I have a old(~2002-2004) GP1850WDF unit. I'm trying to identify the transducer. It's a thru hull. It provides 50/200 freq and temperture to the unit. It is shaped like a pointed oval, 4 inches long, just over 2 inches wide. There is a cable marking, Airmar #C47 C1225, but no label on the transducer. I suspect it's a B525 model, but not sure. How can identify the model number?
Thanks
Paul
