hiking and camping

That's what the author should use as a tag line. I thought I was pretty good with a map & compass, but I learned several faster, easier techniques from this book. This text is suitable for beginners to intermediates. It includes key info for people who've been delaying their first USGS map purchase, because they've been intimidated by the "experts" at their local outdoors store. You'll be happier with your next compass purchase if read this book FIRST. The section on GPS is brief but useful as a primer for a more specialized text on that subject. One of the trickier diagrams on declination **might** be wrong but the text is correct. Overall I was very pleased with this book.
