I generally out fish the boats around me and have for many years. I just got a fish finder a few years ago and paid $100 for it replaced it this year with one that cost $120. Shows me the depth bottom structure etc. The only reason I got one was entertianment for my two small kids and to teach them how to read conditions with a visual aid. I think they make you less of a fisherman . But that is my way of life and not for everyone.
