Abstract: A system and method by which antenna type loops are situated at predetermined positions about a race track in which a plurality of contestants are passed sequentially over the loops while carrying a transmitter arranged to transmit a low radio frequency signal of a frequency discreet for each contestant and in which a series of timers controlled by a single clock are arranged in reference to each contestant so that at the start of the race all of the timers are made to start to operate in timed unison and whereby the several timers associated with each contestant are sequentially stopped upon the signal from the transmitter emanating from each contestant being sequentially received at the succession of loop antennas to indicate the lapsed time from the start of the race to each station incorporating an active loop.
