GOLF CLUB AND METHOD FOR USE TO IMPROVED GOLF GAME

摘要

Golf club includes a head having a front, ball-striking surface and a cavity arranged to removably retain therein a ball. The front surface includes an opening communicating with the cavity and arranged apart from peripheral edges of the front face such that an annular portion of the front face surrounds the opening. The head is constructed without structure in front of the opening such that when the golf club is swung against a ball, passage of the ball through the opening into the cavity is used to evaluate the swinging of the golf club. The head may include one or more channels leading from the cavity to a rear face and/or to a side face to allow flow of air from the cavity during the swing. A ball removal mechanism may be incorporated into the head to facilitate removal of the ball from the cavity.
