About
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.
