ACME 211.5 dog whistle with whistle band

5700Hz FREQUENCY - DESIGNED FOR LONG-DISTANCE RETRIEVER AND LABRADOR RECALL - The ACME 211.5 Classic is precision-tuned to 5700Hz, a lower frequency than the 210.5 that projects significantly further across open terrain. Purpose-built for Labrador and Golden Retriever work on flat ground, coastal environments, moorland, and open fields where dogs work at distance from the handler. PEALESS AND WEATHERPROOF - SAME PERFORMANCE IN ALL CONDITIONS - The 211.5 Classic contains no pea to freeze in frost, stick in rain, or produce variable output as conditions change. The same clear 5700Hz command leaves the whistle in driving coastal rain and on a dry summer training ground - a practical requirement for any handler who works their dog year-round outdoors. UNIFORM SOUND REGARDLESS OF BLOW STRENGTH - FASTER RECALL CONDITIONING - The 211.5 Classic produces the same pitch whether blown hard or softly. This fixed-frequency consistency is the professional standard in gundog training - your Labrador or Retriever is conditioned to a precise audio cue, not an approximation that varies with handler effort or fatigue. CUTS THROUGH WIND AND WAVES - RELIABLE ON COASTAL AND OPEN TERRAIN - The 5700Hz frequency carries further and holds its audibility in exposed conditions better than higher-pitched alternatives. On beaches, open moorland, and coastal ground where retrievers characteristically work, the 211.5 delivers commands where the 210.5 begins to fall short. WORKS WITH ALL BREEDS - PROVEN FOR RETRIEVERS AND LABRADORS - While the 211.5 is the established retriever and Labrador frequency, its consistent projection works effectively with dogs of all breeds and ages. Any handler who needs longer-range recall or works in open terrain can rely on the 211.5 regardless of breed.
