The Shearwater Tern TX dive computer puts depth, dive time and compass heading on your wrist. Pair it with a compatible wireless transmitter, such as the Shearwater Swift, to view cylinder pressure on the same display. The standard Tern TX package includes a wireless charging station and two quick-release straps. The transmitter is sold separately.
Overview
The Shearwater Tern TX is designed for sport divers who want a compact wrist computer for air and nitrox diving. Its high-contrast AMOLED display makes dive information easy to read at a glance, while the tilt-compensated compass helps you check your heading even when your wrist is angled.
Choose from Air, Nitrox, 3 Gas Nitrox, Gauge and Freediving modes. The Tern TX supports up to three open-circuit gases in 3 Gas Nitrox mode. Compared with the standard Shearwater Tern, the Tern TX adds a built-in digital compass and optional wireless cylinder pressure monitoring.
