The Suunto Vyper Air includes optional wireless air integration and a technologically advanced electronic 3D compass. With wireless air integration, the Suunto Vyper Air allows divers to monitor tank pressure and air consumption from the computer on your wrist. The Vyper Air?s new electronic 3D compass has user adjustable time out and offers divers the unique ability to tilt the compass up to 45 degrees in any direction without impairing the ability to read figures clearly and accurately. - The Vyper Air includes Air, Nitrox and Gauge modes and gas switching. For divers using enriched air, the Suunto Vyper Air can be programmed in one percent increments for nitrox mixtures between 21 and 100 percent oxygen. Divers can also adjust oxygen partial pressure between 0.5 and 1.6 in 0.1 unit increments. The Suunto Vyper Air uses the Suunto Deep Stop RGBM algorithm that features continuous decompression and optimal ascent time. For deeper dives, the Deep Stop option adds further protection with a series of ?deep stops? between a diver?s maximum depth and ceiling.
