EMF Meters are an important piece of hunter equipment that measures EMFs (electromagnetic fields), commonly given off by spirits. This helps hunters find if the room is haunted, or sometimes where the spirit's body is. Although, if there are nearby power lines, the EMF meter is rendered useless and its readings unreliable. When EMF gets high, it makes noise. TBA. The EMF Meters first appeared in Phantom Traveler when Dean made his own out of an old tape player. That creation was never seen again
