New Bark Free Pro® has a specially designed sound selector that lets you choose ultrasonic frequencies which can only be heard by dogs, or lower sound tones audible to human ears. Both sounds have been shown effective in training dogs to stop barking.

Bark free pick-up sensitivity adjustment allows you to control how loud the bark must be to trigger the correction tone, while reducing any false triggering. Bark free is weather resistant, but not waterproof. Direct exposure to water will temporarily reduce the sensitivity of the microphone and speakers. But using a weather resistant outdoor case you can use it outdoors. The unit includes mounting slots and screws for fastening on it to a building or post.
