CYA Military Coordinate Scale Protractor

A pocket sized set of 3 UTM corner rulers for 1:24,000, 1:25,000, and 1:50,000 scale maps. The 1:24,000 and 1:25,000 corners allow you to divide a 1km map grid to a 10m precision. The 1:50,000 corner allows you to divide a 1km map grid to a 20m precision. The tool has a hole at the corner of each scale to allow for placing a mark on the map. There is also a hole in the center that allows a string to extend the compass rose. There is a lanyard hole in the upper left corner.
The tool has a band of white ink around the edge of the tool. This makes reading the compass rose and grid numbers easier and also keeps the tool from “disappearing” when you place it on the map.
