A ghost-hunter's tech toolkit

Before you start the next great poltergeist hunt, check out our skeptical look at what ghost-hunting gadgets supposedly reveal.

EMF Meter



Ghost hunters link sudden spikes and changes in electromagnetic radiation in a given spot to a ghostly presence, so no paranormal kit is complete without an EMF detector to measure electromagnetic fields. (Hint: If you’re looking to test this out, a compass will spin in areas of high EMF.) However, household and industrial appliances generate electromagnetic fields, and obstructing these fields will cause a spike on an EMF meter. A paranormal investigator might note such a change and consider it ghostly evidence, when in reality they’re just walking between two fields from other equipment.
