Tern – Compact Full-Color Recreational Dive Computer

The Shearwater Tern is a compact, lightweight recreational dive computer built around Shearwater’s signature clarity, ease of use, and high-visibility colour display. Designed for divers who want a smaller wrist presence without sacrificing performance, the Tern delivers clean dive data, intuitive navigation, and dependable operation in a travel-friendly form factor.

Its bright AMOLED screen provides crisp readability in sunlight, shadows, and low-visibility environments, while the simple two-button interface makes mode changes and underwater navigation fast and predictable. The Tern is ideal for new divers, travelers, and anyone wanting a streamlined computer that still supports multi-gas nitrox and decompression capability.
