Ocean Reef Gsm Dc | Ocean Reef GSM DC, underwater wireless communication system

Description

The GSM DC™ underwater transceiver unit incorporates the latest innovations in underwater ultrasonic 2-way radio communication. The unit 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, 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 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 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.
