Browse All GuidesThe Shearwater Peregrine TX is the Peregrine for divers who want their tank pressure on their wrist. It takes everything that made the standard Peregrine the default recreational dive computer, the big readable colour screen and the trusted Buhlmann algorithm, and adds the two things it never had: wireless air integration and a digital compass. Buy the Shearwater Peregrine TX if you want air integration in a simple, recreational-focused computer without stepping up to a technical machine. If you do not need tank pressure on your wrist, the standard Peregrine does the diving identically for less, and my best dive computer guide lays out the full field.
One honest note before going further: the Peregrine TX is listed and shipping on Amazon US. There is no Amazon UK listing yet, so if you are diving from the UK, my best dive computer guide and the standard Peregrine review cover what you can buy today. For everyone who can get the TX, here is whether it earns the step up.
What It Actually Is
The Peregrine TX is Shearwater's air-integrated recreational dive computer, and the easiest way to understand it is as the bridge between the standard Peregrine and the technical Perdix 2. It keeps the Peregrine's 2.2-inch colour display, one of the most readable screens in the category, and runs the same Buhlmann ZHL-16C algorithm with adjustable gradient factors that Shearwater puts in computers costing far more. What it adds is the TX part: it pairs with Shearwater's SWIFT wireless transmitters, up to four of them, so you can see live tank pressure on your wrist, and it includes a tilt-compensated digital compass the standard Peregrine does not have.
It covers Air, single-gas Nitrox, three-gas Advanced Nitrox, and Gauge modes, which is the right spread for recreational and accelerated-nitrox diving without reaching into full technical territory. The one change that surprises Peregrine fans is the battery. Where the standard Peregrine runs on a field-replaceable AA cell, the TX is rechargeable, with an internal lithium-ion battery good for around 30 hours of dive time per charge. That is a deliberate trade, and whether it is the right one for you is the whole question this review answers.
The Case For It
The air integration is the headline, and it changes how a dive feels. With a SWIFT transmitter on your first stage, your remaining tank pressure sits on the same screen as your depth and your no-decompression limit. You stop alternating between a console gauge and your computer, doing mental arithmetic about gas and time as two separate problems. The TX puts them together, and on a multi-level dive or a drift where you are task loaded, that single integrated picture is genuinely calming. Supporting up to four transmitters also means it scales to sidemount or doubles if your diving goes that way, which is rare in a computer pitched at recreational divers.
Then comes the display, inherited straight from the Peregrine that earned the reputation. The 2.2-inch colour screen is large and clear, the kind you read at a glance in poor visibility with cold hands rather than squinting at. After years of dimmer dive-computer screens, that readability is the thing experienced divers point to first, and the TX keeps all of it. On a recreational dive computer, a screen this easy to read is a safety margin as much as a comfort.
Then there is the algorithm and the compass. The Buhlmann ZHL-16C model with user-configurable gradient factors is the standard in serious diving, and having it accessible on a recreational computer means the TX grows with you. You can run conservative defaults while you build experience and tune the gradient factors later, the right way round. The new tilt-compensated digital compass closes the standard Peregrine's most-requested gap, giving you a proper electronic heading for navigating a wreck or a reciprocal course without a separate instrument. Add the SWIFT support and the compass together and the TX is doing the work that used to need a console and a wrist compass, all on one device.
It is still a Shearwater, too, which counts for a lot. It connects to Shearwater Cloud over Bluetooth for dive logging and free firmware updates, and the company has a long track record of improving computers for years after you buy them. The recent V89 firmware, which I cover in the standard Peregrine review, brought a configurable mini-dashboard and support for up to four wireless transmitters to the whole line, the TX included. You are buying into an ecosystem that keeps getting better for nothing.
On The Dive
Underwater, the air integration is the part that changes the texture of a dive. Your gas, your depth, and your no-decompression limit all sit on one screen, and the TX is doing the gas-time maths so you do not have to. On a wall dive where you are drifting and watching for the next overhang, not having to break attention to read a console gauge is a real reduction in task loading. The big colour display carries that information clearly, and the new digital compass means a navigation leg is a glance at the wrist rather than a fumble for a separate instrument.
The mini-dashboard added in the V89 firmware suits the TX especially well, because air integration gives you more to show. You can keep tank pressure, NDL, and depth in view together rather than cycling between them, which is exactly what you want when the dive gets busy. The buttons work the same wet or dry, in gloves, at depth, with none of the touchscreen fussiness that catches some watch-style computers out. It behaves like a tool designed by people who dive, which is the consistent thread through every Shearwater.
Setting It Up
Getting the TX diving is straightforward. You thread a SWIFT transmitter onto your first stage high-pressure port, pair it to the computer once, and from then on your tank pressure appears automatically each time you gear up. Gas presets and gradient factors are set on the surface and sync to Shearwater Cloud, so you configure the computer once and forget about it. The rechargeable battery tops up over a standard cable, and a full charge comfortably covers a normal diving day with the air integration running. None of it is fiddly, and that low-fuss setup is a big part of why the Peregrine line earns the loyalty it does.
The Honest Case Against It
The main drawback is the battery, and it cuts directly against what made the Peregrine famous. The standard Peregrine's field-replaceable AA cell is its single best party trick: no charging cable to pack, no power point to fight for on a liveaboard, and lithium AAs that you can buy in a petrol station and that handle cold water better than rechargeables. The TX gives all of that up for an internal rechargeable battery. For day-boat diving with reliable shore power, that is a non-issue. For remote trips, cold water, and liveaboards where charging is awkward, the standard Peregrine's battery is genuinely the more practical choice, and the TX asks you to trade it away for the air integration.
Then there is price and positioning. The TX costs meaningfully more than the standard Peregrine, and the entire reason to pay the difference is air integration plus the compass. If you are happy reading tank pressure off a console gauge, you are paying for a feature you will not use, and the standard Peregrine dives identically for less.
And it is not a technical computer. If your diving is heading toward trimix or closed-circuit rebreathers, the TX does not go there, and the Perdix 2 is the Shearwater built for that path. The TX is deliberately a recreational and accelerated-nitrox computer with air integration bolted on, and it is excellent within those limits. Buy it for what it is, not as a cut-price route into technical diving.
Who Should Buy It, and Who Shouldn't
Buy the Peregrine TX if you want wireless tank pressure and a digital compass in a simple, readable, recreational computer, and you mostly dive where charging is not a problem. It suits the diver who loves the Peregrine formula but always wished it showed air, and who would rather have one integrated screen than a separate console gauge.
Do not buy it if the field-replaceable AA battery is the reason you wanted a Peregrine in the first place. In that case the standard Peregrine review covers the model that keeps that advantage, and you give up only the air integration. Do not buy it if you are heading into technical diving either, where the Perdix 2 is the right Shearwater, and the [Shearwater Peregrine vs Perdix 2 comparison](/guides/shearwater-peregrine-vs-perdix-2) lays out that decision. And if you only want a basic recreational computer on a budget, the best dive computer guide has cheaper options that track your nitrogen just as safely.
Compared To The Obvious Alternatives
The names you will weigh against the TX are the standard Peregrine, the Perdix 2, and the air-integrated watches like the Garmin Descent Mk3i.
Against the standard Peregrine, the choice is air integration versus the AA battery. They share the same screen, the same algorithm, and the same easy character. The TX adds wireless tank pressure and a compass and goes rechargeable; the standard model keeps the field-replaceable battery and costs less. If you want air on your wrist, the TX. If the no-charging battery is your priority, the standard Peregrine.
Against the Perdix 2, the trade is recreational simplicity versus technical capability. The Perdix 2 is the trimix and rebreather computer, with the deeper feature set and the larger price to match. The TX is the recreational and accelerated-nitrox computer with air integration. If you are not diving trimix or closed-circuit, the Perdix 2 is more machine than you need, and the TX gives you the air integration most recreational divers actually want.
Against the Garmin Descent Mk3i, you are weighing a dive-first instrument against a true everyday smartwatch. The Mk3i puts air integration and SubWave diver messaging in a watch you also wear running and sleeping, and it costs accordingly. The TX is a dedicated dive computer with a bigger, simpler dive screen and no pretence of being a daily watch. If you want one device for everything, the Mk3i. If you want a focused dive computer with air integration, the TX is the cleaner, more readable tool.
What I'd Buy Today
If I wanted air integration in a simple, supremely readable recreational dive computer and I dived mostly where I could charge it, I'd get the [Shearwater Peregrine TX](https://www.amazon.com/dp/B0D45ZD2B5?tag=divegearadvice-20&ascsubtag=shearwater-peregrine-tx-review). It puts tank pressure and a real compass on the best screen in the class, runs the algorithm serious divers trust, and keeps getting better through free firmware. For the diver who always wanted the Peregrine to show air, this is the one.
If the field-replaceable AA battery is what drew you to the Peregrine, buy the standard model instead and keep that advantage. And if technical diving is where you are heading, the Perdix 2 is the Shearwater to grow into. Pick the one that matches how you dive, get it set up on Shearwater Cloud, and go diving.
