Simrad SC90 System diagram

The Simrad SC90 sonar system comprises a processor unit (computer), a transceiver unit, a power supply and the hull unit with the Motor Control Unit and the transducer.

A colour display is also required. This display is normally not a part of the sonar delivery.

The cable between the wheelhouse units and the transceiver in sonar room must be a high quality Ethernet cable. It can be purchased locally, or ordered from Simrad.
