Without debating Newton's First Law of Energy which states energy can neither be created or destroyed, we find it intriguing that there are many methods of attempting to communicate with energies ( spirits ), who are no longer with us ( in the physical sense ).  Psychics, mediums, or anyone of us with gut feelings are open to our own interpretations of our experiences,  and so it makes sense to sincere researchers to attempt to validate these experiences.    Enter the ( expensive ) equipment.  This is a small portion of equipment that is designed to help paranormal investigators not only look for measurable proof of the paranormal, but to also aim their efforts during an investigation.
