  • USED IST Data + Dive Computer

        The 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.

        1. Algorithm based on Swiss model
        2. 2 programmable NITROX mixtures (mix.1 – 21~50%, mix.2 – 21~99%)
