[CA] Dragonfly 4 problem

esteban525,

Please click here to view a FAQ addressing this subject ... and particularly examine the included photo showing hull aeration caused by the lifting strakes. Your transducer appears to be installed directly aft of one your boat's strakes. You may want to try first relocating the transducer to a location on the transom which is midway between the lifting strakes. Performance may further be improved by dropping the aft end of transducer a notch or two.
