Product Information
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.
- Wireless air integration Tern TX connects with up to 4 transmitters to display tank pressure from compatible Shearwater wireless transmitters.
- AMOLED display 1.3-inch (3.3 cm) full-color screen with 360 x 360 resolution and 350 nit typical brightness.
- Proven algorithm Buhlmann ZHL-16C with gradient factors for reliable decompression information.
- 120 m depth rating Tern TX is rated to 120 m / 394 ft for recreational and light technical diving.
- Collision avoidance Swift's advanced collision avoidance system ensures reliable tank pressure transmission when multiple transmitters are in use.
- Tool-free installation Swift installs and removes by hand on a 7/16-inch-20 UNF high-pressure port.
- User-replaceable battery Swift's standard CR2 3V lithium battery delivers up to 300 dive hours with high pressure present.
- Travel protection The EVA Case combines a ballistic nylon exterior with anti-shock EVA padding to protect the computer during transport and storage.
- Precise-fit screen protection The Screen Protector Kit includes two PET protectors die-cut for the Tern and Tern TX, plus a full application kit.
- Matched system Computer, transmitter, case, and screen protection are sized and built for each other, so there is no guesswork on fit or compatibility.
