Abstract: A training device for improving the golf swing by providing immediate feedback of incorrect club positioning in the backswing and forward swing. The device senses the attitude of the club during the swing and comprises a small housing or case which attaches temporarily to the shaft of the golf club adjacent the club grip. Contained within the housing are one or more attitude sensing means, such as a mercury switch, connected in circuit to a power source, such as a battery, and an indicator means, such as a vibrator or an audible alarm, such that the indicator means is activated either when the golf club is correctly maintained during the swing within an acceptable swing path area defined by a limited deviation angle on either side of the ideal swing plane, or alternatively only when the golf club is incorrectly positioned out of the acceptable swing path area.

Abstract: A golf apparatus is provided for practicing aligning the head of a golf club with a golf ball to be struck by the club head prior to swinging the club. The golf apparatus has a light source on the club head for directing a beam of light toward a golf ball and a receiver on the club head for receiving light reflected by the golf ball. The light source and the receiver are positioned such that reflected light reaches the receiver when the golf club head and the golf ball are in a predefined relative position. In the predefined relative position of the club head and a golf ball, a line connecting the center of a golf ball and a point of preferred contact on the club face is perpendicular to the club face. An indicator light on the club head provides a visible indication that the club head and a golf ball are in the predefined relative position.
