A pocket sized tool with slot scales for 1:24,000, 1:25,000, and 1:50,000 scale maps. The 1:24,000 and 1:25,000 scales allow you to divide a 1km map grid with 10m precision. The 1:50,000 scale allows you to divide a 1km map grid with 20m precision. The tool also has a compass rose along its outside edge marked in degrees. This makes plotting or measuring a bearing a snap. The small size of this tool will allow you to keep it handy in your pocket. A band of white ink around the edge of the tool makes reading the compass rose easier and also keeps the tool from “disappearing” when you place it on the map. There is also a lanyard hole in the upper left corner.
