So far I haven't gone ghost hunting with it, but it is interesting to see what EM Fields you are exposed to on a daily basis.

A must have for those who suspect they are sensitive to EMF.

Hi, I use this for a tool in ghost hunting.. EMF's can be used to show paranormal activity or to prove the lack thereof by showing the electromagnetic fields being high in an area. This can cause a feeling of being watched or icky feelings.
This has been an invaluable help!!
Thanks so much!
