STORM All-Weather Safety Whistle with Bag & Lanyard, Orange
The Storm whistle is twice as loud as any other mouth-blown whistle in the world. 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.
