The JetScream Whistle focuses man made air streams through harmonically tuned chambers to create a piercing shriek audible over most other natural and man made noises.
Due to its pea-less design, JetScream 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 JetScream is just as useful in the city as it is in the woods.
