Hey folks!
I am asking this question on behalf of my brother. He has a fishfinder' that has GPS, temp and speed. I think it's a lowrance. Recently, it is not marking bottom, but all other functions work as they are supposed to. The transducer was checked for proper location, tilt and connections, all looks right.
The unit is fairly old. Would it be a reasonable idea to simply change out the transducer? Is this the likely culprit? Ideally, he does not want to buy an entirely new unit.
Any advice appreciated!
