helps you aid police in deterring or preventing crime in your neighborhood, or call for help if you’re lost, sick, or injured.

   The Defender™ is the exactly same whistle American Whistle Corporation makes for the National Fraternal Order of Police.

   The Defender™ can signal your need for help, frighten away someone who means you harm, or alert neighbors to call the police.


The piercing, distinctive blast of a truly good whistle can scare away attackers and bring people running to a victim’s aid.  Yet a whistle cannot be turned against a victim, as weapons can.

Campuses like the University of Colorado and the University of Illinois have initiated long-term Whistle Defense programs using the American Defender™ personal safety whistle.
