Garmin Descent™ S1 Buoy

Elevate dive safety and communication with the Garmin Descent™ S1 Buoy. This rugged, compact diver communication buoy uses SubWave™ sonar networking to allow surface crew to monitor up to eight divers' tank pressure, depth, and location (up to 100m underwater). It enables two-way preset messaging between the surface and divers, and extends diver-to-diver communication. With GPS for surface tracking, 15-hour battery life, and post-dive heatmap review via the Garmin Dive app, it's an essential tool for dive teams, instructors, and serious enthusiasts.
