Chuck — virtually all of the major manufacturers (including Raymarine) use Airmar transducers; chances are good that your existing transducers are also Airmar, and would interface just fine with the ITC-5. The ITC-5 can accept inputs from depth, speed, temp, wind, fluxgate compass and rudder reference transducers.
