  • Patent number: 4569525
    Abstract: The Golfer's Teaching Aid is a simulated golf club which teaches and provides the user with instant visual indication of proper and improper positions of the club throughout the swing, from address, backswing, downswing and follow-through. An error in any club position is easily visually ascertained and corrected. The Aid utilizes a square shaft and a pyramidal shaped indicator above the club's grip and which are in axial alignment with each other such that the sides of each are in complimentary alignment with each other. The sides are orientated such that when the user is addressing a golf ball, the user sees only one side of the shaft and one side of the indicator if and only if the Aid is in the correct position and attitude. Additionally, the indicator will point toward the user's middle torso if the Aid is again in the correct position. Any deviation from the above is an instant visual indication to the user of a flaw in the stance, grip and/or arm position.
