@sargefaria sry 2 bother...again...but I need an explanation for a 3rd time. So if my declination value is 9E and I am looking into my compass at the terrain & get a reading of 221, do I subtract or add when I convert it into the map degrees? Would it be 221-9= 212? And is that MG--->GM? Please reply Sarge Your explanation is great but my dumb ass needs a little more icying on the cake. :) - Francisco
If you have an Easterly declination you will want to add brother (left add, right subtract). So if you are shooting the azimuth with your compass (that is magnetic north) you will add the 9degrees to the 221 to make it 230degrees on your map (map being....grid north). hope this helps my friend!
By looking at the declination diagram on your map, that is how you tell if it is easterly or westerly declination. So if yours is easterly as you say.......the vertical (straight line).....
represents grid north. The other arrow would be magnetic north and would be on the right side of the grid north line, at an angle obviously. Not sure i can explain it any clearer than that without physically showing you brother. Hope that squared ya away!
Just remember to make BIG numbers smaller and SMALL numbers bigger with the KEY (midpoint) being 180 degrees. Easy-peasy-lemon-squeezy. Airborne leads the way.
Sarge thanks for all your vids. I was watching another video about Declination. This guys was saying that if you have an Easterly Dec. to subtract ( 90 degree bearing 10 degree East Dec so subtract 90 -10 = 80 degree bearing) and if the Dec is coming from the West to add (90 + 10 = 100 degree bearing) don't know if he was right or wrong.
Thanks for doing this series! I'm trying to brush up on my nav skills after 13 years out of the military. I don't remember hearing it in the vid but a tip I was taught to remember the conversion formula for grid-magnetic/magnetic-grid is the acronym LARS (Left Add Right Subtract). Same process, just a different way to remember it. Hopefully it'll help someone. Thanks again, good work!
I don't know if this will help anyone else but, No matter how your map is oriented (GM to MN MN to GM) if Im converting from right to left I add. if from left to right I subtract.
Exactly what the little diagram is showing there buckshot. Sorry I didn't mentionn it that way tho, that might clear it up for some people. Thank you!

And with GN-MN, that's the best way to explain it, great job Sarge ;)
