  • Patent number: 7195565
    Abstract: An improved golf club fitting system for fitting a set of golf clubs to a player includes the steps of measuring a player's hand grip strength and selecting a representative golf club having a dead weight directly proportional to the player's grip strength. The club length and the swing weight of the representative golf club are then determined by standard testing procedures commonly used in the golf club industry. A balance index (BI) for the representative golf club is then computed by dividing the dead weight (DW) by the swing weight (SW) (DW/SW=BI) and the balance index (BI) is compared to the dead weight to determine generally corresponding values for the remaining other golf clubs in the set such that the system user can match different irons and woods to the representative golf club thereby creating an ideal matched set of golf clubs for the player.
