Q: " Will the Super Bark Stop (ES-VT-BC16G) work through a fence?"
Answer: Not if the fence is a solid one. This is an ultrasonic sound device just like the ultrasonic rodent repellers but tuned to the frequencies that dogs here. Ultrasound behaves more like a light beam than sound that you hear. If the fence is a cyclone fence or the Barkstop is placed in the open space between the fence posts, some of the ultrasonic waves will go through to the adjoining yard.
Some customers install this unit in a birdhouse enclosure and aim it down over the fence. This will limit the area of coverage, however. Others have mounted the unit to their house or to a tree. The closer the unit or similar units are to the animal, the more effective it is. The maximum range is about 35 feet.
Please contact us if you have more questions.
