I always made fun of guys on the lakes with their fish finders until I had 7 straight outing without getting a nibble. I did have a few carp look at me and laugh so that was no fun either. Wanted to know if there was a particular fish finder that most use and if they are really worth it. Been looking at some hummingbirds but if it were up to my bro inlaw, I'd have the 6" all color one that sinks up with my tv and cooks me dinner. I'm looking for a basic, there is the fish stupid, put chrono's there kind of thing.
