Abstract: A golf teaching device for right- and left-handed golfers to assist in assuming a consistent stance when addressing the ball for a swing. A system of mirrors connected to the base frame allows the golfer to view the position of his body in the stance and to align the framework of the device with the desired target line through a sighting apparatus on the base frame. A club facer assembly allows the golfer to position the face of the club perpendicular with the selected line of flight. Graduations on the device allow the golfer to consistently position and align his feet and the ball with the target line when addressing the ball. An extendable shaft assembly with graduations positions the club facer assembly a desired distance from the golfer in his desired stance. The extendable shaft assembly snaps into position generally perpendicular to the base frame. The position of the shaft assembly on the base frame may be reversed to accommodate right- or left-handed golfers.
