Equipment & uses

This is a guide to the various types of equipment we use, how they work, and why we use them.

EMF Meters - These are not Ghost Detectors. They are just tools for detecting electromagnetic fields (EMFs). It's up to the researcher to decide the implications. Some researchers believe that consciousness is some kind of energy that can be detected using these meters, either directly or indirectly. However, we don't know what consciousness is and until we do we don't know if these meters even work at all for detecting a ghost.

Some people think consciousness could be an electromagnetic field, but if that's what it is standard EMF meters are only designed to detect the kind of EMFs that technology produces. They can't detect the kind of EMFs that a person gives off, so they shouldn't be able to detect a ghost either. However, it's been hypothesized that what the ghost hunter may actually be detecting is a reaction between the ghost's EMF and the EMFs in the environment, not the raw EMF of the ghost itself. The Trifield Natural Meter, however, CAN detect the kind of EMFs that our bodies give off, but for that same reason you can't walk around with it. You have to set it down and sit a few feet away. You can also set up a video camera to watch it and go do something else (since it's the only meter for under $2,000 that blocks out man-made AC fields, the camera won't interfere).

Some other researchers believe that consciousness is some new kind of energy we haven't discovered yet, and it's possible that it either gives off electromagnetic "radiation" or has a reaction to the EM field of the environment. However, without other data to support it there's really no way to know if an EMF spike is coming from a ghost or the environment.

A certain type of electromagnetic field can cause hallucinations or it can cause one to hear things or to sense an invisible presence.

The first thing we do is walk through and get a base reading of every room, then during the investigation if the meter spikes above the base reading we look for where it's coming from. We try to eliminate all the possibilities, and if we can't find the source we make a note of it. With experience, you'll get better at tracking down the source of the spike. When we're doing the walk through we're also looking for bad wiring or anything else that could make the kind of EMF that could cause hallucinations.

The best meters to use are probably one of the Trifield Meters, as they are the most sensitive meters you can buy. However, even the most sensitive meter on the market today is still very primitive. These meters are good because electromagnetic fields are 3-dimensional, and these are the only meters with an x, y, and z axis so you can detect all three dimensions. Otherwise, you might miss something. There are two kinds: the Trifield Standard Meter and the Trifield Natural. You can walk around with the Trifield Standard Meter, but it can't detect the EMFs that our bodies give off like the Trifield Natural can, and it doesn't block man-made AC fields like power lines.

 Temperature Readers - Sometimes on paranormal investigations we will experience hot or cold spots. One theory to explain these is the Peltier Effect. When an electric current passes between two dissimilar conductors, heat is either released or absorbed, depending on the direction of the current. If ghosts, and consciousness, are some kind of energy, then hot and cold spots could just be a natural reaction to the ghost's energy. Or, it could just be something in the environment. Once again, when we detect a hot or cold spot we just try to find where it's coming from, and if we can't we don't jump to any conclusions. We just make a note of it.

 Digital Voice Recorders - We use these for recording Electronic Voice Phenomena (EVP). In theory, EVP are ghost voices caught on tape. You don't hear anything when you're recording, but then when you play back your recording you do. Some EVP could just be bleeds from CB radios, wishful hearing, or whispers from living people. If you're using a cassette recorder without an external microphone, you will record the sounds the gears make inside your recorder. Also, never rerecord over a used tape as voices can bleed through. When we are recording for EVP using digital voice recorders, we will start by having everyone identify themselves into the recorder so we know their voices. We talk at normal volume and don't whisper. If we hear any sounds while recording (a stomach growl, a plane flying overhead), we immediately say "that was a stomach" into the recorder so someone doesn't later misidentify it as something else. We also have a video camera taping us so if we still can't identify a sound we can refer to the video to see what it is. EVP could also be our own subconscious thoughts projected onto the voice recorder.

 Cameras - It is important to keep your camera lens clean. A dirty lens can make it look like there are "orbs" everywhere. Be mindful of your camera strap, fingers, hair, or anything else getting in front of the picture. These can look like anomalies when illuminated by the camera flash. If it's cold out, you might see your breath in the picture and mistake it for a mist, so hold your breath while taking a photo. Don't smoke while taking pictures or light candles. Don't take pictures in rain, snow, fog, or sleet. Hold your camera steady. You should read through your camera's manual so you know when you're doing something wrong, and you can become familiar with all the different kinds of camera defects. Double exposure is a technique in which a piece of film is exposed twice, to two different images. The resulting photographic image shows the second image superimposed over the first. It can explain people or objects in a scene that were not originally there. If your camera is set to a longer exposure time and you aren't holding it still while taking a photo, the  picture will look blurry and there will be streaks across it. If you set it on a tripod and someone walks quickly past with no flash and a longer exposure time, the result will be a semi-transparent image that looks like a ghost. If they're wearing black, they will look like a shadow person. They can appear to be missing an arm or a leg, because they're moving so fast. Lens flares look like "orbs". Light refractions can be a streak across the picture.

 Camcorders - We use these for recording us during EVP circles and for monitoring rooms for activity when we aren't there. We will often do a control experiment where we will set an object down like a penney and come back to it at the end and see if it moved.

 Motion Sensors - We may place these by the exits so we can know nobody else is in the building, or we may put them around our equipment so we know if someone tries to tamper with our equipment. Theoretically they can also be used for detecting ghosts, but remember they're extremely sensitive and mice and bats can set them off too.

Extra Batteries - We will often experience battery drainage on paranormal investigations, so pack lots of extra batteries. Despite what you hear on a lot of ghost shows, ghosts don't actually draw energy from batteries and appliances to manifest. If that was how it worked, then wouldn't you think power plants around the world would be haunted? Actually, most researchers believe that consciousness IS some kind of energy, and battery drainage is just a reaction to the ghost's own energy. What's interesting is how sometimes on an investigation your battery will drain, and then as soon as you walk out of the site it will go back to the way it was.

Paper/Pencil - It is important to take good notes and write down everything. Before an investigation, we will do a preliminary walkthrough with our instruments and jot down base readings. Notes are also taken on vent placement, rooms where there is a lot of dust or the floor squeaks, and if neighbors can be heard outside. The day of the investigation, we will record moon phase, space weather, and weather outside. During the investigation, we will keep track of where everyone is and when, and when recording for EVP we will write down any stomach growls or planes flying overhead that someone might later misidentify as something else. We also keep on file who was all on every investigation and what equipment they were using.

Walkie Talkies - We use these to communicate with each other so if someone hears a strange sound during the investigation we can find out right away if it was one of us who made it.
