Very loud - my ears are ringing after blowing it, and I like the pain
Floats - obviously good for in a pool
Looks like a vape pen - a patron asked me to not vape around her children, I replied by blowing the whistle at a running child
No good way to hold it - it is quite difficult to have a firm grasp and still be able to have all the sound come out
Mouthpiece - it's difficult to get a good seal on the whistle and still blow through it hard, I also have to clamp down on it with my teeth which isn't comfortable
The full sound is directed to the side - most times the whistle is louder to the side
All in all it is a very loud whistle, even louder than the air horns we often use. But, for my application it's not suitable for everyday use. It would however, be perfect for an emergency whistle.
I had tried everything- fox 40, storm, etc. I hadn't tried the Hyperwhistle yet because it looked too large and ungainly. Finally I was out of alternatives so I ordered one.
OK...this thing is loud. Crazy loud. Any reviewer who claims otherwise or compares its volume unfavorably to any other whistle on Amazon as of the date of this writing is lying. No doubt about it.
In fact, simply angle the mouthpiece into the relative wind during freefall and I think they can probably hear it on the ISS. LOUD. Seriously.
Will it ever become a standard part of a skydiver's kit? I don't know...it's still very loud up there, while it can be heard, it doesn't have the volume to get your attention unless you're specifically listening for it. Now, once you're under canopy, you can hear each other a looong ways away- certainly further than 2 miles!
The HyperWhistle is a game changer. There was a fight on Wednesday. I hit the afterburners to stop it. I blew the whistle when I was about 7 feet and closing from the fighting students. They were so shocked by how LOUD the whistle was they stopped fighting!!! I tried to take both students by the hand to the office. One resisted. I hit the whistle again and got her hand when she went to cover her ears.
It came down to they would rather walk quietly to the principal's office than hear me blow the whistle a third time. A discipline referral is better than a hospital referral.
***Jan 28, 2019 I still stand bye my original recommendation. I have broken up quite a few fights with it. The students know the sound and it has the recognition that you don't want to be near it. It puts ANY rape whistle to shame. If someone is near you and you don't want them to be this whistle will deliver that message.
The worst part is I bought two. what a mistake.
