Fox 40 Micro Whistle is designed to be small and flat with no pressure points. It can be attached to anything - life jackets, clothing, backpacks, etc. No moving parts to freeze, jam or deteriorate make this whistle flawless, consistent and reliable.
It is easy to blow and cannot be overblown. The harder you blow, the louder the sound. Chambers are designed to self-clear when submerged in water. Will be heard above ambient noise, loud crowds, the roar of engines, breaking waves and thundering gale-force winds
