I came across this book after reading a review on the Skills for wild lives site.
The blurb on the back of the book says "Put away your map and look up from your GPS". Navigating without a map and compass is not really what this book is about for me. It is about appreciate more of your surroundings. There are lots of interesting practical facts and tips about navigating using the environment around you. Where does the sunrise through the year, how the stars rotate on the celestial sphere.
This is not just a manual. The information is also combined with history and folklore. Lots of research has gone into navigation techniques used by older cultures. I won't be giving up the map and compass, in fact I have still got a lot to learn but I will try and be a bit more observant. I will probably reread some of the sections but this more a comment on the reader rather than the writer.
There is a link to the book on amazon on Nicks Skills for wild lives site
