The JetScreamâ„¢ Whistle focuses manmade air streams through harmonically tuned chambers to create a piercing shriek audible over most other natural and manmade noises. Due to its pea-less design, JetScreamâ„¢ even works when wet, making it the perfect accompaniment to all outdoor activities near rivers, lakes, or oceans. Flat enough to fit in your pocket and attached to a lanyard, the JetScreamâ„¢ is just as useful in the city as it is in the woods. The JetScreamâ„¢ can be found in the survival kits of some of the most elite government forces, including the United States Air Force and the Navy Seals.
