Description
Advanced Surface Monitoring & Underwater Communication System
The Garmin Descent S1 Buoy is a revolutionary addition to the Garmin dive ecosystem, designed to enhance diver safety, communication and situational awareness. Combining advanced SubWave™ sonar networking, remote diver monitoring and two-way messaging capabilities, the Descent S1 allows surface support teams and divers to stay connected throughout the dive.
Working seamlessly with compatible Garmin Descent™ dive computers and Descent™ T2 transceivers, this innovative buoy provides real-time diver tracking, tank monitoring, underwater messaging and post-dive analysis, creating a comprehensive communication network both above and below the surface.
Real-Time Diver Monitoring from the Surface
The Descent S1 Buoy enables topside crew to monitor divers in real time while they are underwater. Connected through Garmin's advanced SubWave™ sonar network, surface personnel can track critical dive information and respond quickly if attention is required.
Monitor key dive data including:
- Tank Pressure Levels
- Diver Depth
- Diver Distance from Buoy
- Dive Status Information
- Network Connectivity
Automatic alerts can notify support crews if a diver exceeds predefined depth limits or experiences tank-related concerns, helping improve safety throughout the dive.
Two-Way Underwater Communication
The Descent S1 enables communication between surface teams and divers using preset messages transmitted through the Garmin Dive™ smartphone app.
Features include:
- Surface-to-Diver Messaging
- Diver Message Reception
- Extended Diver-to-Diver Messaging Range
- Preset Safety & Communication Messages
- SubWave™ Sonar-Based Communication
This advanced communication system helps divers stay informed about changing conditions or important updates while underwater.
SubWave™ Sonar Network Technology
Built around Garmin's powerful SubWave™ sonar networking platform, the Descent S1 can support up to eight divers simultaneously when paired with compatible Garmin equipment.
The network allows:
- Multi-Diver Monitoring
- Real-Time Position Awareness
- Tank Pressure Tracking
- Depth Monitoring
- Diver Messaging
- Return-to-Base Navigation
The system creates an interconnected underwater communication environment that enhances both safety and dive coordination.
Diver Location Tracking
Surface operators can track the approximate range of divers connected to the SubWave™ network at distances of up to 100 metres from the buoy.
Benefits include:
- Improved Diver Awareness
- Group Dive Management
- Easier Diver Tracking
- Enhanced Safety Monitoring
- Increased Operational Control
This feature is particularly valuable for dive instructors, boat crews, expedition teams and professional dive operations.
Find My Buoy Navigation
Networked divers can view the distance and direction back to the Descent S1 Buoy directly from their compatible Garmin Descent™ dive computer.
This innovative feature provides:
- Clear Return-to-Base Guidance
- Improved Orientation Underwater
- Enhanced Situational Awareness
- Easier Navigation in Reduced Visibility
- Greater Diver Confidence
By maintaining awareness of the buoy's location, divers can navigate more efficiently and safely during their dive.
Post-Dive Heatmap Analysis
Following the dive, divers can review underwater exploration heatmaps through the Garmin Dive™ smartphone app.
Post-dive review features include:
- Underwater Route Visualisation
- Exploration Heatmaps
- Dive History Analysis
- Dive Log Synchronisation
- Team Dive Review
These valuable insights help divers better understand their movements and dive patterns after returning to the surface.
