ABSTRACT:
A device for insuring that the striking surface of a sports implement is properly oriented prior to the initiation and completion of a contact swing. Two position orientation sensors are affixed to the shaft of the sports implement. One sensor senses the roll position of the striking surface, and the second sensor senses the pitch position of the striking surface. When both of these sensors indicate that the striking surface is properly oriented, an audible signal is generated. This signal is maintained for as long as the striking surface is properly oriented.
