Military Round Protractor #7
The only known BACK-UP of the GPS when it malfunctions is your ability to use a military protractor and sighting compass.
The RM #7 and #21 are the only models with a printed formula and a diagram to align map grid north to match the compass magnetic north. Protractors without the conversion formula will provide a reading that is off the exact grid coordinate position.
The GPS will not penetrate sandstorms, rainstorms, snowstorms, smoke, structures, forest canopies, and thick cloud cover.
GPS readings are distorted during thunderstorms, electronic interferences and when bombing support is very close on enemy positions.
It can be jammed and detected when near or behind enemy lines. Moisture is a common malfunction of the GPS.
Don’t let yourself be caught relying solely on electronics or batteries that can fail you. Always keep your land navigation skills fresh by practicing with a map, compass and military protractor.
