1:24,000 Scale "Pocket Sized" UTM Grid. These easy to use grid tools divide a 1 kilometer grid square into 100 meter squares. Align the tool on the map grid and read off the easting and northing values. The tools also have a compass rose along their outside edge. This makes plotting or measuring a bearing a snap. The small size of these tools will allow you to keep them handy in your pocket. A band of white ink around the edge makes reading the compass rose and grid numbers easier and also keeps the tool from "disappearing" when you place it on the map. In the center of each 100m square a small dot, makes it easy to read the coordinate with a 50m precision. There is a lanyard hole in the upper left corner. Printed on 30 mil plastic stock the tools are about the thickness of a credit card. The ink is coated to protect it from abrasion. Size 2.75" x 2.75" (7cm X 7cm).
