Abstract: A golf swing teaching aid device comprising a vertical free standing screen with an open space in its lower, middle area is disclosed. The device is tall enough and wide enough to block the golfer's view of the flight of the golf ball, yet the open, center space allows the ball to pass through the device in its normal trajectory. The device may include a flap for adjusting the dimensions of the open, center space or for stopping the ball within the center space rather than allowing passage. The screen may be made of an impact absorbing and impressionable material such as vinyl coated nylon, which is temporarily marked when struck by a golf ball.
