The Storm® All-Weather Safety Whistle is the loudest whistle on the market. Its patented design allows it to be heard up to fifty feet underwater, due to its unique sounding chamber forcing out all water when the whistle is blown.
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.
The Storm and Windstorm whistles are the loudest whistles in the world. If having a personal safety whistle that can be heard through glass, over the noise of crowds and over the drone of machines, these are the whistle for you.
