Shearwater is known for making some of the best dive computers on the market, and is most famous for their flagship Perdix 2.0. While the Peregrine lacks the bells and whistles needed for technical diving, it is still a highly functional dive computer for recreational divers. It has just the right touch of advanced features for those looking to explore light decompression diving.

Following the success of the Peregrine, 2024 saw the release of the Peregrine TX. This new model features both air integration and a digital compass, making it a serious contender for those who want a bit more flexibility in their diving.

Usability

Video

The common denominator for all the Shearwater computers is their intuitive menu. Peregrine and Peregrine TX’s two-button system makes it easy to scroll through and select/change the settings.

The display is large, bright, and easy to read, so even a quick glance underwater and you see it all very clearly. This is obviously a plus for those with impaired vision, but also for photographers or wreck divers who may need to quickly read information without trying to decipher a smaller watch face design.

The screen is fully customizable, allowing divers to adjust the font size, colors, and layout to their preference, which isn’t a common feature in entry-level computers.


The flagship Perdix 2 has the two-button interface, which the Peregrine has copied. It is intuitive, responsive, and easy to operate even when wearing thick gloves. Unlike other entry-level models, such as the Suunto Zoop, which can feel clunky to navigate, the Peregrine’s menu is refreshingly straightforward. The surrounding bezel clearly labels what each button does, eliminating any guesswork and ensuring quick access to settings and dive modes.

When recreational becomes technical

Shearwater Research has technical beginnings, so even its “recreational” dive computers— the Peregrines and the Ternssupport decompression diving. The Peregrine and the Peregrine TX each offer four dive modes: air, nitrox, gauge, and 3-gas nitrox.

The inclusion of a 3-gas nitrox mode is a welcome addition for those who want to dip their toes into planned decompression diving, as it allows divers to switch between multiple nitrox mixes, including up to 100% oxygen.

All Shearwaters use the Bühlmann ZHL-16C decompression model, a tried-and-true algorithm widely used in the diving community. The Shearwaters, Peregrines included, use gradient factors, allowing divers the flexibility to adjust how conservative or liberal their decompression profile should be. Divers can fine-tune their decompression strategy based on personal preference and dive conditions.

A 394-foot (120 m) depth rating is another technical feature of the Peregrines. Most recreational dive computers are limited to 196 to 330 feet (60 to 100 m), and not safe for decompression diving. This level of flexibility makes the Peregrine/TX much more adaptable than most other recreational dive computers, which tend to use fixed, one-size-fits-all safety settings.


Peregrine TX upgrades

The much-anticipated release of the Peregrine TX introduced a few notable upgrades that set it apart from its twin. Most significantly, the TX model is air-integrated, allowing divers to connect up to four Swift transmitters to monitor tank pressure. This feature is particularly useful for sidemount divers or those carrying multiple tanks, who can label each tank for easy reference.

Additionally, the TX includes a digital compass—a feature many divers appreciate for navigation. While some vacation divers may never need a compass, having one built in is always wise, and it removes the need to carry a separate, handheld unit.

Aside from these upgrades, the core functionality of the Peregrine TX remains the same as the original Peregrine, meaning divers still get the same intuitive interface, large display, and solid decompression model.


Price/Quality Ratio

The Shearwater Peregrine and Peregrine TX deliver exceptional value for money, standing out as some of the best-priced dive computers in their category.

Compared to similarly priced competitors like the AquaLung i470TC or the Suunto Zoop Novo, the Peregrine offers a far superior user experience with its intuitive menu system, bright full-color display, and customizable features.

The only truly comparable dive computer is the Garmin G1, which is the same price as the standard Peregrine. A pro is that it is also a fitness watch, but it has a monochrome display instead of the bright one you’ll find on the Peregrine.

If you’d like to upgrade to air integration, the Peregrine TX model with one transmitter is nearly double the price, but it still remains competitive compared to other air-integrated dive computers. The overall build quality and Shearwater’s excellent customer service make these models excellent investments for divers who want a high-quality computer that they can grow into.

Do we recommend the Shearwater Peregrine/TX?

Overall, the Shearwater Peregrine is an excellent dive computer for recreational divers who want a reliable, easy-to-use device that won’t break the bank. The Peregrine TX provides even more functionality, making it a great option for those who see themselves progressing in their diving journey.

If you’re unsure which model to choose, the TX is a safe bet—better to have air integration and never use it than to need it and not have it. Whether you choose the Peregrine or the Peregrine TX, you’re getting a well-built, highly capable dive computer from one of the most trusted brands in the industry.
