“The Gatekeeper” is a precision golf training aid targeting golfing enthusiasts of all levels wanting to improve their putting skills. The compact product provides accurate and honest feedback about your putting stroke, face rotation and tempo. The device effortlessly attaches to any putter shaft and unfolds to release a ball pendulum and linear visual guide.
Three ball sizes offer ranging levels of difficulty and are interchangeable through the magnetic connection at the end of the cord. The ball will only pass through the gate if your path is true.
