The Golfsmith Professional Putter Fitting System allows any golfer to be fit to adopt the correct putting posture by allowing the club fitter to measure important parameters correctly, such as putter length, hand and eye position over the ball and the degree of loft adjustment needed to roll the ball on the green. The putter fitting system is designed to stand alone in the putting area of a store of shop and let golfer's self diagnose, prior to asking for assistance from a fitting professional.
