Dive messaging and navigation requires line of sight between two compatible receivers with the latest compatible software versions. Obstructions and other environmental factors may affect receiver connectivity and may delay or prevent the sending and receiving of messages. With good connectivity, data can be successfully sent between divers in under 20 seconds. If connectivity is poor, devices will attempt to send data for up to two minutes. This is a supplemental feature that should not be relied upon as a method to receive emergency assistance and should not replace traditional dive safety tools and procedures.

To send messages and/or to track the location of compatible devices, this device must be connected to a compatible mobile device using the device's Wi‑Fi^® connection and the Garmin Dive™ app. The connectivity range of the device's Wi‑Fi connection will vary depending on the make and model of the mobile device used. This product should not be relied upon as a method to receive emergency assistance and should not replace traditional dive safety tools and procedures.

Surface conditions can affect device function and connectivity. Certain objects, including, but not limited to, vessel hulls, swim platforms, reefs, or kelp, can block the device's signal and cause gaps or delays in data transmission.

You should not rely solely on the buoy for underwater navigation. The navigate to buoy feature requires line of sight with the buoy. Location and distance information from the buoy is not precise, and should be used as a supplement, and not a replacement, for diver training in navigation, search, and positioning.

This device is not a personal floatation device and cannot support the weight of a person or any diving gear. Use of this device in such a manner could result in possible personal injury and/or property loss or damage.

The device range and availability of messaging and/or location tracking depends on the type of compatible devices to which this device is communicating (Dive Product and Feature Compatibility).
