Reviews

Frequently Asked Questions?

What maitenence is required for the Tern TX?

Like all lithium batteries, the Tern should be charged prior to storage, and topped up every few months to ensure the battery is not damaged by being completely discharged. After-dive care includes thoroughly rinsing in clean water and storing it dry. Take care to avoid using high-pressure water to wash or compressed air to dry.

Are the Tern TX and Teric screens the same?

The AMOLED panel has the same fantastic brightness and color gamut. The Tern TX’s screen is 2.2 mm smaller in diameter compared to the Teric’s. Additionally, the Teric’s screen is bonded to the sapphire lens, which enhances light transmission and improves the viewing angle.

Does the Tern TX have smart watch features?

The Tern TX offers basic watch functionality and great looks, which is perfect for the surface interval and diving weekends. We do not include hybrid smart watch functions. Shearwater makes dedicated dive computers which are powerful, simple, and reliable. We believe that reliable and intuitive instrumentation underwater is critical to your enjoyment and safety. The underwater environment is not a place to read manuals or remember complex button pushes.

What algorithm does the Tern TX use?

Bühlmann ZHL-16C with gradient factors featuring preset conservatism settings of low, medium, or high. User-customized gradient factors are also possible. The Tern TX does not support additional algorithm unlocks such as VPM or DCIEM at this time.
