Superior performance combined with superior comfort! The premium Sonik Blast CMG Pealess Referee Whistle from Fox 40 provides additional comfort for holding the whistle in the mouth. Distinct louder pitched whistle provides a more powerful sound, without a lot of effort, which is easily heard over the crowds. Ideal for large outdoor arenas with large crowds and ambient noise. The CMG is perfect to reliably hold the whistle in mouth or fingers in wet conditions.


  • Design: 2-chamber/4 resonators; pealess
  • Sound power: exceeds 120 dB

Used for football. Did not care for the tone/sound. It'll stay in my bag only be used as an emergency backup whistle to my backup whistle.
