Characteristics of M105 DIGITAL

The M105 Digital is a surface to diver communication unit which allows surface personnel to talk with divers in the water and vice versa. The unit uses a 6V DC lead battery, allowing up to 48 hours of operation, or may be hardwired to a 12V DC source. The system is activated only when the transducer is connected, preventing unwanted loss of battery power. To start communication, the transducer must be lowered into the water; the standard cable length for the transducer is 10m (33 ft). Transmission is activated by pressing the microphone button, which will emit a short beep letting divers know transmission is about to begin. It will return to receive mode when the button is released.
