Sonik Blast Whistle

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

Great whistle and very loud which is good. Definitely worth buying

Great item. Staff in a school setting. The kids hate it, but it focuses their attention.

As a new PE teacher my daughter needed a whistle, she wanted a red one. Read lots of reviews both on Amazon & elsewhere 'Fox 40 Sonic Blast' always came at the top, found it in red on Amazon so brought it as a gift. She absolutely loves it, so loud that all the kids stop even at a busy lunch time in the playground. It's so good the other long standing PE teachers have dumped off their cheap whistles & brought one.

Haven’t had the opportunity to use it yet but it’s loud

This is a great whistle, and am glad I purchased it. Only minor issue was that the Breakaway Lanyard was not included in the package, but I have been in contact with the seller and they will send one out.

This is a bright colour and gives me the chance to stand out on the field! The protective mouthpiece feels comfortable in the mouth and the pitch of the whistle is ideal for louder events (I referee in football stadiums). I find this slightly easier to blow than other comparable whistles (Fox 40 classic I cannot get on with for example). I find this whistle allows a variation of tone, but doesn't 'die' out mind blow.

Brilliant - Loud - Dependable for all my Mountain Trekking

it is ok

防犯目的で購入。 軽く吹いただけでもかなり大きい音が出るので震災や強盗の場面でも役に立つと思います。

小学生のサッカーの審判をやることになったので大きな音が出るホイッスルを探していました。 ドルフィンプロKPだと音がカスれやすかったのですが、こちらの商品はカスれにくく、音が大きいのでおすすめです。

吹きやすく、しっかり響く音で使いやすいです。
