ABSTRACT:
A swing training device which utilizes an microprocessor controlled set of colored LEDs to teach the user to watch the ball through the contact of a ball hitting device such as a baseball bat or golf club with the ball. Also shown is a method of providing a confirmation visual for an observer to confirm the hitter has in fact watched the bat hit the ball. This swing training device may be mounted in a standard batting tee stanchion or may replace a standard batting tee stanchion. The swing training device may also be mounted in a practice golf tee especially those of the type used at driving ranges.
