I am considering purchasing a Lowrance 520c from my neighbor. He is asking $350 for it with no card. It came new on his new Skeeter about a year ago & he only had it on about a dozen times. Is this a good deal for me? When I put this on my religious tracker, it will be worth more than the boat. LOL. I have no experience with a lowrance & was wondering if any of you lowrance experts would give me some input on this.

Thank you,

Jason
