Recreational Diving Meets Everyday Style

Key Features
- Compact 1.2″ AMOLED display for bright, full-color visibility underwater.
- Recreational dive modes including Air, Nitrox, Gauge, and Freediving.
- Wireless Qi charging with rechargeable battery convenience.
- Bluetooth connectivity for syncing dive logs with Shearwater Cloud.

Step Up to the Tern TX
Choose the Tern TX model to add wireless air integration in the same compact watch-style body. Pair it with a Swift or Swift GPS transmitter (add one above) to monitor tank pressure and get real-time gas time remaining (GTR) right on your wrist—ideal for recreational divers who want air integration without carrying a larger computer.
Best Fit
The Tern is a strong fit for recreational divers, Nitrox divers, and travel divers who want Shearwater reliability in a compact wrist computer. It is especially useful for divers who want one computer they can pack easily, read clearly, and keep on between dives.
