The device is used in a method of custom-fitting golf clubs in which the proper swing weight, length, and lie and loft angles of a golf club are determined. The method of fitting consists in a series of steps in which a golfer hits a series of balls through the photobeams with a club which is incrementally lengthened, weighted, and has its lie angle adjusted. The adjustments are made until the point is reached at which the golfer imparts maximum velocity.Other References
