If you've received a GPS unit, for Christmas, birthday, whatever, and you've been wondering what you can do with it, this book is for you.
The book is written by the people who run www.geocaching.com and it is to say the least, complete. It covers what geocaching is (sport, hobby, excuse to go outdoors and play with electronics), what you need to have, what you need to bring, and techniques for geocaching.
As far as I am concerned, this book should be required reading for anybody who wants to go outdoors and have fun. Geocaching is sort of a treasure hunt, orienteering, hike in the woods thing. The book takes you through the whole thing.
The section on how to use a compass along with your GPSr is worth the price of the book by itself.
I highly recommend the book.
If you go on the website, or come across a cache I've visited, just look for Scott9282, fearless leader of Team9282.
I'll be waiting.
Bring the book.
