How we calculate scores →About this gear
The Petrel 3 is a large rectangular computer with a 2.6-inch AMOLED screen, titanium bezel and replaceable AA battery. It supports vibration alerts and up to four wireless pressure transmitters. Its screen size makes it worth comparing with the smaller-display Perdix models when wrist readability is the main buying priority.
Consider before buying
Petrel 3 is a family with standalone and rebreather-connected versions. Confirm the exact variant; a standalone purchase does not include a rebreather interface. A review of a wired CCR handset cannot establish the performance or compatibility of every Petrel 3 configuration.
Our take
The large screen and replaceable battery are concrete reasons to shortlist the standalone model. Compare the Perdix 3 on your own wrist before accepting the extra size. A Cave Diving Adventures review discusses a CCR-connected unit, so it has been recorded as related evidence rather than imported as an exact standalone review or score.
