Electronic Whistles

One press. One tone. The play stops.

The electronic whistle every modern official keeps in reserve. Three-tone settings, rechargeable batteries, and the loudness that cuts through HVAC, crowd noise, and indoor gym roar.

  • Fox 40 rechargeable for high-volume indoor work.
  • Fox 40 three-tone for crews running multiple official signals.
  • Mini and full-size options to match how you carry.

The whistle of choice for officials who cover four sports a year.
