Matter of fact yes their is some info on it, a guy named Joe Shead has a book and DVD out.
I was a little
on the idea of a book, but I tell you what it is down to earth reading, very easy, and "it works". The big thing he pushed was take your time, and be able to see everything. Worked wonders for me last year, even found small spike sheds.
Try this if you want..... take a shed outside in the yard, turn around and throw it over you head, depending on your area throw it hard. Now try and find it, funny thing for me was I thought they alway landed flat on the side, I found them sticking tines in the ground, upside down and even in a cedar tree. The fresh drop sheds are the one that make my heart beat, they still have the fresh (bloody) skin ring on them, and the base is still some what soft.
