Using structural vibration technology GhoSt Augustine uses this device to detect vibrations in an object or surface without any apparent motion. This item is awesome for paranormal investigations. Just set one or several in a room on the furniture or floor that you want to patrol for movements. A high pitch sounding alarm will go off when any movement is made that causes the slightest vibration. *This device is VERY loud*
· Works in any position and even has a magnet on the back.
This is a fantastic way to monitor a room on the other side of the house and it is almost like investigating two rooms at the same time.
