In 2025, Shearwater gave me the opportunity to test the Peregrine TX on 50+ dives.

Similarily to the Shearwater Teric which I also reviewed, while I really enjoyed using this dive computer, it didn't find a permanent spot on my wrist.

I'll explain why in this review.

The Peregrine TX is not trying to be a smartwatch.

It's a big, clear, premium wrist style entry level dive computer with air integration and a compass built in for $400 less than the Teric.

If you want reliable Shearwater technology underwater without paying a fortunte, I really think the Peregrine TX is worth a serious look.

A Few Disclaimers

Shearwater loaned me this computer for testing in 2025.

I did not purchase it but no payment was exchanged for this review.

I sent the computer back after completing my testing.

Prior to the Shearwater Peregrine, I had used the Shearwater Teric for one year, and a Suunto Zoop Novo beforehand.

How It Performs Underwater

The Peregrine TX uses the same Bühlmann ZHL-16c algorithm Shearwater runs across their entire lineup.

It will also very clearly display depth, NDLs, ascent rate, safety stops, like any other dive computer.

Where it begins to differntiate itself is first seen in the display.

At 2.2 inches it's significantly larger than any watch-style computer.

I've got pretty good vision, and don't need that extra screen real estate, so I prefer a watch style computer, but for many of you, the extra screen size can be invaluable.

Navigation is two buttons with the left cycling menus and the right action as a confirm. The device isn't touch screen.

3 Things I Loved

#1 — The Display

The screen is the single biggest advantage the Peregrine TX has over watch-style computers.

If you've ever struggled to read a smaller dive computer at depth or in low viz, this solves that problem immediately.

It's not as refined as the Teric's AMOLED, thecolors aren't as vibrant and contrast isn't as sharp, but in actual diving conditions underwater it's excellent.

You can also customize what data displays on the main screen.

#2 — Battery Life

On a dive vacation to Kona, Hawaii I lost the charging pad at the start of the trip. The Peregrine TX held its charge for over two weeks of diving without issue.

Passive drain in standby is minimal.

In practice I charged it roughly every few weeks diving regularly in South Florida and never came close to running out.

#3 — Value for the Feature Set

Air integration and a digital compass at $760 is pretty rare across dive computer, let alone Shearwater's Tech.

Both features are typically found on computers well above this price point.

The Peregrine TX brings them down without cutting corners on core dive functionality or the Shearwater algorithm that experienced divers trust.

2 Things I Didn't Like

The Wireless Charging Pad

The charging pad connects via proximity and doesn't hold on tight enough when you're moving.

On a boat, in a car, or in a packed gear bag it gets knocked loose constantly. Lose the pad in the field and you're not easily replacing it mid-trip.

It's a frustrating design choice for equipment built for travel.

The good news is battery life is strong enough that you won't need to charge it often but when you do, it's an annoyance.

It's Too Big for Everyday Wear

‍

This is the trade-off for that large display. The Peregrine TX is bulky on the wrist and not practical as an everyday watch.

If you're fine with a dive-only computer, this doesn't matter at all.

But if you want one device on your wrist around the clock, this isn't it.

Look at Shearwater's Teric, or the Garmin Descent MK3i (my personal dive computer).

Battery & Charging

Battery life lasts around 30 hours in dive mode. The passive drain in standby mode for me was low enough to go weeks between charges with regular diving.

Charging is wireless via magnetic pad over USB-C.

Air Integration

The Peregrine TX pairs with Shearwater's SWIFT wireless transmitter to display tank pressure, gas time remaining, and SAC rate directly on the watch face.

For me, the pairing was straightforward and doesn't require a manual.

The computer supports up to four transmitters, which covers sidemount and multi-tank setups.

The transmitter is sold separately, so expect around ~$1,100 total if you want the computer and air integration.

Shearwater Peregrine TX vs. Shearwater Teric

Display — Peregrine TX wins on size, Teric wins on quality. The Teric's AMOLED is sharper and more vibrant. Both are excellent underwater.

Dive functionality — Comparable for recreational diving. The Teric adds technical and rebreather modes the Peregrine TX doesn't have. For pure recreational diving the gap is minimal.

Wrist profile — Teric wins decisively. It's watch-sized and wearable all day. The Peregrine TX is wrist-only.

Price — Peregrine TX wins significantly. ~$760 vs ~$1,100+ for the Teric is a real gap, especially if dive functionality is your only criteria.

Who should buy the Peregrine TX — Recreational divers who want air integration and a compass, prefer a large readable display, and don't want to spend Teric money.

Who should buy the Teric — Divers who want the best pure dive computer in watch form, plan to wear it daily, or want technical dive modes.

Conclusion

The Shearwater Peregrine TX is a fantastic premium, wrist style dive computer for recreational divers. The display is huge and clear underwater, battery life is excellent, and the ability to air integration and have a digital compass at this price point is rare.
