NRS Storm Whistle

• The unique patented asymmetrical shape is designed to augment and amplify sound like no other whistle.
• The Storm even works underwater; its sound can be heard up to 50 feet away!
• The Storm’s focused 3150 Hertz frequency is the most readily heard tone above other noises in the environment.
• A whistle is vital for signalling above the sound of surf and whitewater.
• Remember, in most on-the-water situations a sounding device like a whistle is required by the Coast Guard.
• We recommend against attaching the whistle to the zipper pull on your life jacket. That can result in accidental unzipping.
