Setting Up the Buoy with the Garmin Dive App

Before you use the buoy for the first time, you must connect to it with the Garmin Dive™ app and set up Wi‑Fi® connectivity. To ensure compatibility when you are pairing devices, you should be in a location with internet access so that your devices can download the required software updates.

  1. To turn on the buoy, hold the button for two seconds until you hear a beep.

    The buoy beeps, and the status LED flashes green while the buoy is powering on. A tone plays, and the status LED slowly flashes white.

  2. Select an option:

    • Download the Garmin Dive app using the mobile device you will use on the surface during the dive session.

    • If you already have the Garmin Dive app on your mobile device, update the app to the latest version.

  3. Scan the QR code on the bottom of the buoy with the camera on your mobile device.

    When your mobile device connects to the buoy's Wi‑Fi network, the status LED is solid cyan for three seconds. Then the status LED flashes a white double-blink while your mobile device is connected.

    NOTE: You can manually connect to the buoy's Wi‑Fi network through the system settings on your mobile device. The Wi‑Fi network name is "DescentS1-" followed by the six-digit device ID located next to the QR code. On your mobile device, select the Wi‑Fi network for your buoy, and enter "TSB" followed by the six-digit device ID.
  4. (Optional) In the Garmin Dive app, you can change the Wi‑Fi network password.
    NOTE: If necessary, you can change the Wi‑Fi password later in the Garmin Dive app. Select More > Garmin Devices, select the buoy, and select General > Manage Wi-Fi Password.
