Bark Stop, Bark Free Dog Silencer & Animal Pest Repeller - Yard Sentinel Dual

The Yard Sentinel DUAL has taken years for our research and engineering department to develop. But we are finally able to announce the recent breakthrough in the industry with a new multi-functional device that combines the dog silencer with the pest & animal repeller making it the best dog silencer / pest & animal repeller in its market. Unlike any other Dog Silencers who has only either ONE silencing, or ONE sensor and NO pest repelling technology; the Yard Sentinel DUAL offers BOTH silencing and repelling technologies, with Higher adjustable Ultrasonic Frequencies and louder, faster adjustable Intruder Alarm; the Yard Sentinel has successfully made both technologies very effective against silencing dogs and at the same time repelling pests, animals and intruders. On top of that, the new switchable Dog Bark Scanner which has a higher sensitivity / accuracy than most other dog sensors, and the most technically complex Infrared Motion Sensor that is only available in Yard Sentinel DUAL, is fully able to satisfy your need and maximize the full effective range making Yard Sentinel DUAL the obvious better choice to live a bark free and pest free life.
