Garmin advances dive safety technology with revolutionary Descent S1 Smart Buoy
Track, monitor and communicate with those above – and below – the surface for greater situational awareness while exploring the depths
A revolutionary addition to the Garmin dive line up 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.
Advancing the diver experience
- Find my buoy: Connected divers can see the distance and direction back to the buoy – whether it’s tethered in place, on the anchor line of a boat or on the boat’s tag line during a drift dive – and use it to navigate back to the buoy.
- Diver-to-surface messaging: When using a connected Descent dive computer, divers can tell those on the surface where they are, where they’re going, if they need to come up early and their remaining decompression time.
- Extended diver-to-diver messaging: While beneath the surface, the buoy extends the range of diver-to-diver messaging capabilities. Divers with compatible Descent dive computers can exchange preset messages with one another up to 100 meters away.
- Post-dive review: After returning to the surface, view underwater heatmaps on the Garmin Dive™ smart-device app to see where explorations took place.
Revolutionizing the diving experience from the surface
Topside crews can better track divers below the surface when using both the Descent S1 Buoy and Garmin Dive app.
- Remote diver monitoring: Track tank pressures, diver location and depth, and more when divers are equipped with a compatible dive computer and Descent T2 transceiver. Automatic alerts can also let topside crew members know when a diver’s tank pressure is low.
- Surface-to-diver messaging: Topside crews can exchange preset messages with connected Descent dive computers underwater, allowing them to communicate with divers and send out a diver recall if the dive needs to be cut short.
- Diver location tracking: Track the approximate range to each diver in the SubWave sonar network—up to 100 meters away from the buoy2.
Rugged and connected
The compact Descent S1 Buoy weighs just 2 pounds and has an IPX8 water rating to 10 meters. The rechargeable lithium battery provides up to 15 hours of battery life so it can be used during a typical weekend dive trip before needing to be recharged. To keep divers connected to their topside crew, the buoy uses Wi-Fi® technology to wirelessly connect to the Garmin Dive app, up to 60 meters away.
SONAR COMMUNICATION: YOUR DEEPER CONNECTION
This revolutionary diver communication buoy works with the Garmin dive ecosystem, enabling topside crew members to monitor and track their dive groups — as well as exchange preset messages with divers wearing a compatible dive computer paired with a Descent™ T2 transceiver. Networked divers can also see their distance and direction to the buoy for return-to-base reference.
SUBWAVE™ SONAR NETWORK CAN SUPPORT UP TO EIGHT DIVERS
EXCHANGE PRESET MESSAGES VIA THE GARMIN DIVE™ SMARTPHONE APP
MONITOR TANK PRESSURES, DEPTHS, DIVER DISTANCES AND MORE
NETWORKED DIVERS CAN VIEW THEIR DISTANCE AND DIRECTION TO THE BUOY
ONCE THEY’VE SURFACED, DIVERS CAN REVIEW HEATMAPS OF WHERE THEY EXPLORED
POWER A FULL DAY OF DIVING WITH UP TO 15 HOURS OF BATTERY LIFE
REMOTE DIVER MONITORING
Surface crew can monitor divers equipped with compatible dive computers paired with Descent T2 transceivers to keep track of tank pressures, depths of the divers and more. Automatic alerts can let topside crew know if there’s an issue with tanks or depth ranges below.

TWO-WAY MESSAGING
Via the Garmin Dive smart-device app, topside crew can exchange preset messages with the networked Descent™ dive computers below, alerting divers if there’s a situation they need to know about. The Descent S1 buoy also extends the range of diver-to-diver messaging.

DIVER LOCATION TRACKING
Viewers at the surface can track the approximate range to each diver in the SubWave sonar network, up to 100 metres away from the Descent S1 Buoy2.
