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. CUTS THROUGH WIND AND WAVES ON COASTAL AND OPEN TERRAIN: The lower 5700Hz pitch is specifically more effective in windy and open conditions than higher-frequency alternatives. On a beach, exposed moorland, or open parkland, the 211.5 Alpha maintains its audibility where a 210.5 or higher whistle frequency loses projection distance. COMPACT AND POCKET-READY: Supplied without lanyard for handlers who prefer to carry their whistle in a vest, jacket, or trouser pocket. Accepts any standard ACME lanyard (available separately) for hands-free carry when required. PEALESS DESIGN, WEATHERPROOF AND CONSISTENT IN ALL CONDITIONS: No pea to freeze, stick, or produce variable output in cold, rain, or heavy field conditions. The 211.5 Alpha delivers the same clear command in winter gales and summer heat, essential for dogs working in the full range of conditions British retrievers are expected to handle. USED BY PROFESSIONAL RETRIEVER TRIAL HANDLERS: The 211.5 frequency appears at working tests, field trials, and on driven shoots carried by handlers who need their commands to reach dogs at marking distance. The 211.5 Alpha's superior build quality and frequency stability make the ACME Alpha 211.5 dog whistle the choice for handlers who require more precision than a standard Classic body provides. UK DESIGNED AND MANUFACTURED, ACME WHISTLES, BIRMINGHAM SINCE 1870: The 212 Pro-Trialer carries ACME's heritage of acoustic precision, manufactured in Birmingham to the same standards as the 210.5 and 211.5, extended to a lower frequency for wider-ranging field applications.
