Fox 40

The Fox 40 Pealess Whistle was a success from the first time it was used professionally, at the 1987 Pan Am Games in Indianapolis, Indiana. The pealess whistle has become the whistle of choice for the National Hockey League (NHL), the National Basketball Association (NBA), the National Collegiate Athletic Association (NCAA), the National Football League (NFL), the Arena Football League (AFL) and the Canadian Football League (CFL). Fox 40 Pealess Whistles have since been used in numerous world-class tournaments, such as the Olympics and the World Cup.
