I've been fishing for many years. I have a pontoon with a trolling motor and various fishing tackle for bass, striper and sunfish. I do not plan to do any tournament fishing. I just like to go out and fish or take my kids and grandkids out. I am looking for a good fish finder for less than 300. I don't know anything about fish finders. Right now, I just fish by instinct and have landed some nice bass. Thank you so much for all your help
