What a better way to do an evp session You can use one K2 for yes answers and use the other for the spirit to reply with no It is fantastic to use this meter while doing an evp session to see if you get responses with with the K2 and an audible response at the same time Electromagnetic fields or EMFs are emitted by electrical devices of all types EMFs are everywhere originating from appliances cell phones electrical wiring and even the human body The K-II EMF Meter helps measure these fields to identify appliances that produce high-level emissions allowing users to make informed decisions about limiting exposure EMF fluctuations have also been associated with locations where unexplained phenomena have been reported including alleged hauntings The K-II operates on a single 9V battery and reports EMF measurements in five milliGauss ranges Please note: this product is intended to measure electric fields and does not detect nuclear radiation
