Sending Diver Messages

CAUTION

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.

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.

  1. During a dive, press ENTER.
  2. Select Divers > All Messages.
  3. Press NEXT.

TIP: You can press PREV to scroll through your recent messages.
