How we calculate scores →About this gear
A compact, round dive computer with a 1.3-inch AMOLED display and four-button operation. Its air, nitrox, three-gas nitrox, gauge and freediving modes sit alongside vibration alerts and a rechargeable battery. Quick-release straps include a shorter option.
Consider before buying
The standard Tern does not include wireless air integration or a digital compass. Compare with Tern TX if those are priorities; try the compact display in person to assess readability.
Our take
Tern makes sense as a model to compare if you want a compact recreational computer and do not need tank pressure or a compass on the wrist. Those omissions are the main reason to look at Tern TX instead. The 1.3-inch screen and four-button layout deserve an in-person check: a smaller case is only an advantage if the information remains comfortable to read. Compare the larger Peregrine if display area matters more than a watch-shaped body. Wireless charging is convenient only if you can bring and use the correct charging equipment on your trip. The source does not support treating Tern as a general sports smartwatch or a substitute for the technical modes of other models. Published narrative review evidence is linked below, but we have not verified an eligible numeric overall rating; there is no defensible score to display yet.
