Acme Alpha Dog Whistle 210.5

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. You only have to breath into it for a quality sound enabling you to produce commands so quiet they are almost inaudible to people - perfect for close working dogs. The ALPHA 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.
