2 Channel Diver Comms Set

2 Diver Communications set

The SAT Systems two channel diver communications set is compact, portable and robust by design and is powered by a internal sealed 12V lead acid battery.

This unit can be used for simplex communications; each diver is connected to the communication set using a single twisted screened pair cable.

The set is in listen mode until the supervisor uses the Press To Talk (PTT) switch on the front panel to communicate with one or both the divers.

Optional items in this mode are a fist microphone with PTT switch or a headset with PTT switch.

The PTT switch is not used in this mode and  the communications are permanently open. The supervisor can talk to the divers and they can talk to each other.

Separate send and receive volume controls are fitted, neither volume control can be turned totally “off”. A recording outlet allows the conversation to be recorded, as required.
