The Windstorm All Weather Personal Survival Safety Whistle with Breakaway Lanyard out performs other whistles in loudness and can be heard up to 1.5 miles away over land and under water to a depth of up to 50 feet. The whistle is constructed using a high-impact, non-corroding thermoplastic construction that is easy to grasp. The double chamber design allows it to be blown when held right side up or upside down forcing, all water to be purged when the whistle is blown.
