When training calls need to be heard across a field or during outdoor work, a whistle offers a distinct cue that can be used at close range and farther away. The Alpha 211.5 is preferred for Labrador, Retriever, Collie, Greyhound and other larger breeds. Its standardized tone also helps keep the cue consistent when more than one person handles the dog.

How far does the ACME Alpha 211.5 carry?

Its approximate range is 450–500 yards, and it reaches farther than the ACME 210.5. The sound chambers are designed to make efficient use of the air blown through the whistle, producing a brighter signal that supports commands at close range and over distance.

• Developed over four years with World Champion dog trainers.
• Designed for clearer command cues and a more responsive dog.

Will the whistle give different handlers the same cue?

Yes. The ACME Alpha 211.5 maintains a standardized 5400 Hz frequency, so the whistle signal stays consistent when different people use it. ACME notes that dogs recognize the call regardless of who is blowing the whistle.

• Different whistle colors can help distinguish the whistles used by a partner, family member or dog walker.
• This version is magenta pink.
