 On
the market today, monitoring armbands
cost anywhere from $100 - $200.
 Other
armbands do not monitor body
temperature.
 Other
products have confusing computer
application.
 Some
products have chest straps.
Mio 0034US – BLK, Energy Pro Plus
Chest strap with heart rate zone
indicators.
$99.95
[2]
Polar RCS5 Red Watch
Chest strap with calorie counter and
is water resistant.
$179
[3]
 Develop
the product to cost less than
$100.
 Monitor
body temperature.
 Design
computer application to be easy
to operate for any age user.
 Monitor
heart rate with finger strap.
