  • Patent number: 5219169
    Abstract: A golf club orientation and alignment system for use when addressing and hitting a golf ball. A bubble indicator is carried at the top surface of a club head and can be adjusted to compensate for different club face offsets. The bubble indicator shows the alignment and orientation of the club head about both a line-of-aim axis and a transverse axis perpendicular to the line-of-aim axis. When the club head is aligned and oriented in this manner, a golfer can shoot more accurately, and eliminate hooks and slices. Arrangement is disclosed also for controllably adjusting the bubble indicator for varying the inclination of a hitting face of the club.
