Garmin Unveils the Innovative Descent S1 Smart Buoy for Enhanced Dive Safety

Garmin's New Descent S1 Smart Buoy: A Leap Forward in Diving Safety



Garmin, renowned for its cutting-edge technology solutions, has unveiled the Descent S1 Smart Buoy, a revolutionary addition to its dive lineup. Launched on July 15, 2025, this innovative buoy is designed to greatly enhance communication between divers and their surface crew, providing an added layer of safety and situational awareness in underwater environments.

Enhanced Communication and Safety Features



The Descent S1 Buoy utilizes Garmin's proprietary SubWave™ sonar networking technology, allowing surface crew members to track and communicate with up to eight divers at once. This interconnected communication system enables the exchange of preset messages between divers using compatible dive computers, facilitating efficient messages regarding their location and dive status.

Key Features:


  • - Real-time Tracking: Divers can view distance and direction back to the buoy whether it’s tethered, anchored, or being used during a drift dive. This ensures they can easily navigate back to the surface or to their vessel.
  • - Diver-to-Surface Messaging: The buoy allows divers to inform the team above about their status, such as if they need to surface early or their remaining decompression time. This feature is vital for managing safe diving practices.
  • - Extended Diver-to-Diver Messaging: Beneath the surface, divers can communicate with each other over a range of up to 100 meters, enhancing teamwork and coordination during dives.
  • - Post-Dive Review: After each dive, users can analyze their underwater explorations using heat maps available through the Garmin Dive app.

Revolutionary Monitoring Capabilities



The Descent S1 Buoy not only supports communication but also elevates the diving experience through advanced tracking capabilities. It allows topside crews to monitor divers' tank pressures and locations, sending automatic alerts if a diver’s tank pressure is low, thereby promoting safety.

  • - Track Diver Positions: The buoy can track the approximate location of each diver within the sonar network. This prevents divers from straying too far and getting lost.
  • - Surface-to-Diver Messaging: Communication doesn't stop when divers descend. The buoy enables topside teams to send messages about critical safety matters, such as recalling divers if a dive must be cut short.

Design and Durability



The buoy is compact and weighs just two pounds, with an impressive IPX8 water rating that ensures functionality at depths of up to 10 meters. It operates on a rechargeable lithium battery, providing a remarkable 15 hours of continuous use, making it ideal for weekend diving excursions. Additionally, it connects to the Garmin Dive app via Wi-Fi technology, enhancing its usability and streamlining communication.

Price and Availability



The Descent S1 Smart Buoy is now available for purchase at a suggested retail price of $2,499.99. As a critical tool for divers, dive teams, charter operations, and instructors, Garmin's latest innovation redefines safety and communication in diving.

Commitment to Adventure



Garmin's mission centers on creating products that enhance outdoor experiences. The Descent S1 Smart Buoy is a testament to Garmin’s dedication to ensuring the safety of divers while enriching their underwater adventures. As they continue to innovate, Garmin reaffirms its commitment to keeping adventurers connected, informed, and safe in their pursuits.
