ok now that i have some attention, my depth meter will work some times or just flash -- at other times. i think it is a navco?? it has a threw haul transducer. and i found that the previous owner had painted it with vc 17. i cleaned that off and it still wont consistantly read. so, do i need a new transducer from navco or are they all the same? or is it a diffrent problem all together?
