The Fox 40 Whistle is the gold standard for rescue professionals worldwide.
The Fox 40 Whistle is loud enough to be heard above ambient noise, the roar of engines, breaking waves and thundering gale-force winds. The chambers are designed to self-clear when submerged in water. It has a patented three-chamber design and no moving parts to freeze, jam or deteriorate. The harder you blow, the louder the sound. This whistle provides reliable, flawless and penetrating sound.
Be heard. Be safe.
