Cocktail Hour, a webcomic

Scott & Ron (now of Alpha Ghost Team) give a very thorough presentation about the basics of paranormal investigation and the tools used therein. I admit, though, when they first brought out the Geiger counter my first thought was of the Ghostbusters ghost trap, lol. There are a lot of other cool tools that can be used to hunt ghosts but these were the major ones they had for us to try out.
