ABSTRACT:
A sporting apparatus for use in football. The sporting apparatus is a system that measures the manner in which football downs and distance is calculated in football. The system includes two down markers, a ball marker, and a hand held device which are in visual contact with each other through a series of radio wave or light wave communications. The system eliminates the need for the traditional down markers used in today's football games in which distance must be frequently checked manually.
