Abstract: A putt break visualization instrument useful for improving putting includes an elongated object such as a crossbar that extends from the shaft of a putter and is normal thereto. The golfer begins by addressing the golf ball. The golfer then holds the putter above the green by the handle in the manner of a plumb line so that the shaft of the putter is vertically oriented and the crossbar is horizontally oriented. The golfer then aligns the shaft with the uphill edge of the golf ball and moves the shaft up or down along the vertical so that the crossbar extends in proximity to the cup. The golfer may use a slider on the crossbar to mark the cup. The golfer may now evaluate how well he or she has addressed the golf ball, and either repeat the process if improvement is needed or make the putt.

Abstract: The device for determining the center of gravity of an object measures the moments of the object (e.g., golf club head, or other irregularly shaped object) as it is positioned in three mutually orthogonal axes. As the weight of the object is known, the moments may be divided by the weight to determine the precise arm from the scale to the center of gravity of the object. A line is marked across the exterior surface of the object along each orthogonal axis, with the intersection of the lines defining the center of gravity of the object. A programmable electronic scale is preferably used, but other mechanical and electronic scales may be used as well. The knowledge of the precise location of the center of gravity of the object enables a technician to add or remove weight in precise amounts and locations to adjust the center of gravity precisely.
