The JetScream Whistle is a low profile, pea-less whistle for survival, safety, and communication purposes. This exceptional whistle focuses manmade air streams through harmonically tuned chambers to produce a piercing shriek audible over most other natural and manmade noises. Because the whistle is pea-less, JetScream even works when wet, so it is the perfect accompaniment to all outdoor activities near rivers, lakes, or oceans. Slim enough to fit in your pocket and attached to a lanyard, the JetScream is just as practical in the city as it is in the woods. The JetScream is included in the survival kits of some of the most elite government forces, including the United States Air Force and the Navy Seals. Length: 2.3". Wt: 0.3 oz.
