K-II meter

A K-II meter is a device used in paranormal investigations to detect potential spiritual activity by sensing electromagnetic field (EMF) fluctuations. It has multiple colored lights that illuminate when EMF levels change, which some interpret as signs of nearby spirits or energy. The device is simple to use: it’s held or placed in an environment, and the lights indicate variations that could suggest supernatural presence. While it relies on changes in electromagnetic energy, the scientific community generally considers it an unproven tool with no confirmed connection to paranormal activity.
