The Petrel2-EXT includes a Fischer 103 I/O port used for external PO2 monitoring of up to three oxygen sensors in a rebreather loop. Once the Petrel2- EXT is plugged in to the sensor cable via the Fischer 103A connector and calibrated it uses the PPO2 input from the sensors to determine the system average PPO2 used for decompression calculations and CNS tracking. A voting algorithm is used to decide which of the three sensors are likely to be correct. If a sensor matches either of the other two sensors within ±20%, it passes voting. The system average PPO2 is the average of all sensors that have passed voting.

The Petrel 2 from Shearwater Research of Canada is a full decompression dive computer incorporating the Bühlmann ZHL-16C algorithm, with user configurable Gradient Factors (GF). Gradient Factors allow the diver unique and individual control of their dive computer decompression calculations. An optional PIN upgrade to the Varying Permeability Model (VPM-B and VPM-B/GFS) decompression algorithm is also available. 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. Out of the box, all models include 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.

The Petrel 2 has been designed to accept any type of AA size battery including alkaline, lithium and rechargeables. Included with every Petrel 2 from Dive Gear Express are two elastic straps with buckles, gold contact battery holder and battery already installed (ready to dive out of the box!), 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 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.
