Whistle, Jet Scream

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.
