Genuine ACME Professional Quality BPA Free Plastic No. 635 Tornado AIRFAST Whistle, medium sized, High-pitch, pealess, 117 dBA, Designed and Made in The UK. Black

As a soccer official I have used the Fox 40 and the Dolphin. The unique tone has a 3rd lower frequency which allows players to differentiate from other fields during a tournament. It still carries around the field and in a pinch will stop players in their tracks if blown at full volume.

Excellent whistle. Been using it for years, just got to stop losing them. This is my third one I've had to buy in 11 years. It's loud, authoritative, and thankfully it points away from me so my ears don't absorb the loudness. Cannot say enough good things about this product, and the Acme corporation in England. The English make great whistles, especially this one. It's no wonder it's one of their most popular sellers. Many soccer referees I work with use this whistle as well.

My husband's review: "I've officiated soccer for many years at youth and high school levels. This whistle has the best sound of the 15 or so whistles I've used over the years. The three-tone set up cuts through all sorts of background noises and conveys' authority. A dandy design. "

*TL:DR*This is a LOUD PEALESS whistle. Emphasis on the PEALESS. It is a single tone whistle because it has no 'pea' in it. If you are looking for a loud single tone whistle, this is the one.*PROS*# Loud# Sturdy (but plastic)# Lanyard friendly# Reasonably priced (this is not a made in China product)# The whistle always works because there is no pea; no accidental blockage of sound.*CONS*# No Pea - children tend to respond better when the whistle has a shrill / varying tone. But, I can't blame the product for this; its clear, the whistle is pealess.# Plastic construction. Some may not like it and it may feel fragile (but its not).# Need to blow quite hard to get optimum results.# No lanyard included.# It can be quite loud and sometimes my ears ring!*Conclusion*Its a good loud whistle. I recommend it.

This is a great whistle to have when you are refereeing games in a complex where multiple games are going on at the same time. Up close it sounds like pretty much evety other pealess whistle, but once you move away you get a little more of a hollow train whistle sound. It is distinct and essy to pick up. Like other pealess whistles, the harder you blow the louder it gets. I love the design and sound.

AWSOME...I AM A SOCCER REFEREE ...AND IT SEEMED ,,UNTIL NOW THAT THERE WERE ONLY TWO EFFECTIVE SOUND SPECTRUMI HAVE TRIED A LOT OF WHISTLES ,,,,SOME ARE HARDER TO LEARN THAN OTHERS.....THIS ACME WHISTLE IS NOT ONLY LOUD BUT A UNIQUE PITCH,,,PLUS EASY TO USE...GREAT PRODUCT...

The whistle works great I recommend this product to all referees and couches has a great sound, you are sure to make your presence known with this whistle.
