Might not be the most appropriate place to be asking but does anyone out there that fishes from a boat use fish finders to judge where fish maybe holed up at..? I'm planning to fish more on small to large rivers and small lakes. I'm looking at getting a Sea Eagle 285 Pro FPL in a few weeks and see that there is provision for mounting a fish finder on it. Does anyone have any recommendations on what type, make of fish finder might be the best to get or is it maybe just a waste of time thinking about it..? I'm thinking something that would offer side scanning might be good..
