Below is a brief list of equipment we commonly use in investigations, Although education is the best way of equipping yourself in this field, many devices aid our cause,THIS IS IMPORTANT TO NOTE 1:  None of this equipment was designed specificly for paranormal research, each individual item is used because of its particular merits towards documenting possible enviromental changes caused when paranormal phenomena occur 2: This equipment is only used in the collection of data and possible evidence. It is only through later analysis of this data that we can correlate  and present it as strong objective evidence to the existence of paranormal phenomena. Many claim absolute proof of ghosts from emf fluctuations, tempreture change, pressure drops, these are only indicators
environmental changes, as we do not know what constitutes a ghost/spirit, or even more importantly that ghosts are infact the spirits of the deceased. We cannot say this is the definite  cause of those changes, only that when certain preternatural phenomena are experienced these changes are often present.               A VERY IMPORTANT OFTEN OVERLOOKED FACT, we know the paranormal exists (in a broad sense of the word, in this context hitherto unexplained natural occurrences not just the "ghost" phenomena) but as at this point in time we have no way of  empirically measuring the force or energies behind the phenomena, just the effect it has on its surroundings. How do we know the paranormal exists? Well some of the strongest evidence we can collect is EVP although widely accepted as a objective phenomena, It is still beyond the explanation of science and human understanding and that is the dictionary definition of paranormal. The list of devices we use is ever expanding and not all of our kit is shown.
