A new Golf Swing Improvement Device for helping a golfer determine the impact point of his or her golf swing. The inventive device includes a cylindrical sleeve member having a circular bore therethrough adapted to receive a shaft of a golf club, and a Plurality of spring-biased shaft contact members provided within the circular bore for contacting and hugging the shaft of the golf club, whereby the cylindrical sleeve member is free to slidably travel along the length of the shaft of the golf club during a swing thereof. The shaft contact members compensate for the taper in the shaft of the golf club and allow the cylindrical sleeve member to slidably travel concentrically along the shaft of the golf club between the handle and the head.
