Garmin Descent S1 Buoy
Meet the Garmin Descent S1 Buoy – a genuinely game‑changing innovation in dive safety and communication. This rugged smart buoy seamlessly links your dive group with your topside crew in real time, bringing greater situational awareness and stress‑free connection to every dive.
Packed with intelligent features, the Garmin Descent S1 Buoy bridges the gap between divers and the surface team. It enables real-time tracking of multiple divers, displays critical data like tank pressure and depth, and provides directional guidance to help divers navigate back to the buoy. With built-in GPS, two-way preset messaging, and seamless integration with the Garmin Dive™ app, it also offers post-dive heatmap analysis and easy wireless syncing. The result is a compact, reliable tool that enhances safety, coordination, and communication on every dive.
Features:
- Remote Diver Monitoring
Surface crews can monitor up to eight divers using compatible Descent dive computers paired with T2 transceivers, receiving real-time updates on tank pressure, depth, distance, and direction via the SubWave sonar network. Automatic alerts can notify topside if a diver approaches critical depth or tank pressure thresholds, helping ensure timely responses in case of potential issues.
- Two-Way Messaging
Using the Garmin Dive app, surface crews can send and receive preset messages to divers equipped with Descent T2 transceivers and compatible dive computers — allowing quick alerts in case of emergencies or important updates. Additionally, the Descent S1 Buoy helps boost the underwater communication range between divers, keeping teams better connected during the dive.
- Diver Location Tracking
Surface teams can view the approximate distance to each diver connected to the SubWave sonar network, with tracking possible up to 100 metres from the Descent S1 Buoy.
- Find My Buoy
Divers connected to the SubWave network can view both their distance and direction back to the Descent S1 Buoy, offering a reliable reference point and enhancing spatial awareness during the dive.
- Post-Dive Review
Once back on the surface, divers connected to the network can sync their dive data with the Garmin Dive app to view approximate underwater heatmaps, helping them visualise and review where they explored during the dive.
- Rugged Design
The Descent S1 Buoy is lightweight at under one kilogram, built tough with impact-resistant materials, and rated IPX8 for water resistance down to 10 metres.
