Abstract
A practice putting kit and training method for practicing the aiming a golf ball, aiming the putter, and keep returning the putter to a square position to the golf ball. The kit includes a laser golf ball that produces a planar, laser beam of light. Printed on the outer surface of the golf ball is a centrally aligned reference line aligned with the laser. The laser is connected to a control switch, an optional timer, and a battery that enables the golfer to selectively control its activation. The golfer practices aiming the reference line at the target line and then uses the laser to verify if aiming was correct. The kit also includes a stand that holds the golf ball in an elevated position behind the golfer. During use, a standard putter and golf ball is placed in front of the golfer and the stand and laser golf ball are positioned behind the golf ball and aimed at the golf ball so that the laser beam illuminates the top of the golf ball and the target line. The golfer watches the path of the golf ball and the putter head with respect to the laser line to determine if the putter was properly aimed and returned to a square position.
