Fox 40 Sonik Blast

Great! Loud and gets the job done.

Perfect for lifeguards! The adjustable neck piece is perfect so it doesn't come off in the water and the pull-away piece makes removal very quick in emergencies! Nice material that doesn't get mildew inside.

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.

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

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).

Very good whistle and good sound.

Ok, so I bought this for school. I substitute teach full time and today's kids are, well, little angels. I can't raise my voice real loud due to a medical thing. I originally thought I was being smart when I started at a new district (Middle School my first day) and brought a referee whistle with me. Boy way I wrong. Almost every teacher had a whistle hanging from their ID lanyard. Fast forward to my first "wonderful" bunch of students. I had to use my whistle because raising my voice did nothing to the 4th graders. A girl actually walked up to me and said they weren't going to do what I say because they don't fear me like a regular teacher because I really can't punish them. At least they are honest. Needless to say the whistle was basically useless. They ignored it. I searched Amazon and found this whistle. I found a few other teacher reviews that said this was perfect so I bought it. I have only used it once. When I did it worked perfect. The class immediately stopped acting up. There were a few yelling Ahhh!, but that was the point. I didn't blow it full force because I was indoors and that would be too loud. Three boys actually asked "Was that a Fox 40?". They knew about this whistle. I now only have to say "Don't make me blow my whistle" to any class in the school. Make sure to plug your own ears before using it. I didn't and my ears rang for a bit.

Muy bueno

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.

super sifflet, très efficace et puissant. on m'entant sans problème même avec la foule dans les gymnases et même en soufflant peu dedans. je recommande

I am a lifeguard and this whistle is perfect as it is by far the loudest one in a very busy pool, all other lifeguards asking which one it is because it's so good. Had this for 3 months of high intensity use and showing no signs of wear or performance drop
