The Storm whistle is approximately 3 inches x .875 inches and .6 ounces.
The Storm whistle is the loudest whistles in the world, capable of being heard over a half mile away and even able to work underwater. Easy to hold, easy to use and easy to hear. The Storm whistle is used by Police, military, search and rescue teams and industrial safety personnel as an alarm and personal. The Storm whistle works by utilizing a resonance chamber attached to the whistle that enables the whistle to focus its sound like a laser beam and blast a noise twice as loud as any whistle made in the world. This same harmonic chamber also acts to protect the whistle from mud, snow, sand … even water. Proudly made in the USA.

We're using this whistle as part of our Neighborhood Watch safety plan. We wear them when we go walking our dogs around the neighborhood. Many homes in our ten-square block NW have whistles and a protocol for their use. When any of us is in trouble, we blow and those who hear it close by come out on their porches to blow theirs. Last week, there was a home break-in happening when the mom & her two kids came home. She and the kids ran to our home next door where she called the police and we began to blow our whistles. Within a few minutes, people from as far as two block away had arrived at the site to witness with their presence until police arrived. A great whistle for a great neighborhood.
