ACME Alpha 211.5 Professional Dog Training Whistle – Long Range, 5400 Hz, UK Made

Overview

The ACME Alpha 211.5 is built for trainers who value range, reliability, and ergonomic comfort. Made in the UK, this whistle combines classic acoustics with modern refinements to support clear communication during training sessions, whether indoors, in the park, or at the field.

What you gain with longer range and bright sound

Compared with the 210.5, this model delivers a longer reach—roughly 450 to 500 yards—allowing you to cue a dog at greater distances. The patented sound chambers use air efficiently, producing a brighter tone that helps your dog perceive your call in a variety of outdoor environments.

Consistency you can rely on

Standardized frequency of 5400 Hz means your dog can learn to recognize the signal across different handlers. Whether you’re training alone, with a partner, or with a dog walker, this standard helps your dog respond consistently to the same cue.

Quality you can feel and trust

The whistle is made from BPA-free plastic that meets food-grade standards. The redesigned all-over ergonomic grip feels soft in the mouth and provides confident handling in rain, mud, or sun. Every unit is genuine ACME, developed and tested in the UK with deep expertise.

• Long-range performance: encourages recall and distant guidance without shouting
• Brighter sound reduces ambiguity in noisy outdoor spaces
• Standardized frequency aids quick association and consistency
• BPA-free, food-grade materials for safer daily use
• Weatherproof construction supports year-round training
