Frequently Asked Questions
Q: How does the Swift GPS transmitter log location data?
A: The Swift GPS transmitter utilizes GNSS constellations (GPS, Galileo, BeiDou) to record exact surface coordinates immediately before submerging and upon surfacing. When synced via Bluetooth to the Shearwater Cloud app, these waypoints automatically map your dive entry and exit points.
Q: How is the Tern TX charged?
A: The Tern TX features built-in wireless inductive charging. It includes a USB-C wireless charging station, eliminating the need for battery changes or exposed physical charging ports.
Q: What is the difference between the standard Tern and the Tern TX?
A: The standard Tern is a standalone dive computer without wireless transmitter capabilities or a compass. The Tern TX adds full wireless Air Integration (supports up to 4 transmitters) and a 3-axis digital compass.
