More and more, people are trying to find ways to provide solid scientific proof that ghosts, spirits, and elemental beings do exist in our realm. As technology advances, so do the tools used for serious ghost hunters! While some of the technology may provide adrenaline-pumping results, that same technology can be attributed to many false
validations of supposedly haunted locations. 
 
Let's take a look, first, at what tools are currently being used in the field of paranormal investigators, and a bit of background information on why these tools are used. Then, we can take a more objective look at how and why some of these tools can be deceiving, and why, with all this technical advancement and "scientific investigations", the existence of ghosts or ghostly beings has yet to be "proven".
 
The most basic of tools include: 
 
• Pen/pencil and a notebook. This is to jot down any notes and to record details of the investigation.
• Flashlights: This one's easy. Most paranormal investigations are done in the dark.
• Cables & extension cords: why, to plug in all the high tech gadgets, of course.
• Extra batteries, cassette tapes, and film.
 
Now, let's get to the good stuff. Here's the latest craze of techy tools for the paranormal investigators, "professionals" and amateurs alike:
 
• Digital Camera: For catching strange phenomena in still shot photos
• Standard 35mm camera: to offset shortcomings with digital results
• Video/Surveillance cameras: for recording strange movements or apparitions
• Infrared cameras for recording photos/videos in the dark
• EMF Meters: For locating fluctuations in the electromagnetic fields
• Compass: the non-digital tool of choice for locating electromagnetic field fluctuations
• Audio Recorder: for recording E.V.P.s, or Electronic Voice Phenomenon, with a special microphone for filtering out background noise
• Digital audio editing software: to analyze E.V.P.s
• Thermal Scanner: a no contact thermometer for recording temperature variations.
• Motion Detectors: to be used in rooms without human observation/interaction to detect motion where people aren't present.
• Ion Particle Counter: Used in conjunction with photo/video anomalies to do determine if the anomalies have actual substance as opposed to light reflections.
 
Of course, there are always the good, old fashioned ghost-hunting tools, too:
 
• Dowsing Rods: Copper rods used for locating spiritual entities and/or portals (also used for locating water and/or energy sources).
• Pendulums: for divination purposes
 
Psychic mediums are also often employed as "tools" during paranormal investigations.
