DATA + is a smart, lightweight wrist-top computer that provides all the essential information a diver will need. Upon self-activation underwater, this sophisticated unit begins collecting data such as depth, temperature and dive time at a regular interval and by taking air / Nitrox level input by the diver into calculation, the advanced software automatically gives precise nitrogen saturation level in the body. Along with other diving and safety specific data (ascent rate, partial oxygen level, safety stop timer), all are displayed on a large, easy to read screen.
 
Despite the complex design, IST’s new GP-3000 dive computer is incredibly user friendly: its simple, 3-button interface lets the diver easily input information and change between 7 different functions, even with thick gloves; common CR2032 button battery is used and is user replaceable; dive log stored in the computer (up to 60 dives) can be simply retrieved into a personal computer through a specially made PC interface and a software (available separately).
