![]() ![]() ![]() Moisture is a common malfunction of the GPS. It can be jammed and detected when near or behind enemy lines. GPS readings are distorted during thunderstorms, electronic interferences and when bombing support is very close on enemy positions. Suitable thickness: the topographical maps tools are as thick and hard as credit cards and have a protective coating Each is 33 percents thicker than. The GPS will not penetrate sandstorms, rainstorms, snowstorms, smoke, structures, forest canopies, and thick cloud cover. Protractors without the conversion formula will provide a reading that is off the exact grid coordinate position. The RM Military Protractor is the only protractor with a printed formula and a diagram to align map grid north to match the compass magnetic north. ![]() Here is information on using the Military Grid Reference System (MGRS).The only known BACK-UP of the GPS when it malfunctions is your ability to use a military protractor and military compass. 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. ![]() Protractors without the conversion formula provide a reading that differs from the exact grid coordinate position. Neither the red lines, colored background, nor map image are printed on the actual tool. The RM Military Map Protractor is the only protractor with a printed formula and diagram to align the map grid to north to match the magnetic north of the compass. Note: Product edges and interior cutouts are shown with a thin red line. ![]()
