Sounded quite loud. Another whistle that is very loud even when wet is The Acme Thunderer (made in England) also available at Amazon. It once saved my life in a scuba diving accident. While floundering in the ocean, I blew SOS and was heard all the way to shore; several miles away. I was rescued as a result. Still cherish that Acme Thunderer. **Q: Ben, is the whistle loud? : - )** A: As loud as Fox 40 Classic with a slightly higher pitch. I love this whistle for my training sessions and refereeing on the pitch. **Q: Does this come on lanyard?** A: This particular item does not come with a lanyard. Thanks! **Q: Will this whistle work if it's wet?** A: This whistle doesn't have a ball in the device. In my opinion, it should work when wet. Even if a little water was inside, just blowing the whistle should clear any moisture out of same. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Referee's whistle. *by M***S on 7 January 2026* Great whistle, very loud, would buy again. ### ⭐⭐⭐⭐⭐ Small but loud *by E***R on 25 May 2023* Compact version of the original Tornado - handy and still very loud - great for refereeing or signalling. ### ⭐⭐⭐⭐⭐ Great whistle *by R***S on 5 October 2019* Used for school.
