Sonik Blast

Great wistle. Worked great. Yes, it is very loud!

Very good whistle and good sound.

I had a Fox 40 that I loved for getting the attention of 150 loud kids. I thought I lost it. Went on Amazon to purchase another and came across the Fox 40 Sonic Blast. I wanted something louder and boy did it deliver. It's actually TOO LOUD. So loud that it hurts my own ears when I blow it. I believe this would be great for boating, hiking, putting into an emergency kit, maybe for emergency crews trying to find lost people, etc. Definitely for outdoor use. I can see it being great for emergencies, when you aren't using it all the time. I would not recommend using this frequently, such as for sports. It's just too loud. I would recommend using ear pro with this whistle. This will be going into a backpack for hiking and I'll be going back to the original Fox 40.

It is a loud whistle and I buy these repeatedly. I bite down on whistles. I think it could be due to the stress of coaches yelling as on occasion they do not agree with my calls as an official?? I do crack them after months of use but that is not the fault of the craftsmanship. I am sure this is not the best whistle on the market but a superior whistle would cost far more. In a nutshell, this is best whistle you can purchase for the price. It is the loudest whistle I have purchased and I have purchased quite of few brands. I highly recommend this whistle. Remember to not bite down on them and if you are an official, don't allow the rowdy coaches, and on occasion, the occasional rowdy parent to stress you out.

I bought the cheapest color they had at the time. Would have rather had a normal black whistle... But it was almost twice as much at the time... Fine gimme white. If I could have had black for the same price I'd have given it 5 stars. It is really loud and you don't have to blow very hard to get a VERY loud whistle. It is also seemingly impossible to overblow. I tend to overblow a ton; so the cheap 5 packs for $3 at the sporting goods store just doesn't do me any favors. I'd buy it again... I'd buy one for my whole staff if they were $4 each instead of $7-15. As I write this they are grouped tighter in price but it is still annoying ($8.38 - $13.11).

Works great! Loud and clear for in the gym and one the recess yard.

Sharp and loud

I’ve been reffing soccer games for 5 years, and this is probably the best whistle I’ve ever used. To start with the lanyard is a great quality lanyard, thick and feels good quality, not just a normal cheap lanyard. Additionally, the whistle is EXTREMELY loud. High pitched and I guarantee you the players will hear this whistle for sure. The mouth grip on it adds something to it, I can’t pin point what it is but it just feels good lol.

Try it

After purchased, it takes very long duration, got frustrated but After I realized that I ordered a Foreign Product, I just wait for Delivery. It reached before the Time, I really Liked the product, very smooth and Sharp sound.
