SONAR COMMUNICATION: YOUR DEEPER CONNECTION
The Garmin Descent™ S1 Buoy brings Garmin’s SubWave™ sonar network to the surface, helping dive teams stay connected above and below the water. Topside crew can monitor compatible divers, exchange preset messages and track approximate diver distance, while networked divers can navigate back toward the buoy for an added return-to-base reference.
Key Features
- Monitor up to 8 divers: Surface crew can view compatible divers’ tank pressure, depth, distance and other dive data in the Garmin Dive™ app when each diver is using a compatible air-integrated Garmin dive computer and Descent™ T2 transceiver.
- Two-way preset messaging: Exchange preset messages between the surface and compatible divers.
- Extended SubWave range: The buoy can extend underwater SubWave communication up to 100 m (328 ft) line of sight.
- Find My Buoy: Connected divers can view distance and direction back to the Descent S1.
- Post-dive heatmaps: Review approximate underwater movement after the dive in the Garmin Dive app.
- Up to 15 hours of battery life: Built-in rechargeable lithium-ion battery supports long dive days and weekend use.

- Surface connectivity: Wi-Fi® connection to the Garmin Dive app up to 60 m (197 ft), plus Bluetooth®, ANT® and SubWave connectivity.
