As the worldwide leader in whistle technology, Fox 40 set out to develop a new whistle for the ever-changing demands in stadium and safety arenas worldwide. They looked at their bestselling whistles; the Fox 40® Classic® and the Fox 40 Sonik Blast®.

Two of the Fuziun’s ultra-high frequency chambers cut through crowd noise, while the frequency of the lower chamber commands attention!

The dependable piercing ultra high frequencies of the Classic’s upper chambers penetrate crowd and background noise in any situation.

The lower chamber of the Sonik Blast generates a powerful and penetrating lower frequency to carry over longer distances.

Fuzing these two designs, along with the patented Fox 40 CMG® comfort mouth grip, finalized the whistle with a perfect sound and feel, creating optimal sound power.

It is a bigger whistle than I usually have. It sounds nice but would be better if was a little bit smaller.

I actually really like this referee whistle. Yes, it takes a good amount of air to blow but it's pretty loud and I love the CMG! It's not my absolute favorite, but I still like it.

Best suited for indoor activities since pitch is somewhat high but appreciate that I can feel comfortable blowing it in either position (up or down) due to its shape.
