Product Information

The Shearwater Tern TX is a compact watch-style recreational dive computer with wireless air integration, built around a 1.3 in (3.3 cm) full-color AMOLED display at 360 x 360 resolution and rated to 120 m / 394 ft. It pairs with up to four Shearwater wireless transmitters and adds a 3-axis tilt-compensated digital compass, so a single 50 mm wrist unit shows depth, time, tank pressure and heading.

Who it is for

It suits recreational and light technical divers who want tank pressure on the wrist instead of a hose-mounted gauge, and who also wear their computer as an everyday watch. With Air, Nitrox, 3 Gas Nitrox, Gauge and Freediving modes, plus Avelo Mode through an optional unlock code, it covers single-tank recreational diving, multi-gas nitrox dives, breath-hold sessions and Avelo System diving. It can also monitor up to four transmitters at once.

Frequently Asked Questions

Which transmitters work with the Shearwater Tern TX?

The Tern TX pairs with Shearwater wireless transmitters, including the Swift and the Swift GPS. It can connect with up to four transmitters at once, which lets you monitor multiple cylinders on a single screen. Transmitters are sold separately. If you are unsure which Swift version fits your regulator setup, call 888-701-4017 and we will confirm before you order.

How long does the Tern TX battery last and how do you charge it?

The internal 1.33 Wh rechargeable lithium-ion battery delivers up to 20 hours of dive time at medium brightness and roughly 6 months of standby. Charging is wireless and inductive using the charging station and USB-C cable included in the box.

What is the difference between the Tern TX and the standard Tern?

The Tern TX is the air-integrated version of the Tern watch-style dive computer. It adds wireless air integration for up to four transmitters so tank pressure appears on the wrist. The Tern TX is the air-integrated version of the Tern watch-style computer, adding wireless air integration for up to four transmitters so tank pressure appears on the wrist.

Will the Tern TX fit a small wrist?

Yes. The Tern TX uses a 22 mm quick-connect Remora band with a quick-release system, and Shearwater includes one short Remora band for smaller wrists in the box. The case itself is compact at 50 mm in diameter, 16 mm thick and 100 g, so it wears like a watch both in and out of the water.

Review summary

4.9 49 ratings across the web

Reviewers consistently describe the display as crystal clear and easy to read in both dark and bright water, and they like being able to configure what shows on the main screen. The built-in compass, dive logging through the app, and support for multiple transmitters, including older legacy ones, come up repeatedly. Battery life holds up across dives and a week of watch wear. One diver found the buttons stiff and the strap prone to scratching. It suits recreational divers who want a readable, configurable air-integrated computer that also works as a daily watch.

Great computer

Loved this dive computer! Got it to upgrade from an Oceanic Veo 200, and very glad that I did. Paired it with the Swift GPS TX, and it worked great on my dive vacation to track multiple days of diving seamlessly.

Great quality and very intuitive

Great quality and very intuitive. The feature set is fantastic and I love how the application logs your dives. I’m overall extremely happy with this computer.

Excellent wetsuit but will it crush quickly like other wetsuits?

I purchased a BARE 5mm Reactive wetsuit (open box), which was like new, to replace my 1.5 yr old BARE 5mm Velocity wetsuit which had collapsed to only 2.5mm after 3 diving trips (~100 dives). The Reactive wetsuit is well constructed and very flexible. I had to increase the size of the Reactive suit, as it was smaller than the BARE Velocity suit of the same size. Tremendous customer service by Dive Catalog to exchange the wetsuit for proper size. I hope the Reactive suit does not crush so quickly like my other wetsuits (BARE, Henderson, Pinnacle). Hoping that the new technology in this suit will keep me warm below the thermocline.

Perfectly Built

Best of the many many diver hangers in my life. Easily supports my steel-plated BCD, while still donned with all of my accessories. No cracks, bends, or dents. Has even supported my BCD w/ a steel 100 tank attached (not recommended, for safety purposes, though).

Will continue to use this hanger for the long-term. No brainer.

Go-to Dive Hanger

This is a must-have for every diver. It's the quintessential hanger for all dive gear in one small package.

DiveCatalog's "Quick Dry Multi Accessory Dive Gear Hanger for Boots, Gloves, Hood" is set at a great price for a great product. Versatile enough that I've purchased extra hangers to organize my BMX racing gear.

Must-have for divers and anyone looking to organize their adventurous outdoor activities equipment.

Solid Hanger w/ Tons of Options

Does it's job and then some. The added accessory arms gives you options for a multitude of storage solutions. Solid build, solid pricing, must have for owns of dive gear.

New to this hanger...Now I'm a believer

Used tons of dive hangers, but never an upside down hanger. Game-changer for me. Will now add more of these in the near-future.

With it's swivel head design, it can cram itself into my tight dive locker, while still donning a ton of gear.

DiveCatalog's "Upside Down Drysuit Hanger w/ Regulator and Accessory Hooks" is a great product with solid construction at an affordable price. All of that with Dive Catalog's customer support/satisfaction guarantee.
