Engineered to be inaudible to humans yet loud for dogs, it features a unique audible confirmation tone to ensure proper function. Lightweight, durable, and portable with a protective end cap, this whistle is a professional-grade tool for effective behavioral control and training. ## Description The 535 whistle has a variable single frequency between 5200 and 12800Hz to enable the user to choose and set the exact frequency required. This is suitable for all breeds of dog for close/medium and distance work. Although very loud to the dog, this sound is not able to be heard by the human user hence the "silent" label. However the whistle is engineered to produce a relatively quiet whistle sound audible in the human range the sole purpose of this is to reassure the user that a sound in the required range is being produced. The reason for this is that if the whistle is incorrectly set up when selecting the frequency then it will not function properly without this facility the user will not realise the whistle is not working. ## Features - Whistle had Adjustable Frequency - Protective end cap - Quiet human audible sound to confirm whistle is working - However the whistle is engineered to produce a relatively quiet whistle sound audible in the human range the sole purpose of this is to reassure the user that a sound in the required range is being produced - The reason for this is that if the whistle is incorrectly set up when selecting the frequency then it will not function properly without this facility the user will not realise the whistle is not working ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000I6BMPS | | Batteries Included | No | | Best Sellers Rank | #32,921 in Pet Supplies ( See Top 100 in Pet Supplies ) #14 in Dog Whistles | | Breed Recommendation | All | | Care instructions | Hand Washable | | Closure | button | | Color | grey | | Customer Reviews | 3.8 3.8 out of 5 stars (3,729) | | Date First Available | 4 August 2012 | | Item Weight | 36 g | | Item model number | 535 | | Number of Items | 1 | | Pet Life Stage | Adult | | Pet Type | Dogs | | Product Dimensions | 8 x 1.5 x 0.99 cm; 36 g | | Quantity | 1 | | Size | adjustable | | Special Features | Behavioural Control, Heavy Duty, Lightweight, Portable | | Specific Uses | Behavior | | Voltage | 12 Volts | | batteries required | No | ## Product Details - **Brand:** ACME - **Breed recommendation:** All - **Pet toy type:** Exercise Toy - **Recommended uses for product:** Training - **Theme:** Animals ## Images ![Acme Silent Dog Whistle, 535_Silver - Image 1](https://m.media-amazon.com/images/I/61AvW5qADFL.jpg) ![Acme Silent Dog Whistle, 535_Silver - Image 2](https://m.media-amazon.com/images/I/51pS+2vGF9L.jpg) ![Acme Silent Dog Whistle, 535_Silver - Image 3](https://m.media-amazon.com/images/I/51kP-Ro4T-L.jpg) ![Acme Silent Dog Whistle, 535_Silver - Image 4](https://m.media-amazon.com/images/I/61rmEgedJxL.jpg) ![Acme Silent Dog Whistle, 535_Silver - Image 5](https://m.media-amazon.com/images/I/41HGrc+ZThL.jpg) ## Available Options This product comes in different **Color** options. ## Frequently Bought Together - ACME original 'silent' dog training whistle no. 535.
