Abstract
Abstract A training device to improve the use of golf club irons by indicating whether the golfer tends to align his irons to hit a golf ball to the left or right of the true course. A slidable ball holder with golf club placement indicia is addressed with the golf iron. A vertical reference pole is mounted at one end of the slidable ball holder. A detachable long rigid slender pointer is attached as with a magnet to the striking face of the golf iron. The pointer indicates if the striking face of the golf iron is aligned to hit a ball to the left or right of the vertical reference pole.
