5.ELECTRO-MAGNETCI FIELD DETECTORS:
Otherwise referred to as EMF meters, these devices can add an
important element to any investigation. Their purpose is to detect
the presence of electro-magnetic fields. Such fields can be
generated by ghosts and has been related to haunting activity.
Be careful of jumping to conclusions if you do get an EMF
reading. First, you must rule out the possibility of an electrical
or magnetic source. Televisions, appliances, electrical wires
and (strangely) pipes in the walls or ground can generate
EMF's.
EMF meters can range from the relatively cheap ($20) to
somewhat expensive ($200). First decide what you want in
an EMF detector. Here are some features to consider:
1. The frequency sensitivity range can vary greatly between
models. Some can detect between 20-10,000Hz. Others may
detect only between 40-60Hz. A substantial difference wouldn't
you say?
2. The way in which a measurement is displayed can also be of
importance. Some may only have a green and red light display
allowing you to document the range in which a magnetic field is
(i.e. 2.5 to 7 milli-gauss). Others have a needle resembling the
peedometer on your car. This will give you the comfort of
documenting an exact reading. Still, others have a digital
display. Although more expensive, the digital display will
give you an exact reading to the decimal. Also, they usually
have a light feature so you can see what you are doing in the
dark.
3. An audible alarm is a helpful feature to consider. This will
inform you of an EMF detection without having to keep your
eyes on the device.
