Thanks for the kind words.
I've been prospecting since the mid 1970s, and ended up getting a degree in Mine Engineering at the Mackey School of Mines - part of the University of Nevada. Yet even though I got my degree, I kept up panning, dredging and otherwise prospecting out in the field - because I enjoyed it.
What you know makes all the difference when you get out in the field, and as I was looking at the books available, I saw that most were written in the 1970s and 80s and did not include a lot of info which I thought they should.
So I spent 10 years working off and on to produce a book that had all the info I thought a book on prospecting and gold mining should offer, including all the new info on metal detecting, because the world of technology has changed since 1980.
The book has been a big success, in the 4 years since it came out, I've sold more than 6000 copies. Its available at most prospecting stores and through Amazon.
