Our automatic fishing reels are made of galvanized steel with a tempered spring that automatically sets the hook when the trigger is released by a fish taking the bait. Our reels are very popular for catching Crappie and Catfish. They can be attached to limbs, boat docks, the side of a boat, or any other means that will suspend the reel a couple of inches above the water. They also make an excellent device for Ice Fishing.
