Overview
The PETREL 3 gives divers our most connected experience. A stunning, easy-to-read, 2.6” AMOLED display is protected by a toughened glass lens, titanium bezel, and piezo touch buttons.
Air integration is standard with up to four Shearwater transmitters to customize a solution from open circuit to rebreather and bailout gas pressure monitoring.
Safety is increased with a strong vibration alert system, and a user-changeable AA battery offers long dive times and ease of replacement.
PETREL 3 is available in standalone or rebreather monitoring models, including DiveCAN, 4-pin AK, and Fischer port connections.
