The Suunto Cobra 3 Black dive computer includes a quick release and USB cable for downloading and sharing dives. The Cobra 3 Black is a sleek, new design but still incorporates all the original features of the Cobra 3 from Suunto. Suunto have added an electronic 3D compass which is not only easy to read and operate but also offers divers the unique ability to tilt the compass up to 45 degrees in any direction without impairing the ability to read figures accurately.

The Cobra 3 Black continues to have two-gas switching Nitrox, Air, and Gauge modes and is an air-integrated computer so will monitor and display pressure, track your rate of air consumption and will continuously calculate your remaining air time. The Suunto Cobra3 also provides visual and audible alarms for depth and pressure and warns you when you’re running low on air so that you are free to focus on the dive.

The Suunto Cobra 3 black dive computer uses the Suunto Deep Stop RGBM algorithm, that features continuous decompression for optimal ascent time. For deeper dives, the Deep Stop option adds further protection with a series of “deep stops” between your maximum depth and ceiling.
