Storm High Decibel Survival Whistle

This is the loudest whistle in the world for its size and weight class, capable of being heard over half a mile away.

Using a resonance chamber integrated into the whistle, the sound is focused like a laser beam and blasts an alarm twice as loud as any whistle made in the world.  This same harmonic chamber also protects the whistle from mud, dirt, and sand, allowing it to even work underwater.  

Storm High Decibel Survival Whistle comes with compass, thermometer, firestarter, and neck lanyard.
