Issues with a 596c
My 596c hd di is about 6 months old and today out on mcclure it started acting up. Dont matter what screen view I had it on it would have erratic depths. bounce from say 144 to 1.3 back to 100 then 5 foot. Never has done this before. Any ideas? I also noticed today I was shooting a rooster tail off the transducer when I was going at high speed. I was trolling for trout when it started acting up.
