Raymarine forum

I upgraded to 2x Axiom 7's (RV) last year on my 210 Whaler Outrage (20 degree deadrise). The RV-100 mounted off the transom (port side) loses depth at speed but bigger issue is it kicks up a lot of spray on plane.

I know if I moved it the starboard side it would probably be more stable holding the bottom but the spray issue will remain.

Therefore I'm considering going with either the RV-220 bronze pack or RV-320 plastic pack. I have no flat areas on my hull so my understanding is I need the pair/pack. Which would you recommend?

I also see a new product - RV-420 in stainless. What can you tell me about that?

Help me decide please? I boat on Georgian Bay in Canada where max depth offshore is only up to about 300-400ft MAX.

Cheers

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.
