So you want to be a ghost hunter? PARA-4 recommends any and all of the following books to help you on your way! We highly recommend "The Ghost Hunters Bible", "The Field Guide to Spirit Photography" and "The Ghost Hunters Guidebook" if you are truly serious about becoming a ghost hunter. These books contain the methods and steps needed to perform a good, solid investigation and are the books used by PARA-4 for training purposes. Don't spend $30.00 or more (in excess of $100.00 in some places) for a Ghost Hunter Certification when you can get these books and learn everything you need! These books are the reason that PARA-4 has not written an extensive training program for Ghost Hunters, there is no need!
