Shearwater - Petrel 2

Shearwater - Petrel 2

The Petrel2 Dive Computer from Shearwater Research of Canada incorporates a powerful feature set, easy to understand menus, easy to read full color display, Bluetooth wireless upload/download and a robust compact case. The Petrel 2 has been designed to accept any type of AA size battery including alkaline, lithium and rechargeables. Out of the box, the Petrel 2 includes open-circuit and closed-circuit Air, Nitrox and Trimix mixed gas functionality. The Petrel 2 offers a screen display utilizing a low-power consumption, high resolution QVGA, full color LCD display. The display will automatically adjust intensity based on available light to make the display easily readable whether on the surface in sunlight, in open water or in a cave.

Recreational Nitrox Configuration of Shearwater Petrel 2

The Petrel 2 has a technical open-circuit mode and a rebreather mode; both modes support diving with trimix plus options for planned decompression. Recreational sport divers, who dive only air or nitrox within no-stop required time limits, often find the extensive technical diving displays and option menus unnecessary. When set in the recreational open-circuit mode (aka recreational nitrox mode), the sport diver sees only the features and options meaningful to their style of diving. Also, Shearwater has a simplified Petrel 2 Recreational Nitrox User Manual written exclusively for the sport diver audience.

For Petrel 2 owners who perform more than one style of diving, such as instructors, the computer can be easily switched between any of the three modes (recreational open-circuit, technical open-circuit, and rebreather) with no penalty as all decompression calculation data is retained (except when switching to gauge mode).
