The ALPHA from ACME has been developed over four years in collaboration with World Champion trainers to create an unrivalled whistle.
 
Patented sound chambers offer a more efficient use of air. That means brighter sound giving you better command and a more responsive dog, close- to and over distance. They are effortless to blow and, because of that, give you the greatest flexibility to vary your breath, your whistling style and your choice of commands.
 
The all over comfort grip offers softness in the mouth and perfect handling in all conditions.
