Acme Tornado Slimline No. 636 Signal Whistle and Emergency Call Whistle (Signal Yellow)

• Loud: The whistle is one of the loudest whistles in the world. You can achieve tones of up to 4000 Hz with this model. This allows you to achieve an enormous range that can still be heard even in kilometres.
• Construction: It has three air outlets, which makes the volume distributed well. The special feature is that this model does not have a ball like conventional whistles.
• Design: the whistle is small, thin and very light. So it can be attached to a key chain without any problems. Thanks to the bright colour in bright orange, you can find them anywhere. At the same time, it symbolises the emergency.
• Use: it is used in many different fields. Whether as a rescue whistle on trekking backpacks, on life jackets, as a referee whistle, as a training whistle in various sports or as a dog whistle you will find frequent use.
• Origin: In the past, this rescue whistle was attached to any life jacket, as it is waterproof, and can therefore be used in any situation.

Slimline, small and flat, loud and high pitched. The little whistle with a big punch.
