The Shearwater Petrel 2 is a full decompression dive computer incorporating the Bühlmann ZHL-16C algorithm, with user configurable Gradient Factors (GF) which allow the diver to control their dive computer decompression calculations. Onboard you have open-circuit and closed-circuit Air, Nitrox and Trimix mixed gas functionality. An optional PIN upgrade to the Varying Permeability Model (VPM-B and VPM-B/GFS) decompression algorithm is also available (sold separately).

Available for local pickup, or for delivery within the Philippines


The Petrel 2 includes a richly featured gauge mode configuration, along with a three-axis tilt-compensated digital compass. The included CCR mode for rebreathers provides the ability to perform constant PO2 set point calculations for deco. During a decompression dive, the Petrel 2 provides complete information displays of all required stop times.

The Petrel 2 can provide time-to-surface based on look ahead at planned gas switches. Multiple gas definition presets are supported with any combination of oxygen, nitrogen and helium. The Petrel 2 will  not lockout after a missed stop or ascent rate violation. The Petrel 2 offers a screen display utilizing a low-power consumption, 320×240 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.

The Petrel 2 has been designed to accept any type of AA size battery including alkaline, lithium and rechargeables. Included with every Petrel 2 are two elastic straps with buckles, gold contact battery holder and battery already installed, USB Bluetooth adapter, mini-CD with Petrel Manual (PDF) and printed Quick Start Guide with instructions for downloading software from the Shearwater Research website. The Petrel 2 also includes a titanium bezel and a screen protector already installed to help prevent scratches of the display face. The software includes a complete dive log manager, compatible with both MS Windows and MAC OS X. The dive log manager supports log downloads and firmware updates via the Bluetooth wireless interface of the Petrel.
