Abstract
An apparatus used to officiate sporting events in which the positioning of the ball on the field by the officials is critical to the play. The apparatus employs a laser beam which is directed by the official parallel to the field of play at a height below the width of the ball. In use, a first official directs the laser beam across the field to a second official who uses the laser beam illumination to properly 'spot' the ball. In the preferred embodiment, the apparatus is mounted onto the shoe of the official; in another, the apparatus is placed on an edge marker.
