This is not your ordinary whistle for defense. The single flute architecture offers a particular frequency designed to increase over-distance sound levels, cut background noise generated by weather, rushing water, air and ground traffic, and other distracting noises. Over the widest range of adverse circumstances, the primary central frequency produces the most piercing tone. It is made of a solid titanium alloy block, so there are no moving components and nothing to lose or replace. It is easy to blow the thin, streamlined air pipe and will create a much louder sound with less effort.

In cold, wet or snowy weather, the titanium alloy helps you to use it. The whistle body is robust and will last you a lifetime against fire, cold and crushing power. onstructed from polished TC4 titanium alloy for durability
