This package puts the Shearwater Tern TX dive computer together with its matching Swift transmitter, giving you a complete wrist-mounted air integration system in one purchase. The Tern TX pairs wirelessly with up to four transmitters and puts tank pressure right on its 1.3-inch (3.3 cm) full-color AMOLED display, while running the Buhlmann ZHL-16C algorithm with gradient factors across Air, Nitrox, 3 Gas Nitrox, Gauge, and Freedive modes. The Swift transmitter threads onto a standard 7/16-inch-20 UNF high-pressure port with no tools required, and its advanced collision avoidance system keeps pressure readings reliable even when other divers nearby are running their own transmitters.
Both devices are built for regular use in the water. The Tern TX is depth rated to 120 m / 394 ft with a ballistic nylon polymer case and 316 stainless steel bezel and buttons, and its internal rechargeable lithium-ion battery runs up to 20 hours at medium brightness on a charge from the included wireless charging station and USB-C cable. The Swift is rated to 200 m of seawater and a 300 bar / 4350 psi working pressure, and runs on a user-replaceable CR2 lithium battery good for up to 300 dive hours with high pressure present.
Rounding out the package, the Shearwater EVA Case gives the computer a padded, zippered home for travel and storage between trips, with a ballistic nylon exterior and anti-shock EVA interior sized for the Teric, Perdix, Petrel, Peregrine, and Tern family. The Tern Screen Protector Kit adds two die-cut clear PET film protectors sized specifically for the Tern and Tern TX display, along with the microfiber cloth, dust absorber sticker, dry and wet wipes, and squeegee needed for a clean, bubble-free application.
