Description The PERDIX 2 is Shearwater’s toughest and most reliable full-size computer yet. The armoured casing with precision titanium surround bezel and dependable titanium piezo touch buttons protect performance-enhanced electronics. An aluminosilicate glass lens guards a fantastic 2.2″ bright screen and offers improved clarity, impact, and damage resistance. A strong vibration customizable alert system draws attention at critical moments of the dive. Air integration with up to four Shearwater transmitters allows room to grow from a first computer to a powerful, proven advanced technical diving solution. This is delivered using the trusted and easy-to-find user-changeable single AA battery and familiar ergonomic compact form factor. PERDIX 2 is available in Ti, Ti Black, and Journey’s edition colour finishes.

The simplified settings allow for three breathing gas mixtures (Air or Nitrox) and places a greater emphasis on the maximum operating depth (MOD) and no decompression time limit (NDL). The display prominently warns the diver if their depth is near, at or exceeds the MOD of the selected breathing gas. The diver also simply selects one of three levels of NDL conservatism and during the dive a bar graph turns from green to red as the diver approaches the NDL. An optional 3 minute countdown safety stop starts when the diver reaches shallower than { 20 feet | 6 meters } on the ascent. If the diver exceeds the NDL and requires stops, the display turns red and warns “DECO STOP” with the mandatory depth and stop times.
