🌊 Garmin Descent S1 Buoy (010-02546-00): SubWave Sonar Diver Messaging + Topside Diver Monitoring with the Garmin Dive App 📡🤿
Staying connected underwater has always been a challenge—especially when you’re coordinating multiple divers, monitoring air supply, and keeping a dive plan on track from the surface. The Garmin Descent S1 Buoy (010-02546-00) is built to create that connection using SubWave sonar messaging and diver monitoring—helping topside crews and divers share preset messages and improve awareness during the dive.
When paired with Descent T2 transceivers (and compatible air-integrated dive computers) plus the Garmin Dive smartphone app, the Descent S1 enables surface users to monitor critical diver info—like tank pressure, depth, distance, and approximate location—while also sending preset messages underwater. Divers can also track their distance and direction back to the buoy, and after surfacing, sync and review underwater heatmaps in the Garmin Dive app to better understand where they were diving (approximately).

Important Compatibility Note (Read This) ✅
The Descent S1 Buoy requires:
- Descent T2 transceivers, and
- A compatible dive computer (air-integrated) for diver monitoring/messaging features
Also note:
- Some compatible dive computers can receive but not send messages.
- Conditions like surface, waves, chop, objects, and diver position can obstruct the signal and reduce range.
What the Descent S1 Buoy Does: A Deeper Connection Between Surface and Divers 🤿📲
At a high level, Descent S1 is designed for two key roles:
- Topside diver monitoring via the Garmin Dive app
- Underwater preset messaging using SubWave sonar network tools (with T2 transceivers + compatible computers)
This makes it a strong fit for:
- Group dives with multiple buddies
- Charter operations and dive boats
- Training scenarios where supervision matters
- Anyone who wants better situational awareness while divers are underwater
Monitor Up to 8 Divers: Tank Pressure, Depth, Distance + Awareness 📡👥
For increased awareness, the buoy can be paired with up to eight Descent T2 transceivers (included in the Descent S1 + T2 bundle version, if you choose that bundle). With the Garmin Dive app, surface users can monitor:
- Diver tank pressure
- Diver depth
- Diver distance from the buoy
- Approximate diver locations on a map within the SubWave sonar network (conditions can reduce range)
This turns the Descent S1 into a central reference point for monitoring the team.
Preset Sonar Messaging: Communicate What Matters, When It Matters 🗣️✅
Topside crews can use the Garmin Dive smartphone app to exchange preset messages with up to eight divers (with T2 + compatible dive computers). That means surface users can:
- Send alerts when something needs attention
- Improve coordination without guessing what’s happening below
Again, message send/receive behavior depends on the compatible dive computer model (some can receive only).
Diver Navigation Aid: Track Distance and Direction Back to the Buoy 🧭
For positional awareness underwater, divers can see:
- Their distance from the Descent S1 buoy
- Their direction back to it
This helps add a simple, practical reference point—especially useful when managing navigation and returning to a known location.
Post‑Dive Heatmaps: Review Underwater Activity After Surfacing 🗺️
After the dive, divers can sync and review underwater heatmaps in the Garmin Dive app to see approximately where they were diving. It’s a helpful way to:
- Visualize where the team spent time
- Compare planned vs. actual movement
- Build better understanding of dive sites over time
(As noted, it’s approximate and conditions can affect results.)
Built for a Full Day on the Water: 15-Hour Battery Life 🔋
The Descent S1 buoy is designed to be deployed for long sessions:
- Up to 15 hours of battery life for a full day of diving before recharging
