Environmental energy converted to Yes and No Responses for Ghost Hunting. The EPOCH Box is not a motion sensor. The EPOCH Box reads the environment and converts the energy (similar to the Ovilus) into Yes or No responses (using a sophisticated algorithm), lighting the green light or red light. The idea is to make communication easier. Just like EVP, nothing is guaranteed to produce results. The EPOCH Box reads atmospheric electricity and the movement of charges. This includes triboelectric, EMF, charge density, RF, polarity and strength of the charges. When the condition is right the red LED will light up or the Green LED. It is not a motion sensing device, it is reading the environmental energy. Parapsychology has studied the effect of Telekinesis on electronic devices and found humans with this ability can affect electronics. The theory is that a spirit can also affect these devices. This device is quiet, it has no sound. Great to use during an EVP session. Features: Quality Black ABS plastic enclosure with blue silicon boot Uses 4 AAA batteries Easy to see lighting (Green and Red) All our devices are made-to-order and tested.
