Sonik Blast whistle (orange black)

Good safety whistle to keep in a backpack or when boating/kayaking. Bright colored & it doesn’t take much wind to make it sing. Very functional tool to have in the pack. Solid construction & good value for the money.

I use this for dog training. Gets their attention rather than using an e-collar.

It's a whistle. It blows.

This thing works - - much louder than you might think. I have a few around, to put in my handbag or attach to my coat.

Could be too loud. Kind of annoying when riding a bike.

My favorite whistles for roller derby!

Super loud and works great!

I recently started working as a soccer referee. After my mentor watched one of my games, he pointed out that my whistle was too quiet. That night, I ordered a Fox 40, and it arrived very quickly. I like the orange color because it’s easy to see. The sound—oh my gosh—I almost deafened myself on the first try. It’s much louder than I expected. I’ve been using it in my games since then, and officiating has become much easier with the proper tool.
