The Storm All-weather Safety Whistle is the loudest whistle in the world. Period. Its unique patented design allows it to be heard under water, up to 50 feet, because the sounding chamber forces all water to be purged when the whistle is blown.
The Storm Whistle creates a clear, high frequency sound, with a power rating over 75% greater than other referee and safety whistles. The Storm Whistle is relied upon by the U.S. Armed Forces, various U.S. government agencies, numerous police departments, NFL referees, the Red Cross and numerous other organisations.
This whistle performs in all conditions, in any weather or safety situation: blown and heard on land, up to 1/2 mile, and even underwater, up to 50 feet.
non-corroding thermoplastic protective housing is easy to grasp and the patented double chamber design allows it to be blown when held right side up or upside down, forcing all water to be purged when the whistle is blown.
