ABSTRACT:
A gauge for accurately measuring depths of grooves formed in a face of a golf club head. The gauge includes a disk with a diameter of approximately one-half inch and a thickness of approximately one-eighth inch. The gauge also includes a ridge that extends across a flat surface on the disk. When the gauge is used, it is positioned so that the ridge is inserted in a groove in a club head face. If the ridge contacts the bottom of the groove, the disk will not lie flush against the club head face but will rock back and forth on the club head face thereby indicating that the groove conforms with the Rules of Golf as approved by The United States Golf Association.
