The Storm and Windstorm whistles we manufacture are the loudest whistle in the world, capable of being heard over a half mile away. Utilizing a patented resonance chamber integrated into the whistle, the sound is focused like a laser beam and blasts an alarm twice as loud as any whistle made in the world. This same harmonic chamber also acts to protect the whistle from mud, snow and sand allowing the whistles to even work underwater.
The more compact version of the Storm whistle, The Windstorm™ whistle has a slightly lower decibel rating than the Storm, but has the same waterproof capabilities, tremendous power, and sleek design.
Tests show that the Windstorm™ whistle produces a sound which is more easily heard when compared to other popular whistles. Tested by an independent research team under the most demanding scientific methods, the Windstorm™ competed head-to-head for loudness against the most popular whistles in the world.
