I wouldn't wait any longer than I had to. It sure puts a lot of fun back into fishing. Yesterday I pulled up on a tree that has been really good for crappie. Saw nothing. Got nothing. Spun the Panoptix around and there they were out in the middle of the lake just meandering around. Hit the trolling motor. Moved over to within 40 ft of them and cast to them. Sure made for a good fishing trip.
