Abstract
An equipment for ball hitting practice capable of carrying out an analog or digital display of a defect in a ball hitting form to permit a practicer correct the defective form without deteriorating an appearance of a ball hitting stick such as a golf club and its balance. A small-sized gyro is arranged in a shaft of a golf club to detect rotation of the shaft about an axis thereof, to thereby generate a signal. The signal is then fed to a receiver box by wire or wireless transmission and displayed as unintentional movement of a ball hitting face of the club.
