Abstract

A lightweight, portable apparatus for measuring and custom fitting golf clubs to an individual golfer is provided. A lengthwise adjustable club shaft pivotally mounted on a base plate includes a protractor-type scale at the pivot point to set the desired lie angle and a linear scale marked on the shaft to indicate the length of the shaft. Once the desired lie angle and shaft length are determined, the address distance is measured and marked on the shaft of the custom golf club thus obtained.
