Introducing the Garmin Descent S1 Buoy, the revolutionary smart buoy that transforms dive safety and communication for any serious underwater explorer, dive instructor, or charter operator. This is far more than a simple surface marker; it's a dedicated communication hub utilising Garmin's proprietary SubWave™ sonar networking to establish a vital, two-way link between your dive team and the surface crew.

When paired with compatible Descent™ T2 transceivers and dive computers, the Descent S1 allows topside support to track and monitor up to eight divers in real-time, displaying critical information like location (up to 100 meters away), current depth, and essential tank pressure levels, with automatic alerts for maximum peace of mind. For the submerged diver, this system provides enhanced situational awareness by showing the distance and direction back to the buoy directly on the wrist, offering a constant navigation reference to guide them safely home, while both surface and submerged parties can exchange preset messages for instant, clear communication.

Built rugged with an IPX8 water rating and featuring up to 15 hours of battery life, the compact Descent S1 is the essential piece of kit for anyone prioritising group coordination and reliable connectivity on every descent.
