when you say sonar wont work in shallow depths what exactly do you mean? are you losing bottom? is the screen just blank? what is happening. What settings are you running on the unit? What kind of transducer do you have and where is it mounted?
Could just be a transducer problem, that would be the first thing i looked at....
