Swift GPS — GNSS transmitter for Shearwater air-integrated dive computers.

The Swift GPS captures dive entry and exit coordinates and adds map locations to your Dive Shearwater log. It works with Shearwater air-integrated computers to provide GNSS location data alongside real-time gas pressure information for accurate gas time-remaining calculations.

Key features

• Automatically capture dive entry and exit GPS coordinates and map dives in Dive Shearwater
• Provides real-time gas pressure data for air-integrated computers
• Any nearby Shearwater air-integrated computer can receive the Swift GPS signal
• If multiple transmitters are used, only one needs to include GPS
• LED status indicator and easy, tool-free installation on the first stage

Compatibility

• Compatible with all current Shearwater air-integrated dive computers
• Supported models include: Perdix 2, Petrel 3, Peregrine TX, Tern TX and NERD 2
• Teric support available in a subsequent firmware release
