Genuine ACME Professional, BPA-Free Plastic Dog Training Whistle No. 211.5 ALPHA with Enhanced Ergonomic Grip, 110 dBA Long Range, Made in the UK. Black on Day Glow Green

PRECISION-TUNED AT 5700Hz FOR RETRIEVER AND LABRADOR TRAINING: The ACME 211.5 Alpha is engineered at 5700Hz, a lower frequency than the 210.5 that projects significantly further across open terrain. It is the recognised choice for Labrador and Golden Retriever handlers working flat ground, coastal environments, open moorland, and stubble fields where dogs range at distance. MAXIMUM AIR EFFICIENCY, QUIET LONG-DISTANCE COMMANDS WITH LESS EFFORT: The 211.5 Alpha's patented sound chamber design and frequency profile allow handlers to produce a strong, clear recall signal without hard blowing. Long-distance commands reach a dog 80 to 100 metres out from a relaxed, controlled breath, quieter at the handler's end, clearer at the dog's. ALL-WEATHER ALPHA GRIP, BUILT FOR FIELD CONDITIONS: The Alpha's textured, ergonomic soft-touch body holds securely in wet gloves, muddy conditions, and cold weather. The grip is designed for outdoor working environments where a conventional smooth-body whistle becomes slippery at exactly the moment you need a precise command. MORE STABLE FREQUENCY, SUPERIOR CONSISTENCY FOR FASTER CONDITIONING: The 211.5 Alpha produces the same 5700Hz pitch on every blow, with less variation from effort or conditions than comparable whistles. This stability is what accelerates recall conditioning, your Labrador or Retriever learns a precise, consistent audio cue, building a faster response over fewer training sessions. The ACME 211.5 dog whistle is built for handlers who need reliable dog whistles for recall at long distances. OPTIMISED FOR RETRIEVERS AND LABRADORS, WORKS WITH ALL BREEDS: Although tuned and recognised for Retriever and Labrador training at 5700Hz, the 211.5 Alpha works successfully with dogs of all breeds and ages. HPR breeds, Vizslas, Spaniels needing longer-distance commands, and crossbreeds all respond effectively to the 211.5's clear, far-carrying frequency.
