‘Storm’ whistleThe world’s loudest whistle will certainly attract attention when you need it. All weather design, it even works underwater! Used by the US Navy Seals, Coast Guard and Police forces. Black with black lanyard. With a standard whistle, nonproductive high frequency (over 5000 hertz) and nonproductive low frequency (below 2000 hertz) sounds are created. Because of the patented harmonic chamber that is unique to the Storm whistle, these high and low frequency sounds are recycled and focused into an extremely loud single 3150 hertz frequency of double the standard amplitude. All prices included postage and packing to UK(£) and Euro zone(€); for USA and rest of the world prices please contact us. info@saltyjohn.co.uk.
