This is the exact electromagnetic field meter used on the Stories in the Cemetery Interactive Ghost Hunting Experiences in downtown Charleston, SC.
This EMF meter will measure, but not differentiate between three types of magnetic fields:
Natural EMF from the earth.
EMF from electronic devices.
EMF from unexplained/paranormal sources.
Simple to use or great to use as a setup in a haunted room. Simple on/off button in the middle of device makes this an easy to read must have for your ghost hunting toolkit.
