Loud and comfortable fit
Very versatile and can be used on either hand. Easy to blow and very loud whistle. The fit is good and have never had an issue of it falling off during a game. Seems like good quality material and should last.

Great Whistle
Relatively cheap, loud as heck (don’t blow it too close to anyone’s ears), easy to clean, and I personally like keeping my whistle in my pocket and then being able to finger mount it for certain drills. The classic neck hanging whistle just doesn’t work for me.

Whistle blaster!!!
My husband and son are new little league and high school referees and these whistles are game changers! I didn't know a whistle could be so loud. They are perfect for officiating!!!

Good grip and simple design
The fingergrip is what makes this whistle stand out from a basic one, especially if you want something that is easy to hold during practice or games. The pealess design keeps things simple, and the black finish looks clean. Practical overall, though the grip style may not be for everyone.

It’s great! You will need hearing protection using this whistle
What the heck!!!! This thing is insanely loud! I have a decibel meter that I will use for work to see if I need earplugs for safety reasons so I thought I’d give it a test with the whistle. All I have to say is …………………..I can’t hear now lol. The first time I blew the whistle, it hit 115 decibels. The second time I did it, I got 118 and I was not going full lung power. And I don’t want to without some hearing protection. See the picture for the decibel reading, but I am very happy with this whistle and plan to use it for soccer coaching. I think it will reach around the whole field and yes, the pitch is very distinctive! Still working strong several soccer games in. Also gave it another test to see just how loud I could get it. 126 decibels is astonishing to say the least. I can still co trol the volume and not go loud if needed.

Great whistle, the best you can get for the money.
Fox 40 Sonic Blast is probably the best whistle for the money. It is easy to modulate and extremely loud. It has a high quality sound to it, not too high and not too low, that gets the attention of everyone on the field. I own quite a few whistles that I use on regular basis, below is my recommendation based on my my personal observation. 1. Fox 40 Sonic Blast – extremely loud with good sound quality. Great for outdoor, too loud for indoor. 2. Fox 40 Pearl – Not very loud but has a deeper sound than other whistles that I have used, other than Caul. Great for Indoor, will do on a small field outdoor. 3. Acme Tornado – Quite loud and with good sound but the fingergrip mechanism is crap. Good overall for both indoor and outdoor. 4. Molten Delux – As loud as Acme Tornado, but is sounds a bit cheap, plus it does not have a fingergrip mechanism that I prefer. Good for both indoor and outdoor. 5. Fox 40 Classic – As loud as Acme Tornado, but with a much higher pitch. (Too many referees use this whistle on the pitch, indoor and outdoor, but it is quite a good whistle.) 6. Fox 40 Caul – As loud as the Pear but with a deeper tone. (It sounds loud to me, but from personal experience it is not heard easily on the field. I wrote a review of this whistle on Amazon.) Not recommended.
