A. Nothing. Ghost Hunters are too cool for fanny packs.
Haha. Seriously though, this is a nice summary of some basic equipment that paranormal groups use. It’s funny, when you think of it, of how ghost hunters use equipment that has a different original intention, such as an EMF meter. I doubt the person who first made the EMF meter thought to himself, while leaning back in a plush leather chair with a glass of brandy and cracking his knuckles “Ah! Finally, a tool for ghost hunting!”
