This is not your ordinary safety whistle. The double flute design provides a specific frequency designed to increase sound levels over distance, cut through background noise caused by weather, rushing water, air and ground traffic, and other distracting noises. The primary central frequency provides the most piercing sound over the widest range of detrimental conditions. Made from a solid block of titanium alloy, so there's no moving parts, and nothing to lose or replace. The small, streamlined air pipe is easy to blow and will produce a much louder sound with less effort. This means you can blow this whistle for longer periods without exhaustion.

The titanium alloy lets you use this in cold, wet or icy conditions. The whistle body is durable against heat, cold and crushing force and will last you a lifetime. Absolutely essential in case of emergency, aid in survival, disaster preparedness, crime prevention, campus safety, and anything else you can think of. Don't leave home without one.
