Ghostology, The Art of the Ghost Hunter, Review

I found the book to be critical of many of the ghost hunting techniques.  It has a lot of good historical information about ghostology and useful technical explanations of many devices. However, I thought the book was too analytical in parts. There is a great deal of physics, meteorology,engineering and scientific mumbo jumbo. The author offers several opinions about the use of certain devices. He says that there are no devices that can detect the presense of ghosts, which I do not agree with. He pooh-poohs the use of EMF meters, thermal images of spirits and does not believe in orbs. The author seems to be more supportive of far past experiments in EVPs and early photographs of apparitions. The book says it is not a guide to ghost hunting. It is more of how not to do paranormal investigations. Overall the book provides a good deal of useful information. But just like with sightings and reports of unusual phenomena, you have to take his personal commentaries with a grain of salt.
