Flawless, consistent and penetrating sound keeps the referee in control of the game. Standard choice for personal safety and rescue professionals worldwide!

There are no moving parts to freeze, jam or deteriorate. Whistle is available in multiple colors and has an 115dB sound rating. Included with the whistle is a breakaway lanyard.
