The Fox 40 Pealess Whistle
Whistle technology – from primitive to powerful
Why don\’t \”pea\” whistles measure up to Fox 40? It\’s because they use centuries-old technology a pea or a ball, vibrating against a drum-like cavity to produce sound.
Less powerful sound isn\’t the only drawback. Things can stick to the pea moisture, saliva, dirt, water even ice, in winter.
It doesn\’t take much to set the stage for failure one good blow on the whistle and the pea can jam in the whistle cavity.
Even a brand new pea whistle can go totally mute if you blow too hard, as you might in a panic situation. A jam-up means no vibration, no sound, no communication.
The ingeniously-designed Fox 40 whistle doesn\’t use a pea to generate sound. In fact, there are no moving parts whatsoever nothing to obstruct sound, nothing to stick, freeze or fail.
Fox 40\’s patented design moves the air blast through-tuned chambers.
