    Abstract: There is disclosed an apparatus for monitoring and calculating the position and speed of a projectile as it is pitched over a target zone. A grid of infrared emitters aligned with respective infrared receivers are in continuous optical links until the ball passes an d cuts some of the links. Upon this cut, the position of the ball is stored in memory and the time of passage of the ball across the grid is recorded to later calculate the speed of the ball.
