Shearwater Peregrine TX vs Perdix vs Teric: Which Dive Computer Is Right for You?

Brent Clevenger   Aug 09, 2026

If you are comparing the Shearwater Peregrine TX, Perdix, and Teric, the good news is there is no wrong answer — all three are excellent, rugged, and share Shearwater's clear, no-nonsense interface. The real question is which one fits the diving you do now and where your training is headed. Here is how we help divers choose at our shop.

The Short Version

  • Peregrine TX — the best value for most recreational and advancing divers who want a big screen, wireless air integration, and a compass.
  • Teric — for the diver who wants a premium, watch-style computer they can wear every day, with full technical capability.
  • Perdix (2 and the new Perdix 3) — the full-size, do-anything computer for serious recreational and technical divers who want the largest, most readable display.

Shearwater Peregrine TX

The Peregrine TX takes the hugely popular Peregrine and adds the two features divers most often come back for: wireless air integration and a digital compass. It has a large, bright color screen and Shearwater's famously simple menus. For a diver moving through Nitrox, navigation, and deeper diving, it is often the sweet spot of capability and value.

Best for: recreational and advancing divers who want room to grow without paying for full technical features.

Shearwater Teric

The Teric packs advanced dive-computer capability into a watch-style body you can wear all day. It supports air integration, multiple gases, and technical dive modes, so it grows with you from recreational into technical diving — all in a package that does not look like a dive computer on land. Available in black and silver.

Best for: divers who want premium capability in a compact, everyday-wearable form.

Shearwater Perdix (2 and 3)

The full-size Perdix is the choice when screen size and readability matter most. The proven Perdix 2 and the newest Perdix 3 — with its larger, ultra-bright AMOLED display — are built for serious recreational, technical, Trimix, and rebreather divers. If you already know your training is headed into decompression or mixed-gas diving, this is the platform to grow into. Ask us about Perdix 3 availability; we have units on the way.

Best for: serious recreational and technical divers who want the biggest, most rugged display.

Do You Need Air Integration?

All three support Shearwater's wireless air integration with the Swift transmitter, which sends your tank pressure straight to the computer. If you like a clean, single-device setup, it is worth adding.
