The new ACME ALPHA 210.5 and 211.5 are the direct further development of the classic 210.5 and 211.5 and are characterized by the following points:
-
Even greater reach
Up to 17% more reach, which significantly increases the possible working distances.
-
better response
The frequencies generated by the ALPHA are concentrated in the middle octave range of the dog's hearing so that the dog can hear them more clearly.
-
Sharper sound
The ALPHA is 8 % louder and has a sharper sound that is even easier for the dog to interpret.
-
Four years of development
Extensive research and development work was carried out in collaboration with the best dog trainers in the world to develop the best dog whistle in the world.
It is easy to switch from the classic 210.5 and 211.5 pipes to the ALPHA models, as they still have standardized frequencies.
