Abstract
Abstract An impact marker for golf clubs and the like. The marker is comprised of a self-contained imaging-type sheet material including minute rupturable capsules, which sheet material is applied to the face of the club by means of a pressure-sensitive non-permanent adhesive distributed uniformly over substantially all of the back side of the sheet material. The sheet material is suitably adapted to produce an image at the exact point at which the sheet is contacted by the ball during the golfer''s swing. Prior to being attached to the club, the adhesive layer is covered by an easily removed protective sheet.
