High pitch, quiet to users, fitted with a weatherproof pea to provide the famous Acme trill of rolling notes or a variable frequency. A great whistle for close work and a different style of sound for a different command.
These whistles are extremely durable and their tone is independent from the influence of the weather. Due to the standardized frequency, the desired frequency can be ordered any time.
Thanks to inbuilt water-resistant ball the whistle ACME 210 has clear trill tone in frequency at about 750 Hz.
In packaging is a whistle lanyard with matching color.
