A compact, watch-style colour dive computer for air and nitrox diving. The Tern focuses on the core dive information, without wireless tank-pressure monitoring.
Why we’ve selected it
This is an option for divers who prefer a smaller computer on the wrist for local diving and travel. If reading small numbers is a concern, we recommend comparing it with a larger-screen model before deciding.
Key features
Four-button controls and a colour AMOLED screen. Bluetooth log transfer, vibration alerts, updateable firmware and wireless charging.
Choosing your setup
Choose the TX model if you want wireless tank-pressure monitoring and a digital compass. These models support air and nitrox; for trimix or rebreather modes, we can help you choose a different computer.
What’s included
Tern computer, wireless charging station with USB-C cable, screen protector and product information guide. Remora quick-release band and an additional short band.
