How does the Plane Fin work?

The Plane Fin is located at the top of the Explanar hoop, and is an important reference point to see whether you are swinging on your optimum swing plane. When you perform your golf swing you move through different planes, and if you are in line with your optimum swing plane at the top of the back swing, you will hit a much more accurate shot. The Plane Fin helps you find your optimum swing plane as it will alert you if you are over rotating your forearms, as the Power Roller will go over the top of the Plane Fin or too much on the inside of it. The Plane Fin therefore allows you to perfect the complete movement of your swing, enabling you to play much more accurate shots on the golf course.
