![]() You lose the mills scale for artillery calls for fire and still have to draw extended lines on your map, cluttering and obscuring important details. Often hand trimming of the mils edge results in a sloppy, uneven edge cutting off degree marks. When measuring a grid angle from point A to point B on a map with the Army protractor, you are often forced to draw and extended line so you can reach the square's edge for a measurement! An improvement somewhat is to trim the mils scale off, but not a significant enough improvement. The RM protractor is round with degrees and mils scales on the outside edge. Army protractor (GTA 5-2-12) is a square shaped piece of clear plastic with mils scale and degrees on the outside edge of the square. Army SNCO, Rudy Madayag and offered in military clothing sales stores (MCSS) is far superior, easier to use and more accurate. The round and improved square map protractors produced by retired U.S. Here is information on using the Military Grid Reference System (MGRS).The current square issue map protractor ( GTA 5-2-12 ) is cumbersome to use, resulting in added time in planning, and inherently inaccurate resulting in map errors that can cause units to get lost and rounds to fall on friendly forces. Here is information on using the United States National Grid (USNG). Here is information on using the Universal Transverse Mercator coordinates (UTM). ![]() Here is a tutorial on using this type of tool. Using a slot style tool to plot/measure a 10m MGRS position Part Id: GTA, Made in United States, UPC: 824249150032 Part Id: RoundGTAQuads, Made in United States, UPC: 824249150490Ĭoordinate Scale and Protractor - GTA 5-2-12 Large Print, Compass Rose in 90 Degree Quadrants Round Military Coordinate Scale and Protractor Part Id: SuperGTA, Made in United States, UPC: 824249150063 Improved Military Style UTM/MGRS Coordinate Scale Part Id: UTMSlot-TA, Made in United States, UPC: 824249000764 Part Id: GridsSheet, Made in United States, UPC: 824249000849 Locating Coordinate Grid Information on USGS Maps It's the size of a music CD, so it tucks away in more storage spaces.ĭavid Canterbury, with the Pathfinder School, has a good video on how to make a Sun Compass, using our Round GTA tool.Larger print type on both the scales and compass rose.Larger 1:50,000 and 1:100,000 scale rulers for maps with wider grid spacing.Includes 1:24,000 scale for USGS 7.5 minute topographic maps.Rounded corners keep it from wearing holes in your pockets.It’s 33% thicker than the standard military issue version, so it’s less likely to bent or broken when you need to use it. This makes it about the thickness and stiffness of a credit card. The tool is printed on plastic stock with a protective coating.Our coordinate scales offer significant benefits over the standard issue GTA 5-2-12: This makes reading the compass rose easier and also keeps the tool from "disappearing" when you place it on the map. The inner protractor is marked in degrees.īands of white ink are printed under the compass rose. This tool has larger print numbers on both the compass rose and the coordinate scales. Plus, 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. The 1:100,000 scale now spans 5km grid lines, making it much more usable. The tool features several additional map scales, including 1:24,000, which is the most common topographic map scale found within the United States. ![]() 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. 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. Neither the red lines, colored background, nor map image are printed on the actual tool. ![]() Note: Product edges and interior cutouts are shown with a thin red line. ![]()
