The ultimate survival whistle. The whistle emits a high-pitched sound that is significantly louder than a conventional ball whistle. The whistle is useful at sea, on a mountain (hiking), or anywhere as a personal protection accessory. This multipurpose whistle also has a waterproof compartment to store a survival note. A compass is also built-in to help you navigate your way around a site. All these features are built into this nifty whistle: thermometer, compass, storage warehouse, mirror, LED light and a magnifying glass. Don't go on a trek without one!
