The DAT hands-free mode: This automatic activation system is an exciting innovation in underwater communication exclusively from Ocean Reef. The DAT system allows the option of transmitting in a hands-free mode rather than manual mode. A series of impulses are sent out, automatically keeping the unit in transmit mode for 30 seconds. After the initial 30 seconds of transmit mode, the unit will return to receive mode for 20 seconds accompanied by a series of impulses in a different tone from the first. DAT is useful when it is necessary to have both hands free while transmitting, making diving more comfortable and safer. Another benefit of the DAT system comes in the case of an emergency; by activating the DAT a series of impulses will emit every 30-20-30 seconds, which can be received at a great distance by search and rescue workers and other divers. DAT system is an Ocean Reef exclusive.
