Shearwater Tern Dive Computer The Shearwater Tern dive computer is a powerful, simple, reliable, and compact watch-type computer designed with the sport diver in mind. 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. The difference between the Tern and the Shearwater Tern TX isn't just the silver bezel and button colour (as opposed to the TX's black), but also that the Tern (non-TX) isn't transmitter-capable and doesn't have a digital compass. Neither Tern model has OC "mixed gas" technical and CCR modes as do the Shearwater Perdix 2, Teric and Petrel 3. However, both support Air, Nitrox, 3-Gas Nitrox, Gauge, and Freedive modes with 500 hours of log time, which is plenty for most divers. The Tern & Tern TX are each depth-rated to 120 metres and tested to engineering EN standards for dive computer compliance. High Resolution AMOLED Display With a watch-style form factor, the 1.3” diameter AMOLED screen of the Tern 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 features Shearwater’s renowned user interface, giving divers quick access to vital data for a safer and more enjoyable diving experience.
