How important is a fish finder?

[IndyFishing]

I would buy one if I were you. I didn't have one either until I went out a few weeks ago with a buddy down in Ky, doing some Musky fishing. I thought to ask him about the advantages of it since we were fishing in an area that was once a forest it seemed. With all the old tree trunks coming out of the water everywhere, it amazed me to see how the fish were situated around all of the trees. I thought they would be around the trees where the current broke,but they were actually between all of them where the deep pockets were.
I think you would be happy with it if you got it. I have one now []
