High EMF readings can cause a lot of symptoms in sensitive people that can mimic some paranormal elements people claim to feel in “haunted” locales. Investigators generally do a baseline reading of their location so they know whether the EMF reading is within normal limits, or if something is giving off high EMF readings that could cause someone to have a reaction.
Once they do that, though, an EMF reader can detect whether there is an energetic anomaly that shows up during an investigation that wasn’t there during the baseline reading.
As spirits are thought to be electrical/energetic in nature, you can use the EMF as a communication tool, asking a spirit to make the lights/numbers go up or down for certain answers, or to show that they are there.
We use both a manual and a digital EMF Reader. While the lights make communication easier, the digital provides specific readings so it’s easier to see minute changes in the environment. Both have their uses, so you can choose which you’re more comfortable with or utilize both, like we do.
