The Garmin S1 Descent Buoy revolutionises diver safety and communication, keeping your dive team connected via sonar — even below the waves. Designed to work seamlessly with the Garmin dive ecosystem, this advanced surface buoy allows topside crew to monitor tank pressures, depths, diver locations, and send preset messages through the Garmin Dive app. When paired with a compatible Descent T2 transceiver, divers can also view their distance and direction to the buoy for reliable return-to-base guidance.
Whether you're leading a group dive or diving as a buddy pair, the S1 Descent Buoy supports up to eight networked divers, providing a powerful sonar communication link and post-dive heatmaps for reviewing your underwater route. With up to 15 hours of battery life, it's the ideal companion for full-day adventures.
