Someone had to be the maker of the world's loudest whistle...and we found him!
Great for animal training, sports events, survival gear, scuba divers (yes, it even works underwater), police, fire, etc..
Being heard can, on rare occasion, be a matter of life or death. Buy one and keep it handy...just in case. The first thing that goes into our pockets when we head out for a trek on the frozen lake.
