The best whistle
I tested this against several other whistles. It's very loud, but not much more than other whistles; pretty much all decent whistles are about the same in loudness. But the Fox 40 is compact and the mouthpiece design is perfect where you can blow the whistle without having to hold it to your mouth. Loud, compact, easy to use, makes it the perfect whistle.

It’s Loud
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.

LOUD!!!
Excellent product. Tough, lightweight, and super loud. It's great that you can hold it easily between your teeth, because you're going to need your hands to cover your ears when you blast this thing.
