Fox FO9513-BRK Micro 40 Whistle, One Size

I bought this whistle after reading a recommendation on a survival forum. I went looking because my old go-to emergency whistle had broken unexpectedly. Which was a bit shocking. I mean, what good is a metal whistle if there’s a little soft plastic piece inside that can shift and make the whistle unusable when you need it to work?Long story short this whistle is all one-piece, so there aren’t any failure points, it’s small enough for pocket carry, and loud enough that it literally hurt my ears when I was testing it. Waaay louder than my last emergency whistle. 5/5

I found this whistle from dog trainers who call their pups with it. So I tried it on the soccer field. Pea less, so does not clog. Works great. The only positive/negative is the sound goes out the sides (rather than the normal "up" - gets the players' attention, but also goes directly into your ears! Always nice to have an alternative sound to the referee on the next field; this is it. Also carries nicely in the pocket for backup when you drop your main whistle(s).

Very loud and light weight.

I got this for dog training and it works wonderfully!

I love that came in a sealed package. When I use it I ll update with a video to show how much loud it’s…

My wife is a teacher and uses this maybe twice a day during the school year. She was going by a chair and lightly brushed it--the part that goes on the keychain broke! I bought 2 of these and never opened the 2nd one. Months later, I can't send either back. I may put packing tape on the new one to reinforce the cheap plastic these whistles are made with.

Not loud

Great whistle. I wish the lanyard wasn't as rigid but that can easily be changed. Whistle sound is loud and clear.
