This Garmin Descent S1 Buoy is a 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.
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 meters away from the Descent S1 buoy.
Find My Buoy
Divers in the network can see the distances and directions back to the Descent S1 buoy, giving them clear return-to-base reference and increased situational awareness.
Post-Dive Review
After surfacing, networked divers can review their underwater heatmaps on the Garmin Dive smartphone app to see approximately where they were exploring.
Rugged Design
The sturdy, compact 2-lb buoy is impact-resistant and water-rated IPX8 to 10 meters.
Long Battery Life
The rechargeable lithium battery gives up to 15 hours of battery life, letting you dive longer between recharges.
Secure Connectivity
Wi-Fi technology wirelessly connects the buoy to the Garmin Dive smart-device app within a range of up to 60 meters.
Multi-GNSS Support
On the surface, multiple satellite systems (GPS and GLONASS) aid signal reception in challenging environments.
