Description

The Shearwater Petrel 3 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.

It has a high resolution 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 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 and 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.
