Till now - only dolphins could
communicate underwater - now you can too!
Based on text messaging technology, the UDI system allows divers
to transmit pre-saved messages to other divers in the network,
at a range of up to 500 meters (550 yards). Depending on the
individual needs of the team, divers can create up to 14 text
messages that are saved in the memory of the unit.
When a message is sent, a received signal activates an audible
alert and lights up the graphic LCD screen to notify the
recipient. The recipient sends an acknowledgement back to the
A Messages can also be transmitted between individual units and
the boat unit. The result is an underwater digital network that
connects divers together to promote safety and to enable more
sophisticated communication to enhance the diving experience for
Examples of possible messages are:
"A boat is above you"
"I want to show you something"
"I need help. Slow down"
Or even -
"Will you marry me?"
