Abstract:
A golf club head is provided with a center of gravity positioned within a partial ellipsoid defined in an impact reference frame that has its origin at the hit center of the face of the golf club head. The majority of the partial ellipsoid is located toward the golfer from the hit center and all of the partial ellipsoid is below the hit center in the impact reference frame.
