The Head and Chest Reactive Target provides two targets for the price of one. The Chest strike face is right size to practice precision. The Head strike face will lay down and reset with a good shot. The reactive system and spring are made of high test steel. Both strike faces have excellent resonance and can be heard hundreds of yards away. This is a complete system including the Head, Chest, Reactive System, and Welded Base. All the shooter provides is a 2x4 of lumber.
