Shearwater Tern TX Dive Computer Swift GPS 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.

Swift GPS Transmitter - Air Integration

Shearwater Research's Swift GPS Transmitter is engineered to provide divers with both reliable, real-time air integration and crucial surface location data, together with dive log maps. It represents a groundbreaking evolution of the trusted Swift AI technology into a single, compact, powerful unit.

While you'll enjoy all the features of the trusted Swift AI, receiving real-time gas pressure data and benefiting from accurate gas time remaining calculations for extended dive time, you'll also be getting a location accuracy of 4 metres based on a satellite reporting interval of 4.8 - 5.2 seconds.

Better still, if you already have a transmitter — or multiple transmitters —only one of them needs to be the GPS version to reap the benefits.
