Based on text messaging technology wich elektromotory-vybo.cz already uses, 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 sender.
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 all.
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?"
SOS / Homing Procedure
The UDI SOS and Homing features allow direct navigation to a diver who has sent an emergency SOS message or to a boat unit that has transmitted a homing signal.
SOS: A diver in distress can send an SOS signal to other divers or to a boat unit. The receiving diver acknowledges the SOS call and receives graphical 3D instructions on his UDI unit that allow him to navigate his way to the diver in distress and provide assistance.
Remote SOS: If a diver suspects that his buddy or a nearby diver may be in distress, he or she can send a remote SOS signal to the diver. If the diver does not require assistance, he can choose to disable the signal. If he does not disable it, and is, in fact, in distress, receipt of the Remote SOS activates his unit to send an SOS.
The SOS signal is received by the other divers using the UDI system, allowing them to navigate to the diver in distress following the graphical instructions on their clear view screens.
Homing: When a diver sends a Remote Homing message to a boat unit, the boat unit transmits a homing signal that enables the diver to easily locate the boat. He then follows the graphical instructions on his screen and easily locates his target.
UDI’s advanced navigation and SOS features ensure diving safety of unprecedented levels.
A Boat unit:
An optional system to communicate with the UDI, is the UDI boat unit.
It is a compact, lightweight & easy to use.
The boat unit supports 4 different networks (each of 14 divers) and is built with high power transmitter.
The system comes in a water resistant suitcase, extra long battery power and external power connection.
The boat unit enables text message communication with the underwater divers.
It also allows divers to navigate their way back to the boat using its homing capabilities.
