Emf Meters (Tri-Field, etc.) -

The EMF meter is primarily used for detecting electromagnetic
fields that are believed to be put out by apparitions and other
paranormal anomalies found in paranormal activities.

Advanced Use: It is recommended that higher grade EMF meters be
used, as they have a higher percent of canceling out man-made
sources of Electromagnetic fields. Most man-made sources of
electromagnetic fields range from 0-4 em frequency. Most of
these sources range from old wiring, unshielded wiring, gas
lines,etc. Running water and aviation equipment/ planes can
also cause disturbances in the EMF frequency, so these must all
be accounted for when trying to determining whether an area has
paranormal activity.
