  • The upgraded Shearwater Petrel 2 Ext Dive Computer with new titanium bezel has all the features of the standard Petrel 2 but includes a Fischer 103 I/O port used for external PO2 monitoring of up to three oxygen sensors in a rebreather loop.

    The Petrel 2 is a full decompression dive computer that uses the Buhlmann ZHL-16C algorithm with customisable Gradient Factors but can be upgraded with the Varying Permeability Model (VPM-B and VPM-B/GFS) algorithm at a later date.

    The Petrel 2 is a highly customisable dive computer that supports recreational, technical open circuit and closed circuit straight out of the box., along with a three-axis tilt-compensated digital compass. The Petrel 2 is fitted with a high resolution QVGA, full colour LED backlit LCD display which offers low energy consumption for longer battery life. 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 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.

    Once the Petrel 2- 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 å±20%, it passes voting. The system average PPO2 is the average of all sensors that have passed voting.

    For simplicity and availability the Petrel 2 runs using an AA battery. Lithium versions are recommended for improved battery life but alkaline are also accepted. A USB Bluetooth adaptor is also included for connectivity to desktop and smart devices for data transfer and firmware upgrades.
