It acts as if the transducer is out of the water with random crazy depth readings. I have tried turning on and off resetting to default, removing power, and a different transducer. I can not hear a click on neither transducer that I tried. It worked fine yesterday. Temp, time and GPS worked fine....I also had no display of the bottom. My guess is that the unit has quit sending the sonar pins to the transducer.
Any suggestions short of a new unit or sending in for repair?
