Acme Alpha Whistle 211.5

Working Dog Whistle

The ALPHA is the most efficient whistle ever made. Its frequencies generated are now concentrated in the dog’s middle octave hearing range, enabling the dog to hear with more clarity. Its contemporary design encompasses a new comfort grip in the hand and mouth, it is easier to use and produces a far greater variety of whistling sounds and styles so owners can communicate effectively with their dog, helping to maintain control.
