发明名称 Golf club impact making device and method
摘要 A method and apparatus for registering a point of impact of a ball against a surface of a hitting implement. A multilayered impact indicator is releasably affixed to the striking surface of the implement. Each of the layers of the indicator have identical indicia on them. The top and bottom layers of the indicator cooperate in a carbonless fashion such that when the ball impacts on the top layer, the impact is communicated to and registered on at least the second layer. The indicia on the top layers is arranged to be in corresponding alignment with the same indicia on the bottom layer. The indicia includes a centrally outlined or dispositioned target area or portion. The target is surrounded by other indicia indicating the closeness of the impact to the target.
