hi, all
My Humminbird headunit started acting or is it transducer? the unit turns on as it is should the 2 sonar down imaging side imaging looks fine. it shows things in the water. if I turn on switch fire max mode I cant see my lure. Also sporadically the head unit will display 2 feet of water even though i'm in deeper water (20feet). the screen image on 2d and down imaging is messed up .the side imaging seems to read fine. I just updated the software for the first time to the software to 7.670. to try and fix the issue. I also have done pulled all the wires out of the head unit did a restore to factory same issue
