Shearwater Peregrine

If you want one computer that just works, this is the usual answer: huge clear display, the simplest menus in diving, and a colour screen at a mid-range price. Add the Swift transmitter later if you want air integration.

Do-everything flagship

Shearwater Perdix 2

One computer from your first reef dive to full trimix and rebreather diving. A big 2.2-inch screen, rock-solid Bühlmann GF algorithm and optional wireless air integration make it the long-term keeper.

Prefer everything on a hose? This air-integrated console packs depth, time, pressure, gas time remaining and a digital compass into one rugged cluster with a choice of two algorithms.

Shearwater Swift transmitter

Turn a Peregrine TX, Teric or Perdix 2 into an air-integrated setup. The Swift sends tank pressure and true gas-time-remaining to your wrist, with a quick LED battery check before you splash.

A dive computer is life-support equipment

The reviews and guides here are editorial information to help you compare models — they are not dive training or a substitute for proper certification. Always dive within the limits of your training, follow your computer's ascent rate and stops, and get formal instruction before technical, nitrox, trimix or rebreather diving.
