Description

It tells you all you need to know about using hand held Global Positioning System receivers for accurate navigation in the outdoors -- how GPS works, features of all common receivers, and practical examples of use in the outdoors. Clear language and illustrations demystify GPS for every user. The well known latitude / longitude grid is explained and its use demonstrated with a GPS receiver.
