Garmin Descent™ S1 Buoy: Sonar Communication for Your Dive Team

Bridge the communication gap between the surface and the world below with the Garmin Descent™ S1 Buoy. This advanced sonar communication system creates a powerful network, allowing a surface crew to monitor, track, and exchange preset messages with their dive team underwater, fundamentally enhancing dive safety and coordination.

The SubWave™ Sonar Network:

The S1 Buoy is the hub of the Garmin dive ecosystem. When used with divers wearing compatible Garmin dive computers and Descent™ T2 transceivers (sold separately), it uses SubWave™ sonar technology to create a robust connection between the boat and the dive team up to 100 meters (328 ft) away.

For the Surface Support Crew:

This system provides an unprecedented level of oversight and communication for the team on the surface.

  • Monitor Your Divers in Real-Time: Using the Garmin Dive™ app, the crew can track key data like tank pressure, depth, and more for up to eight networked divers. Automatic alerts can notify the surface if a diver has an issue.
  • Send Messages Underwater: The app allows the surface crew to send preset messages directly to a diver's compatible wrist computer.
  • Track Diver Location: Monitor the approximate distance of each diver from the buoy.

For the Divers Below:

For the divers in the water, the S1 Buoy enhances situational awareness and communication.

  • Receive Important Updates: Get preset messages from the surface without having to end your dive. The buoy also extends the range of diver-to-diver messaging.
  • Always Know the Way Back: The "Find My Buoy" feature on a compatible computer shows the distance and direction back to the buoy, providing a clear return-to-base reference, which is invaluable in lower visibility or current.
  • Review Your Dive Path: After surfacing, you can review your underwater heatmaps in the Garmin Dive™ app to see approximately where you were exploring.

Built for the Field:

The rugged, impact-resistant S1 Buoy is water-rated to 10 meters (IPX8) and floats if dropped. Its internal rechargeable battery lasts for up to 15 hours of operation, and it connects via Wi-Fi® to the Garmin Dive™ app on the surface from up to 60 meters (197 ft) away. Multi-GNSS support (GPS and GLONASS) ensures accurate positioning on the surface.
