发明名称 Golf club sighting and alignment system
摘要 <p>The present invention provides for a "rifle sighting system" on the top surface of the clubhead which allows the goifer at the address position to align the ball where the center marker on the clubface will be at impact. This system factors in the effect the downward bowing of the shaft on the forward swing has on the center of the clubface's position at impact. It also factors in the parallax visual error the golfer experiences as he tries to align the center of the clubface to the ball. <IMAGE></p>
