The GPS/Topo Grid Guide is a waterproof field guide that explains topographical map symbols, abbreviations and the UTM (Universal Transverse Mercator) coordinate system. It's ideal for hikers and hunters who use topo maps in the field. The Grid Guide features 9 pages of topo symbols and definitions to help you read any topo map, along with complete instructions for using the UTM system to accurately measure positions on a map or with your GPS. The guide also includes grid overlays for all common map scales, including 1:24,000, 1:25,000, 1:50,000, 1:62,500, 1:63,360, 1:100,000 and 1:250,000. These scales let you quickly create waypoints for your GPS in the field, or transpose GPS coordinates to the map you are using. This pocket-sized guide measures just 3.25 W x 5.25 H, and is printed in the USA on tear-resistant, waterproof paper for field use.
