The PETREL 3 FISCHER 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.
