The art of mental detecting

A lot will depend on which type of detecting you plan on doing as to what book will have the most interest to you. Park/school, ghost towns, beach, nuggets, relics, etc.
I keep hearing about Von Mueller's books but they sell for $40 bucks! Is the information worth the month though?
Urban Treasure Hunter was the first book I read and one of the best.
Dr Tones has a book out and it's not too bad has some more modern information but no eye opening info to me.
I've thought about writing a book but focusing solely on modern research methods.
I have a thread in the general discussion forum titled "your favorite treasure books post em" a lot of people have posted there favorites there. Hope that helps.
I recently read metal detecting by mark Smith. It was pretty good. He through in some of his past experiences as well. Along with tips, techniques etc...
