About this item
- ADJUSTABLE FREQUENCY SILENT DOG WHISTLE: The ACME 535 produces a tone humans can barely hear, yet travels over 1.5km. Adjust frequency via the screw piston mechanism to find the precise pitch your dog responds to best. Special air directors tightly control the frequency, generating maximum sound with minimal effort. Suitable for all breeds and all training levels.
- FOR ALL BREEDS FROM PUPPIES TO WORKING DOGS: The adjustable frequency makes the ACME 535 suitable for any breed, from puppies learning recall to established working dogs. Owners, trainers and handlers use the 535 to train discretely in public spaces without disturbing bystanders. For dolphins, the 535 has also been used in professional marine animal training.
- SOLID BRASS CONSTRUCTION - ALL BREEDS: The ACME 535 adjustable silent whistle suits every breed from puppies to established working dogs. The screw piston mechanism allows frequency tuning to find the optimal pitch for your individual dog. Produced from solid brass at ACME's Birmingham factory. Available with brown leather lanyard 107 for hands-free carry.
- PAIRS WITH A BROWN LEATHER LANYARD: This listing includes the ACME 107 brown leather lanyard for secure neck carry. For a complete recall and positive reinforcement system, pair with the ACME 210.5 or 211.5 Alpha for audible commands, and the ACME Clicker 470 for marker training. All available from ACME's full range of British-made training accessories.
- ART DECO DESIGN, MADE IN ENGLAND SINCE 1870: The 535 form was conceived by Clifford Hudson, son of ACME founder Joseph, drawing on Art Deco styling. Solid brass construction designed to last decades. ACME has manufactured whistles in Birmingham since 1870. Five generations of family ownership. Used by professional trainers and handlers worldwide.
- HOW TO ADJUST AND USE THE 535: Screw the piston in or out to change the frequency. Test each setting with your dog and note the position that produces the strongest recall response. Use short pips for recall once the correct frequency is found. The brown leather lanyard (included) provides hands-free carry. Comes with printed instructions and training guide.
- SOLID BRASS FINISH - ADJUSTABLE FREQUENCY: Brass construction gives a durable, long-lasting finish. Adjustable screw piston allows custom frequency tuning for any breed. Available in nickel plated, polished brass, antique brass, silver plated, rose gold and gold plated finishes from ACME's full range.
- COMPLETE YOUR TRAINING SYSTEM: The 535 Silent Whistle pairs with the ACME 210.5 or 211.5 Alpha for a combined audible and silent recall programme. Add the ACME Clicker 470 for positive reinforcement marker training. The 535 is also available in nickel plated, polished brass, silver plated, rose gold and gold plated finishes in the ACME prestige range.
- SOLID BRASS CONSTRUCTION, ART DECO HERITAGE: Made from solid brass to an Art Deco design by Clifford Hudson, son of ACME founder Joseph Hudson. Still produced using original tooling at the Birmingham factory. ACME has manufactured from the same site since 1870. Five generations. A whistle built to last a lifetime. Presentation box options available.
- CARRIES OVER 1.5KM, INAUDIBLE TO HUMANS: Special air directors generate a sound that travels over 1.5km with minimal breath effort, while remaining virtually inaudible to the human ear.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
