Yeah I know, it's just an Eagle 480, but till I save up or win a tournament, it's what I got:D. Anyway, I get a depth reading and a dull bottom return, but it's not showing any structure or fish. Anyone else ever have this problem? Anyone know how to fix it? Please don't tell me it's another bad transducer. If I buy another, I will have bought the unit twice already with the $$$ I've spent on 'ducers.
