The prime sensory instrument of any ghost investigation is an EMF meter. I feel there is more confusion and BS about the
use of these things than any other piece of equipment except perhaps a camera. The main reason why is because it can
be very hard to tell what you are reading and whether it is actually anomalous or not. After some experimentation, I feel that the Multidetector Profi (Pro Edition) is about the best you can use for the money.
Yes, it is just over a $100, but well worth it if you are the lead tech in a group. I have close-ups of both the Profi and
Standard Multidetectors above for reference. Both have adjustable settings for between E (Electric) and H (Magnetic) plus
a range switch from X1 to X1000. For quick reference 1 mG = 100 nT . The difference between the two is that the Profi has a filter function (notice the VLF and ELF settings) plus an audible
alarm and X10 more sensitivity. The VLF allegedly will screen out 60 Hz noise so prevalent in many buildings (and even outdoors).
My studies have found that it DOES make a difference, but not a total one. I often will still get readings from 60 Hz power
even with it set to VLF (500 Hz - 400 KHz ). My guess is either the filtering is not perfect, and/or power lines have harmonics
which extend beyond the 60 Hz range. For reference on the Profi, each LED light at the X100 setting represents 1 milligauss. On the standard, each LED
light at the X10 setting represents 1 milligauss. Many in the ghost hunting business feel that a reading between 2-8 mG could
indicate the presence of something supernatural. My personal opinion is that any UNEXPLAINABLE reading could be an alert to paranormal activity. What you are looking for
is: 1) A reading as above (could be 2, might be 20 mG) that cannot be explained by a local power source. For instance, if I
was walking on an allegedly haunted battlefield far from any power lines and my EMF meter started reading 1, or even 15 mG,
I would be very inclined to think something was up. But check the Solar activity for the day before you jump to conclusions.
Be sure and practice with a meter in your own home so you become familiar with what will cause an indication. 2) A reading which changes or fluctuates for no accountable reason. Standing in a room, the reading is 2 mG, then it spikes
to 9, and back down to 2. Could be something there... 3) Normal background readings which DROP for no explainable cause can be the indication that something is sucking up energy
to manifest. 4) To always try correlating the reading with some other phenomena. A cold spot, orbs on film, or even a funny feeling
can lend weight to a strange EMF indication. 5) To experiment with different settings and meters. The guide table shown above is not some law written in stone; use
whatever configuration gives you best results. Use different brands and models of EMF meters to see what works for you. On the far right is one of my favorite toys, an EMF meter mounted on a holder. I have four of these that I deploy in an
array as a form of energy trap. Works very well in front of a camera. The calibration is for 1-10 mG. Kudos to Orion again
for the holder idea. (they are small acrylic picture frames from Office Depot for less than $2 each) Slap on a 9v battery
with electrical tape or velcro and it's ready to rock. The only problem is that the original supplier of these beauties has
run out, and you will only find them further out in the supply chain. Check on EBay and www.ghostsafari.com . Incidentally, all of the aforementioned EMF detectors are what as known as SINGLE-AXIS detectors, which simply means that
they only measure fields in one dimension. So the orientation of the sensing probe/antenna will affect the reading. The TriField
Meters are famous for being TRIPLE-AXIS meters wherein they measure in all three dimensions at once. There are supposedly
DOUBLE-AXIS meters, but I have never seen one.
