With the Putting Plane Alignment System you can easily use the mirrored surface to check if your eyes are over the ball, shoulders are lined up, and the putter face is square. Its adjustable rails enable you to practice a perfect back and through stroke that is on plane. The angled rail allows the putter to come slightly inside as it moves back and up.
Free Putter Guide with every Putting Plane Alignment System! Keeping the putter face from rotating when using the Putting Plane System, Putting Square System, Professional Plane Rail and Learning Curve, the Putter Guide easily attaches to any mallet or blade putter.
