The Greens Professor Putting Training Aid

If you've had enough of three-putts destroying your round, don't call it quits, call in the Greens Professor! The advanced laser technology automatically measures the face angle of the putter to help you learn how to consistently square the clubface when setting up your putt and strike the ball with the clubface square to the putting line. From the very first session, you'll fine tune your muscle memory and start enjoying the perfect putting stroke you've always dreamed about. Works with any putter indoors and out. Comes with instructional DVD by former tour pro Jerry Foltz and mirror for putter. Two 'AAA' batteries not included. 1-year limited warranty.
