The Peregrine TX is the computer most divers settle on after outgrowing a wrist watch model. It gives you the full Shearwater interface — the same one used on their technical computers — without the technical price or the configuration burden. Everything is on one screen, in color, laid out so you can read your no-decompression limit at a glance in bad viz.
The included transmitter is what makes this a genuine upgrade rather than a nicer display. You get tank pressure on the same screen as your depth and time, plus gas time remaining calculated against your actual breathing rate, which is far more useful than a pressure number alone.

Went from a wrist computer with no AI. Seeing actual gas time remaining instead of doing pressure math at depth is the entire value. Transmitter paired in under a minute and has not dropped once in 40 dives.

Bought it for cold, dark water. Screen is bright enough at 30 m in 3 m viz without cranking brightness and killing the battery. Bungee kit is worth adding if you dive dry.

No battery to swap on a liveaboard means you need the pad and power. Not a problem on a boat with outlets, worth thinking about for remote trips. Otherwise it is the best screen I have used.

Yes, on the TX configurations. The computer-only option is the same unit without a transmitter, and you can add one later — it pairs to the same computer.
It supports air, nitrox up to three gases, and gauge mode, but it is not a trimix or closed-circuit computer. If you are heading into technical training, look at the Perdix or Teric instead.
Two years against manufacturer defects, processed by us as an authorized dealer rather than sending you to the brand. Flood and impact damage are not covered unless you add accident protection.
Bring or ship it to us. We diagnose, handle the warranty claim, and loan you a computer for a booked trip if the repair runs long.
