RE: [CA11] Transducers - bronze or plastic?
Welcome to the Raymarine Forum jharcnc,

With respect to the sonar performance of the plastic, bronze, and stainless steel RV transducers, performance should be identical. To quote a West Marine Advisor article on the subject of thru-hull transducer housing materials: "Bronze transducers are recommended for fiberglass or wood hulls. Plastic transducers are recommended for fiberglass or metal hulls. Stainless steel transducers are recommended for steel or aluminum hulls. When installing a stainless steel transducer into an aluminum or steel hull, care must be taken to isolate the transducer from the hull to prevent galvanic corrosion. Plastic transducers are not recommended for wood hulls, since the expansion of wood can damage a plastic transducer." Plastic thru-hull transducer housings are also offered for those seeking a less expensive transducer housing. For your application, it would be recommended that the RV-220 bronze pack be considered.
