The Hammerhead is a wood (cedar) dive and rise bait that has a hard front and rubber tail that is turned onto a heavy-duty custom-made spring. Small pulls will work the bait down with a side to side action. Wider side to side action can be achieved with longer pulls. There are two screw inserts to add weight. The bait goes down to 8 feet deep without weight. Get more information at http://www.h2otackle.com
