Used Shearwater Petrel 2 Computer

Product Description

The Petrel 2 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. Also new with the Petrel 2 is a richly featured ‘gauge mode’ configuration. The included CCR mode for rebreathers provides the ability to perform constant PO2 set point calculations for deco. An optional PIN upgrade to the Varying Permeability Model (VPM-B and VPM-B/GFS) decompression algorithm is now available. 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.
