Koolatron Pro Series Ultrasonic Bark Control Training Aid with A/C Adapter, Black

The Pro Series Super Bark Free Ultrasonic Training Device is an innovative and advanced dog training device designed to stop a dog's annoyance or boredom barking habits. The Pro Series Super Bark Free features a specially-designed sound selector that lets you choose ultrasonic frequencies that can only be heard by dogs, or lower sound tones audible to human ears. Both sounds have been proven effective in training dogs to stop barking The Audio Activation Sensor can detect a dog's barking up to 60 feet away from the unit, and with the sliding sensitivity control and audible sound output selector, you can customize the internal pick-up microphone to the sound of dog barking. The Pro Series Super Bark Free takes four “D”-size batteries (not included) for remote operation and can alternately use the included A/C adaptor with a 50 feet low lead cable, so you aren't dependant on just battery power. Consistency is important for effective dog training and the Pro Series Super Bark Free Ultrasonic Training Device comes equipped with a timer to target specific time of day barking situations. If the device triggers randomly, the dog may become confused and will not associate barking with the corrective tone. The timer serves to extend battery life too. This Pro Series Super Bark Free is smaller than its predecessor, making it more discreet.
