ALL WEATHER SAFETY STORM WHISTLE

The Storm® All-Weather Safety Whistle is the loudest whistle on the market. It was carefully designed to produce the most powerful sound waves possible, and can be heard through walls, through glass and through water. This Storm whistle also allows you to be heard up to fifty feet underwater, due to its unique patended sounding chamber forcing out all water when the whistle is blown. Creates a clear, high frequency sound, with a power rating over 75% greater than other referee and safety whistles. Performs in all conditions, in any weather or safety situation: blown and heard on land, up to 1/2 mile. A high-impact, non-corroding thermoplastic protective housing is easy to grasp. Because of the patented harmonic chamber that is unique to the Storm whistle, it allows to be blown when held right side up or upside down, forcing all water to be purged when the whistle is blown that the high and low frequency sounds are recycled and focused into extremely loud single 3150 hertz frequency of
