Why use EMF meters to check electromagnetic fields?
A. Spirits are Electromagnetic in nature, and as such use and affect Electromagnetic Fields. As with the thermometers, you can take the base readings of a place first and eliminate the obvious things that would normally raise the reading on the meter. Once the parameters are set, you can watch for a spike in the areas you are searching. A spike will usually mean ghostly activity. Remember, they have gathered all that energy to be there and you will surely get a spike on the meter in their presence.
