Re: Raymarine compatible transducers?
From what we've found, temp sensors are usually in the speed sensor.. FWIW we have just bought a new but discontinued RM ST40 depth meter that is working fine on an '80s vintage Signet transducer. All we had to do was figure out the wiring connections.
Another option today is the Airmar DST800 transducer.. it's a powered transducer that measures speed, temp AND depth in a single package.. and transmits that data on NMEA 0183 or 2000 depending on model. Kind of a neat idea, but would require pulling a power feed to the transducer and the comm cable back.
Most transducers today can handle a certain amount of deadrise.. and there's always the 'in hull' method of installation too...
