If you don't already have a GPS unit yet, or have just bought one and want to know everything about it, you'll want this book. It's tough to find books about GPS, this one is the easiest as it's found in many large chain bookstores, and it's the most up to date book on the topic.

As his book was written for those who will use it for survival on mountaineering expeditions, author Lawrence Latham is very thorough in his approach to GPS. He starts out by explaining the GPS system, moves on to the basics of all handheld units, then procedes to give readers a thorough understanding of how to use them to mark trails, find specific locations, and how to coordinate your GPS with paper maps (a most valuable chapter!)

Rounding it all out is a section on GPS units and computers, showing the reader how to pull all of the GPS data into a PC for later reference and use, as well as how to plan an expedition with these two tools together.

The reader should note all of Lethams' warnings, as he outlnes the technologies limitations, to not totally depend upon GPS for survival .

All in all, you'll be hard pressed to find a better book on the topic.

OK, now that you've bought yourself a GPS, you probably think you are now ready to head for the wilderness, safe in the knowledge that you will know where you are....wrong! Increasingly, authorities are concerned that novice trekkers are getting lost because they are neglecting to learn valuable mapping skills that could save their lives.
