Info about the GSM-DC
The Ocean Reef GSM DC underwater transceiver unit incorporates the latest innovations in underwater ultrasonic 2-way radio communication. The Ocean Reef GSM DC features a digital driver for verbal message equalization, an automatic system for activating transmission (DAT), and a double transceiver channel. The standard frequency (channel 1) is the same for all Neptune System units, so it is possible to communicate with any other GSM G.divers, Ocean Reef GSM DC, GSM G-Power, GSM G-Power SL, GSM CUBE3, M101A G.divers receive units and M105 Digital / M100 G.divers surface units. The Ocean Reef GSM DC is a dual channel (DC) unit, which means it is equipped with two transceiver channels. By pressing buttons 'A' and 'B', it is possible to change the frequency channel. Any time the channel is changed, a recorded message informs the diver of which channel has been activated (channel 1 or channel 2). The two channels allow different diving groups to operate in the same area with limited interference and confusion. The Ocean Reef GSM DC sound quality depends upon the D-Mic microphone, a special dynamic microphone with high acoustic qualities, and the microprocessor (DSP), which takes the digitized vocal message and filters out unwanted noise such as exhaust, air bubbles, and/or mask vibrations.
