Petsafe Outdoor Bark Control

The Petsafe Outdoor Bark Control unit detects barks up to 15 metres away via an internal microphone. Upon detection, the unit will automatically emit an ultrasonic tone that can be heard and is irritating to dogs but is inaudible to humans. Startled by the high pitched tone, your dog will cease barking. No receiver is required for this product and can be left free standing or attached to verandas or trees. This system is perfect for deterring multiple dogs from barking or even neighbouring dogs. A 9 Volt battery is required for this unit (not included).
