The Petrel 3 combines a 2.6-inch AMOLED display with technical dive modes and a user-replaceable AA battery.
Why we’ve selected it
An option for divers who want a larger display for multigas and technical diving. We can help you choose around your current setup and future plans.
Fit and compatibility
Choose Standard, Fischer Connection or AK (4-Pin) carefully: an external connection must match your rebreather’s monitoring system. Contact us to check the exact connection before ordering. Transmitters are optional and sold separately. Vibration alerts require a supported battery type; Shearwater specifies 1.5 V non-rechargeable lithium or supported 3.7 V rechargeable lithium cells.
What’s included
Petrel 3 computer, webbing straps, screen protector and product information guide.
