ACME Onlineshop by Unterwegs

ACME's Tornado Slimline produces such a clear, penetrating tone that ensures it will be heard. The plastic whistle uses no 'pea' but is very loud!
Operationally invaluable in emergencies, rescue operations, outdoor pursuits and, naturally, sport. In use, too, at the Olympic Games. Not even 10g

Tornado 2000 is the world's loudest whistle.
Its unique design (without 'pea') produces a high frequency tone, which penetrates even very loud background noise and a low frequency pitch which can be heard at great distances.
Unsurpassed and, in the meantime, employed not only by S.O.L.A.S.
