Descent S1 Buoy is a revolutionary addition to the Garmin dive lineup that helps strengthen diver communication and enhances peace of mind for divers and crew. Using Garmin’s unique SubWave™ sonar networking, the buoy integrates seamlessly with Garmin dive computers to help crew members on the surface track and monitor up to eight divers—and exchange preset messages with those using a compatible dive computer and Descent T2 transceiver. For increased situational awareness, connected divers can also see the distance and direction to the buoy and receive clear guidance to help them know where to surface.
