Abstract
Speed and precision of aim are both recorded automatically. A target, which may be a light capable of being moved horizontally and vertically, is placed in a surface plane which forms the goal area. The ball, covered with a metalised paint, is hit towards the goal and its speed measured by a radar detector as it passes through the surface. Precision of aim is recorded using an instant print camera or a video tape recorder, with a correction factor applied to allow for the ball's trajectory and distance from the goal area. The speed may also be measured by determining the time elapsed during the passage of the ball.
