Windstorm™ Whistle

• The Windstorm Whistle Outdoor Powerful Survival Whistle is a refined version of the world's loudest Storm Whistle. It inherits powerful waterproof capabilities and a patented sound-producing structure. While more compact, it still produces an extremely penetrating, high-decibel sound.
• Patented Harmonic Chamber Technology: Unlike ordinary whistles that produce diffuse high and low-frequency noise, the Windstorm recycles energy and concentrates it into a single frequency of 3150 Hertz (Hz). This frequency is the "golden tone" most easily recognized by the human ear amidst ambient noise, and its amplitude is twice that of standard whistles.
• All-Weather Waterproof and Underwater Sound Production: The unique sound chamber design ensures that whenever it's blown underwater, air pressure forces out all water from the mouthpiece. This technology allows it to be used underwater, with a sound transmission range of up to 50 feet (approximately 15 meters), making it trusted by divers and lifeguards.
• Extreme Penetration: With a maximum output of 120 decibels, the sound produced is 75% louder than most commercially available whistles. Its high-frequency and clear sound quality can easily cut through wind, waves, and complex human-made noise.
• Lightweight and Portable Design: Optimized for outdoor sports, athletic events, and daily self-defense, its compact size saves space and can be easily integrated into your EDC (everyday carry) system.
• Made in USA Quality: Entirely produced in the United States, ensuring material durability and the precision of the sound-producing structure, meeting the stringent requirements of professional coaches and outdoor enthusiasts.
• WARNING: This whistle is extremely loud, and prolonged use may cause hearing damage. Please use hearing protection and never blow this whistle near anyone's ears. Keep out of reach of children.
