Sending Diver Messages
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.
When paired to your compatible Descent™ transceiver, you can send preset messages to other members of your dive network up to 30 m (98 ft.) away.
