## Description

Acme 636 Whistle

## Features

- LOUD: The whistle is one of the loudest in the world. You can reach tones up to 4000 Hz with this model. This gives you an enormous range that can still be heard kilometres away.
- CONSTRUCTION: The whistle has three air chambers, which allow the sounds to overlap and produce the incredible volume. The special thing about this model is that it does not have a pea like traditional whistles, so the whistle cannot be overblown.
- DESIGN: The whistle is small, thin and very light, so it can be attached to a bunch of keys without any problems. Thanks to its bright orange colour you cannot lose it easily. The colour also stands for emergency.
- USE: It is used in many different sectors. Whether as a safety whistle attached to trekking backpacks, life jackets, as a referee whistle, as a training whistle in various sports or as a dog whistle, it has many uses.
- ORIGIN: In the past this safety whistle was attached to every life jacket in order to be prepared for an emergency as it is waterproof and can therefore be used in any situation.

## Questions & Answers

**Q: Will it still work if it gets wet?**
A: I just tried it and yes, it worked wet. 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.
