There is no such book.
But, if you can find a copy of "Inside the METAL DETECTOR - First Edition", you can build an LRL and /or PDK by reading Chapters 13 and 14 ->

The book is now at Edition 2, and the LRL stuff is no longer included. Edition 1 is out of print, but you might be able to find a second-hand copy somewhere.
However ... remember: "Here there be dragons!".
