Acme Whistle Thunderer

A whistle made by perhaps the most respected company of it's kind in the world, high quality British product! In my opinion this the best whistle you can buy. Very high build quality, which is good enough for even the most demanding customers, and there are very demanding people using this: olympic referees, military, etc!
The sound is VERY loud, make sure to protect your ears before using this!

Real thunder, great material, this is the best in the world
