Dive messaging 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.

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).
