An easy to use grid tool that divides 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 tool also has a compass rose protractor along the outside edge. This makes plotting or measuring a bearing a snap. The small size of the tool allows you to keep it 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.
