The MSIII Large Putting Arc is the best training aid choice for traveling golfers, can be used indoors or outdoors and is made of durable plastic and weighing just two pounds.  The Putting Arc is strategically shaped to guide a putter along the preferred arc of a winning putting stroke, always on plane for an ensured sweet spot.  Simply place the Putting Arc on the ground and set up with the heel of your putter against the center of the arc. Features four radial sightlines that correspond to the ideal putter face position at different stages in the stroke.  Based on natural body movement that can be quickly learned, then repeated.  The correct path and correct clubface happen automatically without hand or arm manipulation and teaches your body to rotate as one unit.  The Putting Arc is a revolution that has proved successful in over 150 pro tournament wins last year.  Includes an instructional CD.
