Dive messaging requires line of sight between two compatible receivers with the latest compatible software versions. Data successfully sent between divers using this feature may take up to 45 seconds to send. 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.

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).
