I bet if you asked around, someone may have a spare unit they would give you. Hint Hint Hint ... A few years ago Brett Walker gave an older sonar to my buddy Matt. It finally craped out and Matt had to buy another one.
Well I'll take Matt's advice....If anyone has an old unit that's of no use to you, I could sure use one. My boat and everything was stolen, and I'm just trying to get enough stuff to fish. Thanks Guys....
