The PETREL 3 has 4 different dive modes:

OPEN CIRCUIT RECREATIONAL: in this mode the PETREL 3 works like a full-featured nitrox computer and is able to handle 3 different gases. The perfect mode for the serious recreational diving enthusiast. Includes adaptive safety stop and NDL bar graph.

OPEN CIRCUIT TECHNICAL: in this mode the PETREL 2 can handle 5 gases and is Trimix enabled by default.

A 2.4" big display let's you customise which information you want to see where. Find your way with the integrated 3 axis, tilt compensated digital compass. The PETREL 2 can be set to different languages including French, Spanish and many more. Download dive details and log using Bluetooth technology.

Our personal note: a really great computer companion from your first underwater kicks to your more advanced diving adventures.
