The Land Sectioning Tool for 1:24,000 scale maps features a square mile section divided into 10 acre squares. Each 10 acre square has holes at the corners to allow you to mark out smaller sections of land within the section lines printed on the map. The tool also includes cutouts for drawing squares that are 40, 10, or 2.5 acres in size. There is a handy section number reference diagram. Along the edges of the tool are rulers marked in tenths of miles and feet.
