This is the Quick Master Sweep Protector. It's a golf training aid designed to suppress body sway during the swing, and to help you focus on lower body stability and proper weight transfer. By placing it on the ground and swinging, you can check for unconscious lateral movement, which is helpful for form confirmation during practice swings and shot practice. It has been used only a few times, and there are no noticeable scratches or damage overall. It is in good condition for normal use. *Box and instruction manual are not included. The item is only the main unit. *Please purchase only if you understand that this is a used item.
