ACME Emergency and signal whistle Tornado T2000 with whistle band (black/black).

Loud: thanks to the three air outlets, this pipe is one of the loudest pipes in the world. With its 122 dB, it can still be heard and perceived well in extreme distances. Range: the whistle produces so-called high-frequency tones that can overtone many sounds and also overtone loud background noise. Sport: especially in sports - as a referee - you must also be able to draw attention with many background noises. No longer a problem with this whistle. Whistle: This model is a shrill whistle that produces very loud sounds without a triller. This means that no trill ball can jam and the whistle can be used even in heavy rain. Lightweight: thanks to the light weight of only 10 grams, the whistle can be easily attached to the key chain or a backpack and carried with you.
