I am having problems with my Navman 4430 fish / depth finder. I believe it is the transducer. The display monitor works but I am getting an inaccurate reading for the depth. It always reads 15 feet. Any Suggestions?? I was wondering if I could purchase a new transducer. If so I need help finding one in the US.
Will the Navman Fish 4431 Transducer work on the Fish 4430?
