Product Information
The Shearwater Swift GPS Transmitter is a wireless air integration transmitter with a built-in GNSS receiver that captures a dive's entry and exit coordinates at the surface while transmitting real-time tank pressure to any current Shearwater air-integrated dive computer. It is depth rated to 200 m, installs with no tools on a 7/16" -20UNF high-pressure port, and works exclusively with the Dive Shearwater app.
Who it is for
It suits divers already using a Shearwater air-integrated computer who want tank pressure and gas time remaining on the wrist plus an automatically mapped dive log. Because GPS signals do not pass through water, the transmitter needs a strong satellite fix just before descent and again after surfacing, so it is built for boat, shore and surface-interval logging of where a dive actually started and ended. A collision avoidance system lets multiple transmitters be used together, which helps on buddy and team dives.
Key details
- Depth limit 200 m, rated air pressure 300 bar / 4350 psi, HP port proof pressure 450 bar / 6525 psi
- Pressure reporting resolution 0.14 bar / 2 psi, accuracy 5% full scale, reporting interval 4.8 to 5.2 seconds
- GNSS on GPS L1C/A, Galileo E1B/C and BeiDou B1I, 2 m location resolution and 4 m accuracy (condition dependent)
- Transmission range approximately 3 ft (1 m); GPS status indicator appears on the dive computer when a valid fix is received
- User-replaceable CR2 3V lithium battery, up to 100 dive hours or 2 years storage
- 76 mm (L) x 34 mm (D), 135 g, operating temperature +4°C to +34°C
Compatibility and sizing
The Swift GPS works with Perdix 3, Perdix 2, Perdix AI, Petrel 3, Peregrine TX, Teric, Tern TX and NERD 2, and requires the latest firmware on the dive computer. It threads into a 7/16" -20UNF high-pressure port on a first stage regulator. Data and maps are viewed in the Dive Shearwater app only; it is not compatible with Shearwater Cloud.

Frequently Asked Questions
Does the Swift GPS track my position underwater?
No. GPS does not work underwater, so the Swift GPS records position only at the surface. It needs a strong satellite fix just before descent and again after surfacing, which is what lets it capture the dive's entry and exit coordinates. A GPS status indicator appears on the dive computer when a valid fix has been received, so you know the point was captured before you go down.
Which Shearwater dive computers work with the Swift GPS?
It works with all current Shearwater air-integrated dive computers: Perdix 3, Perdix 2, Perdix AI, Petrel 3, Peregrine TX, Teric, Tern TX and NERD 2. The dive computer must be running the latest firmware for the GPS features to function. Transmission range is approximately 3 ft (1 m) between the transmitter and the dive computer.
Can I use Shearwater Cloud with the Swift GPS?
No. The Swift GPS works exclusively with the Dive Shearwater app, which is where the captured coordinates and the maps added to your dive log are viewed. Shearwater Cloud is not compatible with the GPS data from this transmitter, so plan on using the Dive Shearwater app to download logs and see your entry and exit points on a map.
What battery does it use and how long does it last?
The Swift GPS uses a single user-replaceable CR2 3V lithium battery with a capacity of about 2.55 Wh, and Shearwater recommends the Panasonic CR2 Industrial Lithium cell. Battery life is up to 100 dive hours, or about 2 years in storage. The cover is secured with 1.5 mm hex 316 stainless screws, and the transmitter uses a 24 x 1.5 mm body o-ring.
Review summary
Reviewers agree this transmitter pairs quickly with Shearwater computers like the Peregrine TX, Perdix and Nerd 2, and puts tank pressure and real time gas consumption on the wrist. Divers running two transmitters on rebreather or sidemount rigs report no data clashes and few dropouts. Good to know: one diver saw brief connection drops that cleared in seconds, and the battery is user replaceable. It suits Shearwater owners moving to air integration, and divers who need several transmitters tracked at once.
