Did you know that the first major sports event to be refereed with a whistle was a soccer match, held in 1878 at Nottingham Forest. Before that they waved hankerchiefs to signal. Acme have been supplying quality whistles from that day too. They introduced the 39Tornado39 in 1989 and claimed it to be the ultimate in power whistles with the T2000 being the best. The extra high frequency of Tornado 2000 hits heights not reached by any other whistle. This higher pith gives greater penetration and creates a crescendo of sound that cuts through even the greatest crowd noise. Ideal for everyone from the professional sportsman or teacher to the aunty needing one for the local rap concert!
