Storm Safety Whistle
The Storm All-Weather Safety Whistle is the loudest whistle on the market. With a unique patented design that allows it to be heard under water, up to 50 feet, the sounding chamber forces all water to be purged when the whistle is blown. Perfect audible signaling device for scuba divers, lifeguards, and other outdoor activities. Creates a clear, high frequency sound, with a power rating over 75% greater than other referee and safety whistles.
