Round Military Style UTM/MGRS Tool Large Print Version Scales: 1:24,000 x 1km 1:25,000 x 1km/1:250,000 x 10km 1:50,000 x 2km/1:500,000 x 20km 1:10,000 x 500m/1:100,000 x 5km Compass Rose in Degrees (Size 4.75 in diameter) This tool is an improved version of the Graphic Training Aid 5-2-12 Coordinate Scale and Protractor used by United States and NATO military forces around the world. By using a slot on one side of the tool for access to the map, the tool can be more compact than the traditional GTA tool. The tool features several additional map scales, including 1:24,000, which is the most common topographic map scale found within the United States. The 1:100,000 scale now spans 5km grid lines, making it much more usable.The overall dimensions of the tool have been reduced so that it is the size of a music CD, easily fitting into a pocket or any slot where you could store a CD. This tool has larger print numbers on both the compass rose and the coordinate scales. The inner protractor is marked in degrees. Bands of white ink are printed under the compass rose to make reading the compass rose easier and to keep the tool from disappearing when you place it on the map. Our coordinate scales offer significant benefits over the standard issue GTA 5-2-12 The tool is printed on 30 mil plastic stock with a protective coating. It is the thickness and stiffness of a credit card. Its 33% thicker than the standard issue version, so its less likely to bent or broken when you need to use it. See photo of the tool. Rounded corners keep it from wearing holes in your pockets. Includes 1:24,000 scale for USGS 7.5 minute topographic maps. Larger 1:50,000 and 1:100,000 scale rulers for maps with wider grid spacing. Larger print type on both the scales and compass rose. Internal cutouts are shown with red in the product images. The map image in the background is so that any white ink is visible. Neither the red outlines nor the map image are printed on the tool.
