Used to take distance measurements from point ―A‖ to point ―B‖ on maps; in conjunction with the distance bar scales on the map. NOTE. When used on a 1:50,000 map, each tick mark on the edge represents 100 meters (107 yards) of ground distance. ZERO.
To determine the exact distance to the nearest 10 meters, place a tick mark (c) on the edge of the paper at the end of the extension scale. You know that from point (b) to point (c) is 6,000 meters. With the tick mark (c) placed on the edge of the paper at the end of the extension scale, slide the paper to the right.
