The Swing Mason System consists of a laser pointer and sensor that works indoors and outdoors. The laser pointer is mounted on the shaft of a golf club and can be adjusted 360 degrees around its axis and 360 degrees around the golf club shaft. It has a safety feature (accelerometer) that allows the laser to work in a safety zone only. The sensor position is parallel to the target line within a club grip length apart from the ball. The sensor has wide forgiving and narrow precise field settings to adjust to the golfer’s desired level of accuracy.
