For dog training, a whistle gives handlers a consistent way to call and cue a dog without relying on spoken commands alone. The Alpha 211.5 is aimed at owners and trainers working with larger breeds, including Labradors, Retrievers, Collies and Greyhounds. Its Baby Blue on Yellow colorway also makes it easy to distinguish from other whistles.

How far can the ACME Alpha 211.5 reach?

The ACME Alpha 211.5 has an approximate range of 450–500 yards and reaches farther than the 210.5 model. Its patented chambers make efficient use of the air blown through the whistle, creating a brighter sound intended to carry both nearby and over distance. ACME connects this sound design with improved command response from the dog.

• Sound chamber design developed in collaboration with World Champion dog trainers.
• Preferred for Labradors, Retrievers, Collies, Greyhounds and other larger breeds.

A standardized frequency means a dog can recognize the whistle call even when different people use their own whistle.

• Suitable for use by a handler, family member, partner or dog walker.
• The frequency stays consistent across different whistle colors, so handlers can choose distinct colors.
