WHAT YOU'LL LOVE

REMOTE DIVER MONITORING

Surface crew can monitor divers equipped with Descent T2 transceivers to keep track of tank pressures, air remaining, depths of the divers and more. Automatic alerts can let topside crew know if there’s an issue with tanks or depth ranges below¹.

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 about².

DIVER LOCATION TRACKING

Viewers at the surface can track the approximate range to each diver in the SubWave sonar network — with 1-meter line-of-sight accuracy, up to 60 meters away from the Descent S1 buoy¹.

FIND MY BUOY

Divers in the network can see the distances and directions back to the buoy, giving them clear return-to-base references if they drift too far from the Descent S1 buoy or become disoriented².

POST-DIVE REVIEW

After surfacing, networked divers can review their underwater heatmaps on the Garmin Dive smartphone app to see approximately where they were exploring².

RUGGED DESIGN

The sturdy, compact 2-lb buoy is impact-resistant and water-rated to 1 ATM.
