Anyone good with electronics? I have the x65 and it never works. I took the unit off and hooked it up to my friends plugs and it worked fine. It turns on when hooked up with my boat, but will not find the bottom. I can switch it from the front or the helm, and neither place works. I think it might not be getting enough power possibly? Or maybe both transducers are jacked up? Basically, I turn them on, and it flashes 0 for the entire day. Water temp works, flasher at the healm works, but not the depth finder.

It has been like this for 2-3 years, I just never use it. Basically it is a 300$ thermometer.

help?
