Fox40 whistles are used by professional referees from the world's most prestigious leagues and organizations, such as the NFL, NHL, NBA, FIFA, FIBA, NCAA, and many, many others! Fox40 was founded by Ron Foxcroft, a former renowned basketball referee. After an incident during the final game of the Montreal Olympics (a Yugoslav player fouled a U.S. player, and referee Foxcroft attempted to call the foul, his traditional ball whistle malfunctioned, preventing him from doing so). He decided to design a better whistle. In 1987, he unveiled a whistle without a ball. Color: black
