Garmin’s New Descent S1 Buoy is a Game-Changer for Dive Safety & Communication

Garmin Malaysia just dropped a major innovation for divers introducing the Descent S1 Buoy, a compact, high-tech lifesaver designed to enhance diver communication and safety like never before.

Using Garmin’s SubWave™ sonar networking, this smart buoy connects seamlessly with Garmin dive computers, allowing surface crew to track up to eight divers underwater and even exchange preset messages mid-dive. Yep, that means real-time updates from below the surface.

“The Descent S1 buoy adds game-changing communication, navigation and safety capabilities… making it the next must-have for dive teams, charter ops, instructors and more,” said Mr. Scoppen Lin, Assistant GM of Garmin Asia.

What Can It Do?

  • Track & Locate Divers Easily
    Divers can see the distance and direction to the buoy whether it’s anchored or drifting and use it as a guide to surface safely.
  • Diver-to-Surface Messaging
    Using a compatible Garmin Descent dive computer, divers can notify the crew where they are, if they need help, or when they’re surfacing.
  • Extend Diver-to-Diver Chat Range
    The buoy also boosts underwater messaging between divers up to 100 meters away.
  • Post-Dive Heatmaps
    Sync it with the Garmin Dive app to review your underwater trail and see exactly where the action happened.

For Topside Crews, It’s a Whole New View

  • Live Tracking: Know your divers’ approximate range and depth with real-time sonar.
  • Safety Alerts: Get auto notifications if tank pressure runs low.
  • Wi-Fi Connected: Send recall messages or preset alerts to divers from the surface, no shouting needed.
  • App-Ready: Everything syncs with the Garmin Dive app, up to 60 meters away.

Built for Adventure

The Descent S1 Buoy is rugged, compact (only 2 lbs), waterproof up to 10 meters (IPX8 rating), and lasts up to 15 hours on a full charge. Whether you’re out for a weekend dive trip or leading a charter dive, it’s designed to be reliable and intuitive.

Available August 2025

  • Retail price: RM10,879
  • Available on Garmin e-store, Shopee, Lazada, AECO e-store, Garmin Brand Stores, and authorized retailers.

Whether you’re diving for adventure, training or marine research, the Descent S1 Buoy is your new essential dive buddy smart, safe and seriously cool.
