Super Loud Survival Whistle--- This whistle uses dual sound chambers so it can reach 120 decibels quickly. The sound is super loud and consistent, so people can hear you anywhere. Exceptional Water Whistle--The whistle is pealess, meaning it doesn't have any moving parts. The unique design makes our whistle float on water. Most whistles on the market don't float and don't sound normal when they're wet. So you'll feel safer with our floating whistle. Easy To Use--The lanyard and back clip's design makes it easier for you to use it. You can clip it into your pocket or wear it on your neck to free your hands. Reflective lacing keeps you visible in the dark. Made out of high-impact ABS, and you can use it for years.
