indicated (minutes and seconds) and there is also a thermometer. This mode also
has its own independent Logbook that is able to memorise up to 60 dives, filled
with data, each of which can be reviewed with the integrated Profile function at
intervals of just one second. The History section memorises the total number of
dives on the day, indicating the deepest dive and its duration. This daily memory
can be reset at any time.
The battery of the Edy II can be quickly replaced by any
watchmaker. An accessory interface is available to download all the data
recorded and transfer them to a PC, thus allowing the user to access many more
functions.

Archimede II
By Cressi
Description
The second version of the Archimede computer, with its renewed look, has new
sophisticated software that is able to manage two different Nitrox mixes during a
dive, thus allowing you to choose at any time during the same dive. The features
of Archimede, which were already outstanding, have been considerably improved
for scuba divers and free divers as well as technical divers, who will find the new
GAUGE function an indispensable instrument for precise monitoring of all their
dives.
Archimede 2 is, first of all, an intuitive computer that is easy to use, both for the
beginner and the professional. Although it has many functions you are not obliged
to use them. Once the computer has been set for the use of air it does not require
any further adjustment for subsequent dives as the computer activates
automatically upon contact with the water and is perfectly able to calculate any
dive, with or without decompression, in total automatism. However, even the
most demanding divers have been taken into consideration, those who use Nitrox
mixes and want to de-saturate in greater safety, by using Nitrox mixes whilst
ascending, or who want to use the instrument during free diving or technical
dives. The new software analyzes the data of 12 sample tissues (previously 9)
for even more accurate monitoring of tissue saturation and de-saturation
mechanisms. The possibility of being able to use a second Nitrox mix during the same dive has
now been introduced to faithfully monitor and assist those divers that prefer desaturation with Nitrox mixes, a practice that offers greater safety to the dive and
that is used by an increasingly large number of enthusiasts. The first mix can
contain a percentage of oxygen ranging from 21% (air) to 50%, the second
between 21% and 99% (pure oxygen). The fraction of oxygen of both mixes is set
on the surface, whilst the use of the two different mixes can be chosen at any time
during the dive. Naturally, the partial pressure of both of the mixes can also be
selected in a wide range of between 1.0 and 1.6 bar.
Other new functions include
the maximum depth indicator, which is now visible during decompression; the
choice of three different Safety Factor levels; the ascent speed indicator
(expanded); the temperature sensor (faster) and the display back-lighting
(clearer). Lastly, the all new GAUGE function, used both for free diving and
technical dives, which selects just some of the instrument’s functions, such as
instant and maximum depth, duration of the dive (in minutes and seconds), time
and ascent speed. The operating range of the GAUGE function reaches depths of
up to 200 metres.

Mini Console II
By Cressi
Description
Mini 2 Gauge Console (Metric/Imperial)
Mini-console 2 is a small compact console
that houses the Cressi mini pressure gauge and a new, small, analog depth gauge.
Both gauges are high quality instruments with a chrome plated brass case and the
depth gauge has a diaphragm membrane function. Both gauges have a large
circular easy to read scale.
On the luminescent face of the 70m/230ft depth gauge the first 12m/40ft depth
readings are in 3m/10ft increments, (which correspond to the area of
decompression stops), and are widely spaced for ease of reading. The face is
divided into three different colored zones: green up to 20m/66ft, light blue from
20m/66ft to 40m/130ft, red from 40m/130ft to the end of the scale. The
instrument has a maximum depth indicator that stops on the maximum depth
reached during the dive.
The Mini-Manometer pressure gauge luminescent dial reads from 0-to 350
bar/5000 psi. The instruments face like the depth gauge is divided into three
different colored zones: the area from 35 bar/600 psi and below is highlighted in
red with a solid bar and red stripes. If gauge is used on deeper dives, the red scale
extends and fades to 70 bar/1,300 psi. This provides for added reserve air
indication required at greater depths. From 35 bar/600 to approximately 200
bar/3,000 psi is green and from 200 bar/3,000 psi to end of scale is blue.
The front glass lens is made to act as a pressure relief valve. In the event of a
sudden increase in pressure inside the instrument, the glass rises slightly, allowing
the excess pressure to escape. The instrument is housed in a small, modern shaped
console boot, made from polycarbonate and desmopan, (a thermoplastic
polyurethane) two materials that guarantee protection from shocks, scratches and
which, at the same time, is very light.
The pressure and depth gauges are positioned in such a way that both instruments
can be read quickly and easily in any conditions. At the end of the console, slightly
to the sides, there are two loops for fastening the instrument to the BCD or
harness so that it does not hang down with the risk of catching and damaging the
environment.

SPG
By Cressi
Description
The Cressi mini pressure gauge is a small, light-weight gauge that has been
specifically designed to avoid excessive strain on the HP hose that connects to the
first stage of the regulator. The instrument has a metal case in chromium plated
brass and is therefore extremely strong.
The front glass is made so that it also acts as a pressure relief valve. In the event of
a sudden increase in pressure inside the instrument, the glass rises slightly,
allowing the excess pressure to escape.
The luminescent dial is calibrated up to
350 bar in the metric version and 5000 psi in the imperial one.
The area below 50 bar is highlighted in red, the one between 50 and 200 is green
and that from 200 to the end of the scale is light blue. The instrument is housed
in a small, modern shaped console, made from polycarbonate and desmopan, two
materials that guarantee protection from shocks and scratches and which, at the
same time, are very light.
In the upper part of the protective shell there is a loop
for fastening the instrument to the jacket so that it does not hang down with the
risk of catching and damaging the environment.
