Using innovative bark identification technology powered by micro electro-mechanical acceleration sensors, the BarkLimiter series is able to distinguish between barking and other vocalizations. Also exclusive to the BarkLimiter series is Advanced Bark Correction Technology, which delivers consistent and instantaneous correction, while virtually eliminating false corrections caused by external noises. And it all works right out of the box with a convenient Autorise setting that automatically programs the stimulation intensity level based on the barking behavior of each individual dog. Or, choose manual or vibration options for alternative modes of correction. This lightweight, compact device is the perfect training tool for any dog with nuisance barking. Bark Differentiation Technology: The BarkLimiter detects bark signals solely through vibrations from a dog’s throat. This virtually eliminates false corrections caused by scratching or scraping of surfaces, or other noises like the barks of nearby dogs (as in a kennel situation). In addition, BarkLimiter has been designed to recognize qualitative differences in barking. It corrects for obsessive or nuisance barking and ignores “good” barking. This allows the dog to communicate injury or threat without activating the device. Autorise Technology: BarkLimiter is automatically set for the Autorise function right out of the box. No additional set-up is needed. This gives the dog owner immediate relief from nuisance barking. Autorise starts at the lowest correction level and gradually adjusts it up to the level to stop unwanted barking without rising further. Manual Setting: Dog owners have the choice of switching from automatic to manual settings, if so desired. A built-in Bark Odometer helps determine the effectiveness of the manual correction level by counting the number of barks. Vibration Setting: Dog owners can set the BarkLimiter to correct barks using vibration for an alternative to stimulation. Compact, Lightweight, Waterproof: The BarkLimiter is designed for maximum function in a minimal form. With integrated stainless steel contact points optimized to work on all dog breeds and coat thicknesses, and easy to access battery compartment all housed in a compact design. Rechargeable Battery: The BarkLimiter Deluxe features slim, rechargeable lithium-ion battery offering a battery life of up to 3 months between charges.
