Topside Communications Unit (TCU)
Marine Sonic Technology has designed the Topside Communications Unit (TCU) for ease of use.
The unit housing is sealed and made of rugged plastic. All connectors are water resistant.
Indicator lights are on the front of the unit to indicate power to the unit, communication with the
network, and communication with the towfish. Internal circuit boards seamlessly communicate with
all attached components, and an internal power supply provides the voltage for the towfish.
