Storm is made from high impact thermoplastic and can be heard above crowds, howling wind or virtually any other competing sound to draw immediate attention. These whistles will perform in any wet or dry environment. Sound will discharge on or below water. The Storm is ideal for Backpackers, Surfers, Paddleboarders, Sailors, Emergency Workers and can also be used as a personal attack alarm. There is no worry about signal, batteries or other technical failure - if you fall off your mountain trail bike and end up injured in a ravine, this whistle will get you found. Technical Information: The Storm All-Weather Safety Whistle is the loudest whistle on the market. It's 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. Made in the USA. It's perfect for divers, lifeguards, and for recreation! Creates a clear, high frequency sound, with a power rating over 75% greater than other referee and safety whistles. Test Results The Storm whistle is twice as loud as any other mouth-blown whistle in the world. Initial testing was conducted by the Hearing Conservation Programs Inc., who tested the decibel rating of various military, sports and survival whistles against the Storm whistle. These first tests were performed in a sound proof booth at a distance of 15 feet with the whistle being blown by mouth, and had a number of variables, such as the person blowing the whistle and the accuracy of the sound level devices. The second set of tests, conducted by the Central Institute for the Deaf, were performed in open air at a distance of 15 feet, 25 feet and 50 feet. Here the whistles were attached to a constant air source which was adjusted to the normal blowing strength typically generated by the mouth. The sound the whistles made was then analyzed by computer, using a double blind technique, detailing the amplitude and signature of the sound created. With a standard whistle, non-productive high frequency (over 5000 hertz) and non-productive 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 our extremely loud single 3150 hertz frequency of double the standard amplitude. The focused 3150 hertz frequency was generated intentionally in accordance with government recommendations that showed that the 3150 hertz tone is the most readily heard over the noise of motors, crowds, and explosions. In all these cases, test results showed the Storm whistle as being twice as loud as the other whistles. Presently, the Storm whistle is being used by these groups as a personal alarm where an extremely loud alarm is necessary: Special Forces Fort Bragg, North Carolina U.S. Dept. of Agriculture U.S. Dept. of the Interior U.S. Coast Guard, Washington, D.C.

The All-Weather Safety Whistles comes in two styles: the Storm and the Windstorm. The Storm is the original All-Weather Safety whistle, and has been carefully designed to produce the most powerful sound waves possible, and can be heard through walls, through glass and through water. The Storm whistle is the loudest whistle in the world, and can be heard over a quarter of a mile through trees and over a half mile over water. Over the years, however, a number of our customers desired a whistle that was a little more compact. They wanted a whistle small enough to fit into a hand bag, on keys, oron a life preserver, but loud enough to be unequivocally heard. For that reason, we developed the smaller and more compact Windstorm safety whistle. Though much smaller, the Windstorm is still the second loudest whistle in the world?only a few decibels behind the Storm. As the most powerful whistle in the world, the Storm is, easy to hold, easy to hear, and is used by safety and rescue teams around the world. The Windstorm whistle is simply the more compact and sleek version of the Storm whistle, with a slightly lower decibel rating. Both whistles have waterproof capabilities, tremendous power, and sleek design. Together, the Storm and Windstorm whistle make the greatest whistles in the world. When asked this question, Dr. Wright responds that, "as a Boy Scout leader, I use the Storm whistlewhile making sure that the scouts have a Windstorm."
