This Wind Storm World's Loudest Safety Whistle is black.
When being heard is a matter of life or death, the World's Loudest Whistle from Wind Storm will not let you down. It features an harmonic design with a dual chamber that quickly purges for uninterrupted sound. It generates a tone 100% louder than a standard police or safety whistle. Constructed of high-impacted thermoplastic, the safety whistle can be heard above crowds, howling wind, over virtually any competing sound and will perform in any wet or dry environment. It will work underwater!
Sound will discharge above, on or below water. Great for scuba divers, campers, boaters, hikers, hunters, game officials, personal protection, and more!
