Designed and built in Vancouver, BC, the Petrel 3 features an enormous 2.6” AMOLED display shielded by a heavy-duty titanium bezel and a toughened aluminosilicate glass lens. Built to withstand punishing environments, it integrates wireless air tracking for up to 4 transmitters, a 3D tilt-compensated digital compass, strong haptic vibration alerts, and runs on a single user-replaceable AA battery. Whether you choose the Standalone or Fischer connector model, the Petrel 3 delivers unmatched reliability and clarity when you need it most.
Official Shearwater Petrel 3 Key Features
- Massive 2.6” AMOLED Screen: Ultra-bright, high-resolution AMOLED display with deep blacks and vivid colors ensures maximum legibility in pitch-black caves and low-visibility wrecks.
- Titanium Bezel & Toughened Glass: A precision-machined titanium bezel frame absorbs heavy impact, while the aluminosilicate glass lens defends against scratching and extreme pressure.
- Air Integration for Up to 4 Transmitters: Track multiple cylinders simultaneously for complex sidemount, twinset, or multi-stage bailout gas planning.
- User-Replaceable AA Battery Power: Operates on standard AA batteries (Energizer Ultimate Lithium recommended) for quick field swaps on remote dive expeditions without proprietary chargers.
- Haptic Vibration Warnings: Customizable wrist vibration alerts ensure critical depth, time, ascent rate, and decompression notifications are clearly felt through heavy exposure suits.
- 3D Digital Compass: Integrated 3-axis tilt-compensated digital compass with heading lock for precise underwater navigation.
- Multi-Mode Decompression Algorithm: Driven by the Bühlmann ZHL-16C algorithm with customizable Gradient Factors supporting Air, Nitrox, 3-Gas Nitrox, OC Technical Trimix, CCR, and Gauge modes.
