The device supports a depth rating of 200 metres and operates within an ambient temperature range of +4 °C to +34 °C (with short‑term tolerance from ‑10 °C to +50 °C).

Shearwater Issues Important Notice for All Tern and Tern TX Users

A serious issue has been identified with Tern and Tern TX v34 firmware. A fix is coming Monday April 14th, but in the meantime, it is important to take a precautionary measure.

Equipment
Shearwater Research


The issue is that if using Air mode and the Nitrox mode gas has been programmed to something other than air (21%), then that programmed gas is used while diving. This could result in a less conservative dive plan than is appropriate.

Prevention: If using firmware v34, do not use single gas Air Mode. Instead, use the single gas Nitrox Mode with 21% gas programmed.

Updated firmware for Tern and Tern TX will be released Monday April 14, 2025. Please check our website for the newest version.

Shearwater Tern TX Review

The Tern TX is the middle model in Shearwater’s “watch series” of dive computers. The series includes the little brother Tern and the big brother Teric. Tern TX is a dive computer for more advanced sport diving, up to advanced nitrox. 

Equipment
Shearwater Research

It has five different modes/dive methods plus an everyday clock:

• Air: For regular sport diving with air.
• Nitrox: For regular sport diving with a nitrox mix.
• 3 Gas Nitrox: Decompression diving with three different gas mixes of air and nitrox.
• Gauge: A bottom timer that only records time and depth.
• Freediving: For snorkelling and freediving.

The computer is approved for depths up to 120m, which should be sufficient.
