fish symbols- no fish arches
I have a hds 7 gen 2. I know it is best to use fish arches. I have set sensitivity to on, off,turned sensitivity up and down and still have not seen any fish arches. I have not seen a thing on the screen, not even a dot or dash. Am I doing something wrong. Could my transducer be bad? I have a transducer on the front and back with a switch to change transducers. This is the right transducer, the same as the one used on my x510c. Since I have been facing this problem I have had to use the fish icons exclusively.I feel this has got to be some kind of setting since I get absolutely nothing on the screen. Anyone have any ideas? I am tired of looking at cartoon fish.
