Shearwater Tern Dive Computer

Shearwater Tern Dive Computer

The Shearwater Tern is made for divers who want a smaller, watch-style computer without giving up the features that make Shearwater so easy to dive. The bright 1.3” AMOLED color display is crisp and readable, and the interface stays simple and intuitive—so you spend less time clicking through menus and more time focused on the dive.

Under the hood, the Tern runs Advanced Nitrox using Bühlmann ZHL-16C with configurable Gradient Factors, which gives you the flexibility to keep things straightforward or dial in conservatism the way you prefer. It supports Air, Nitrox, 3-Gas Nitrox, Gauge, Freedive, and Timepiece modes, making it a strong everyday computer for travel, training, and regular recreational diving. 

The wireless rechargeable battery keeps charging simple, and Bluetooth connectivity makes it easy to sync dives after you’re out of the water. If you want a clean, modern dive computer that wears like a watch but feels like a Shearwater, the Tern fits the bill.
