Petrel 3 Monitor (4-Pin) – Integrated CCR Dive Computer with Direct PPO? Monitoring

The Shearwater Petrel 3 Monitor (4-Pin) is a compact, rugged technical dive computer engineered for rebreather divers who depend on direct wired PPO? monitoring through a 4-pin interface. Built for reliability in demanding conditions, it connects directly to compatible CCR systems, delivering real-time PPO? readings, decompression status, and system feedback on a bright, full-colour AMOLED display.

With a strengthened aluminosilicate glass screen, a corrosion-resistant titanium bezel, and Shearwater’s trusted Bühlmann decompression algorithm, the Petrel 3 Monitor (4-Pin) is designed for caves, wrecks, technical depths, and harsh expedition environments. The two-button interface offers predictable, glove-friendly navigation, while vibration alerts and Bluetooth connectivity enhance usability above and below the surface.
