went out to mille lacs and my fl-20 worked flawlessly over the weekend! took it out last night to do some crappie/walleye fishing and it wouldnt work. i would put the transducer down the hole and there would only be 2 lines and they were both at the top. one at 0 and one at 20! if i turned my zoom all the way up it would read the bottom sometimes but it wouldnt read my lure or fish!!! DOES ANYONE KNOW WHAT THE PROBLEM COULD BE????
THANKS FOR ANY INFO ANYONE HAS!
