Shearwater Tern TX Dive Computer Swift Transmitter

Shearwater Tern TX with Swift Transmitter is an outstanding sport diving computer designed for those who prefer a comfortable, lightweight, multipurpose round-faced watch format that can be worn underwater and on the surface.

When paired with the Swift Transmitter, the Tern TX provides a world-class transmitter-enabled system enhanced by a digital compass for underwater navigation, all at an attractive price.

Similar in appearance to the technically focused Shearwater Teric, the Tern TX shares its sleek design but is thinner.  Unlike its "Silver outlined" standard sibling, the Tern, the Tern TX includes air integration and a digital compass.

High Resolution Amoled Display

With a watch-style form factor, the 1.3” diameter AMOLED screen of the Tern TX 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.

Swift Transmitter - Air Integration

The transmitter enables you to receive real-time gas pressure data and provides accurate calculations of remaining gas time for extended dives. You can easily view all dive metrics on one screen, enhancing your underwater adventure and enjoyment. 

With smart AI technology, the Swift creates a highly reliable connection, listens for other transmitters, and only communicates when the channel is clear by avoiding collision with other signals.

Now, divers can use multiple transmitters near each other without worrying about potential interference.

A double o-ring seal protects a user-replaceable 3v CR2 lithium battery, operating up to 300 hours. The LED status indicator lets the diver know things are functioning as they should at a glance during setup.

Digital Compass

The Tern TX's built-in digital compass provides clear headings to keep you on track during your dive, and the reciprocal heading assists you in returning to your starting point effortlessly. With the Tern TX, underwater navigation has never been more straightforward.

Dive Modes

The Shearwater Tern TX is ideal for decompression and no-decompression diving, and multiple recreational dives with Shearwater's tested and proven reliable algorithm working in the background. You'll be able to use this dive computer with 5 modes: Air, Nitrox, 3 Gas Nitrox, Gauge and Freediving.
