HOW YOU WIN WITH THE QUAD TOUR: The shape turns your elbows into your body and sets your shoulders back. This relieves arm and shoulder tension, inhibits wrist action, which takes “the hands out of the putting” and promotes shoulder rotation, creating a solid putting stroke, which will give you a one-piece feel, leading to a more consistent stroke. The QUAD TOUR 17″ is the longer version of the Quad Tour Pistol Non Tapered.
