Abstract: A golf club putter head includes a faceplate groove pattern configured to provide the putter head with an elevated center of gravity. In one preferred form, a club head body defines a faceplate having at least one and preferably multiple elongated grooves formed therein to extend generally in a heel-to-toe direction, with at least one groove positioned above a vertical mid-point of the club head body. The groove depths progressively increase in a top-to-bottom direction so that the putter head center of gravity is elevated to a position spaced above the vertical mid-point of the club head body. When striking a golf ball, the elevated center of gravity functions to minimize initial ball skidding and to promote early smooth ball roll toward a target such as a cup on a golf green.

Abstract: A system is described for monitoring the swing path of a golf club head and for monitoring flight characteristics of a golf ball following impact. A processor utilizes data from spaced apart spaced sensor arrays in determining the club head speed and head angle of a golf club during the swing phase of the club. Image capture devices captures successive images of the ball after impact, and the system processor generates data reflecting ball flight characteristics based on a comparison of the images.
