Abstract: A sports timing device for referees, officials, umpires, coaches and the like. The timer is ideally adapted for football or basketball officiating and it contains circuit means for generating necessary timing signals for officiating the game. The circuit is initiated manually by depression of a primary switch, and timing alarm signals generated by the circuit actuate tactile stimulation means to vibrate the device enclosure to warn the referee or official without the necessity of him visually observing the apparatus. In the football mode the device preferably provides an alarm after expiration of twenty five seconds. In the basketball mode the device provides three second, five second and ten second warnings. Low battery signalling means are incorporated in the circuitry for immediately warning the user that the battery is weak prior to commencing a timing operation; also, an LED provides an immediate dead battery warning.
