Why do ghost hunters use EMF meters?
First of all, EMF meters do not detect ghosts. Well, they probably don’t. Researchers who have been doing this for decades will tell you that using equipment like EMF meters is for the purpose of detecting the effects ghosts have on the environment. Since we still don’t know what ghosts are, it is the only way. We take base readings and then we compare those reading against supposed paranormally active situations and then we look for differences. Even many of the investigators on TV will tell you this. How the TV producers spin this information is usually very different. It is often easier to say EMF meters detect ghosts as opposed to explaining the science behind the technology.
