Dave is a good friend, and I'd advise anyone interested in navigation to read anything and every thing he's written. I have a shelf of his books and add to them almost annually, some updates, some new books.
His new book on electronic navigation is also a very good read. I was over at his place Saturday and walked out with his classic Hawaii by Sextant. Another great one on this topic.
