Obviously Dave has a lot of knowledge to pass on, and spent a lot of time involved in writing these books. I thank him for his dedication. But as a person who is a total lay person in bush craft, a complete beginner with no detailed knowledge of the craft, these books lack the details and deep explanations of the "how to's" of bush craft. The explanations and illustrations leave me missing a lot of information still in how to actually perform the steps to accomplish the bush craft techniques; leaving a lot of missing information so I really do not understand what Dave is trying to explain to me. You really have to have basic knowledge of bush craft already to understand his "how to" explanations, these are not beginner books. I will have to purchase other books to understand Dave's books completely.
