With an Plane adjustable to four different positions (90*, 84*, 78*, or 70*), you really can create the perfect path and arc for your game. As the angle changes, the arc does too. Set either one or two Alignment Sticks above the ball and and create an overhead alignment tool to check your body alignment, as well as start line on the ball using the Gate in front. Using an Alignment Stick, set up and easy 'rail drill', running the shaft of the putter along the Stick for a perfect, repeatable stroke.
