The Fox 40 Safety Whistle is a super loud pea-less whistle that you can use as a signaling device to get someones attention in case you find yourself in trouble. Small enough to fit in the pocket of your PFD, or even a shirt pocket, the Fox 40 Safety Whistle is a key piece of safety equipment that every paddler should carry with them.
I've had and do have other whistles; but, this one beats them all and I may change the others out. Someone who knows more about these things than I do may know why it is that the whistles with the moveable thing inside (called a pea, I think) are definitely not as loud at all. This Fox whistle is so loud it actually is tough on Your own ears when it's blown. That's not a problem as I see it as the sound is off short duration and if You're in trouble You want to be heard. This Model will definitely do the trick for You! It's inexpensive and light. This is the one to get.
It's pretty loud and sure to get attention. BUT...it seems that you have to breath into it fairly hard to get it loud. Makes me wonder if someone who is in serious trouble would have the ability to really blow that hard into it.
Nice loud whistle, better than the type we used before.
I like it, that sucker sure is loud
