I fish for flatheads in the river from a boat. I always fish on the bottom but was wondering if anyone ever used a bobber to fish for flatheads in a river. The river I fish usually flows around 2 to 5 mph I would guess. I would think using a bobber you could cover a lot more area but I dont know if its possible to do or if its worth trying. Im thinking about trying it this weekend and fishing about 2 ft off the bottom. Any suggestion or comments?
