Shearwater Peregrine

At a glance

The Peregrine puts the Bühlmann ZHL-16C algorithm with configurable gradient factors behind a two-button interface and a 2.2 inch full-colour transflective display, rated to 200 m. It charges over USB-C with a AA backup option and syncs to Shearwater Cloud over Bluetooth. Air integration is available through an optional transmitter rather than built in.

Where it wins and where it costs you

Full review: Shearwater Peregrine

Shearwater built the Peregrine as the entry point to its range, and the important detail is what did not get cut. The decompression engine is the same Bühlmann ZHL-16C with configurable gradient factors that technical divers run on the Perdix, and the screen is the same 2.2 inch full-colour transflective panel that stays readable in bright sun and in murky water. Depth rating is 200 m, far past anything a recreational diver will use, which means the housing is not the limiting factor.

What was simplified is the interface. Two buttons drive the whole computer, which sounds limiting on land and turns out to be the right call underwater in gloves, where fewer choices means fewer mistakes. Display screens are customisable so no-decompression limit, depth, dive time or gas mix can take priority depending on how you dive. The firmware carries a predictive multi-gas and CCR-ready upgrade path, so the computer follows a diver into more demanding training instead of being replaced at the first course.

Power comes from a rechargeable lithium-ion cell over USB-C, with a single AA as a swappable backup — a sensible hedge for trips where mains power is unreliable. Bluetooth syncs logs to Shearwater Cloud and delivers firmware updates. Air integration is supported but the transmitter is a separate purchase, so budget for it if tank pressure on the wrist matters to you. The physical caveat is size: the puck form factor is bulky on smaller wrists, and there is no way around that.
