The Fox 40 C4 is our original 3-chamber pealess whistle producing 115 decibel sound. The omni-directional sound will never fail and can be heard up to a mile away. If you can't be seen, ensure the accessory you carry allows you to be heard. This popular model is used in a variety of industries including sports, education, health care and emergency services, traffic control, industrial signaling, personal safety, camping and outdoors, as well as pet training.
