Shearwater Tern

Designed with the sport diver in mind, Shearwater’s new Tern dive computer is a powerful, simple, reliable, and compact watch-type computer. The Tern builds upon the success of the popular Shearwater Peregrine dive computer with an appearance similar to, yet lighter and thinner than, the Shearwater Teric. 

What differs it from the Shearwater Tern TX isn't just the silver bezel and buttons colour (as opposed to black) but that it's not transmitter capable, nor does it have a digital compass. Neither of the Tern models have OC mixed gas technical and CCR modes as do the Shearwater Perdix 2, Teric and Petrel 3.

Both the Tern & Tern TX are depth rated to 120 metres and tested to engineering EN standards for dive computer compliance. They both support Air, Nitrox, 3 Gas Nitrox, Gauge, and Freedive modes and can log 500 hours of dives with a battery life of 20 hours with dive mode on. 

Tern AMOLED screen

With a watch-style form factor, the 1.3” diameter AMOLED screen provides crystal-clear visibility in various lighting conditions, making it easier than ever for divers to keep track of their crucial information.

The vibrant, best-in-class high-resolution display offers Shearwater’s renowned user interface that provides divers with at-a-glance access to vital data, ensuring a safer and more enjoyable diving experience.
