Ghost hunting is the practice of investigating locations that are believed to be haunted by ghosts. There are many different ways to check for ghosts, and the most effective methods will vary depending on the specific location and the type of activity that is being reported.
One of the most common ways to check for ghosts is to use electronic equipment. This can include EMF detectors, which measure electromagnetic fields, and thermal imaging cameras, which can detect changes in temperature. Ghost hunters may also use audio recorders to try to capture EVPs (electronic voice phenomena), which are disembodied voices that are believed to be from ghosts.
