- Every topographical map has a declination diagram to display the difference between Grid North and Magnetic North - but they all don't tell you how to adjust for it.
In this video, we'll look at the GM angle, and discuss how a simply trick can be applied to always know the difference. LARS is an acronym that many of us use and you can too!

Been through multiple schools in the Army as an officer in the reserves. Best explanation of declination I’ve ever heard and will use this to explain it to enlisted and new officers! Thank you!
Awesome to hear - keep grinding!!
I think the Army likes over complicating things at times…
Thanks Top! I was 13F for 9 years. This was my bread and butter but after being out for 10 years I didn’t use it, and lost it. watching you made the muscle memory kick back into gear. Now I’m ready to get back into my endurance races and not look like a J.A. Little bit of SGT’s Time always helps. Take care brother
Hell yeah! Right on amigo!!
Was it a fun job? Ive been kinda looking at 13F. Still in highschool, about to be a senior but I want to join when I graduate. Still not sure what I want to do. I really want to be something in 11 series but just not sure.
Great explanation of how to adjust for declination. Thank you!
Thank you for this video! I’ve spent days navigating around mountains with a topo map and compass, but that was a decade ago and I couldn’t for the life of me wrap my head around LARS again until your video. Watched about 5 others and you explained it best.
I knew if I searched long enough I would find you. No more unnecessary words coming out of their mouths falling into our ears. LARS is my new best friend thanks to you StokerMatic. 5:15
Plenty more on the channel! Glad the content is helpful.
Just a regular civilian looking to understand all of this. Thank you for the simple step by step explanation. Also thank you for your service
🇺🇸🥃
thank you for your teaching i sm from philippines always waching you sir
Great video, thanks man.
Amen. left add, right subtract. ta dah....
I know this video is a year old but this is awesome, I was taught General to Major etc during OSUT and EIB, this changed everything. Thanks!
This was by far the best explanation of using the LARS concept
Always dig this gooder land nav stuff Top. Thanks.
Right on Joe! 🥃 🇺🇸 👊
The exact video I needed to see thanks Stoker.
Great job on this for folks out there
Great explanation of magnetic explanation. Your examples and easy to follow directions simplified an aspect of land navigation that has always given me trouble.
Glad it helped!
LARS is awesome!! Thank you, this helps clarify so much!
Glad it helped!!
Very nice, easy to understand. Thanks
Best discussion of declination I've ever seen!
I’ll take that!
I second that!
Tell me your a hollywood Marine without telling me...." GeNeRAl tO MaJoR " Great work brother!
Right!?!
Doggone it, Top. That made all the sense. You're super stinkin smart for an NCO.
Just watched your amazon compass review and came here for declination explanation for the umpteenth time and it clicked. Thank you.
Glad the content has been helpful!
You picked 8 degrees as you example for the east, I happen to live right on the 8 degree line. Thanks for the great explanation.
Wow-way cool!
You broke it down Barney style 👍🏽
As always, freakin awesome....If only my sargent had this way of explaining back in the days it would have been easyer to pass land nav.
Perfect!
LARS... Good acronym thanks!
Similar stuff to nautical navigation though you have another factor to add or subtract. We had to take into account compass deviation along with variation when plotting courses. It seemed really complicated when you first started learning it but once you had done it enough it became second nature. And of course we also had acronyms to help us remember the sequence and whether you added or subtracted the deviation and variation to get your final bearing and plot it on the chart. Essential skills that are unfortunately being eroded by electronics.
Good stuff John - thanks for sharing that!
Thanks again. Can I ask you to
devote one program to differences in navigating in the southern hemisphere. Not many
guys remember us down here.
We also use 1: 50 000 maps the
most. South Africa
Thanks again
Oh right on! Will do what I can.
For use educated! Love the vids❤️💪
Awesome!
Thank you so much for this one Stoker. I was really struggling with which way to go and when, but the arrows you drew on the declination diagrams nailed the LARS principle for me. Thank you so much mate
Glad it helped!!
Thank god for your wisdom
I always stress to the future Lts over here that you can do all your planning on a map you want but once you make that jump to a compass or vice versa you have to convert. 7 years in the Corps and I only started to understand declination fully about a year ago! Tough stuff to teach.
It can be! And man up here our declination is near 20 degrees! Whew!
So if I had a declination of negative 6 west. I would need to add 6 degrees by turn my declination to the right???
Thank you!!! You helped my dumb ass to make sense of it
The easiest way for me to remember is that if the magnetic north is east or right of the grid north, then I will turn the bezel to the right (clockwise) and if the magnetic north is west or to the left, I will turn the bezel to the left (counterclockwise). That is if I'm going from grid to magnetic north. The opposite will be done if I was converting from magnetic north to grid north.
Your my oracle.
In a grid down scenario where all hell breaks loose and you are forced to "bug-out" it will be ESSENTIAL to have the ability to shoot an azimuth or reverse azimuth... when you can get "True North" to some degree you'll have the ability to know what is North South East & West in an area where visibility is 0 or in a place you are very very familiar with...
Interesting Stokerman. Recently bought a Silva ranger model base plate compass to fiddle with. Iam assuming this is how to use magnetic field to correlate with a Grid layout (map)? Where East meets West on a map layout, would that be considered "0° deg declination? What I've learned with using a Thomas guide back in the FedEx delivery days, the best way to get around accurately was to learn where "Ground zero" was in a particular City. This is where the Streets and Avenues meet with addresses starting at their lowest digits. For instance in the City of Upland, Ca ground zero would be Arrow Hwy and Euclid ave This is where North, South,East and West all meet (the center of an X) and all addresses start at single digits.
Kinda off subject. My Uncle Laslo back in the olden days, took his WW2 surplus merchant marine vessel and sailed from Louisiana to South America solely by himself using only a surplus Sextant looking for a said "Sunken Spanish Galleon" ...lol. True story, smart guy, a little nutty though.🤔🇺🇸✌️
What an interesting story! Crazy!!
Where there is no declination is called the agonic line. You could say that’s where east meets west.
Awsome
🇺🇸 👊
I one-hundo, abso-stinking-lutely approve this video. Fun fact, the north geomagnetic pole is actually a magnetic south pole, which attracts the magnetic north pole in your compass needle.
Right on Jamie! And I always found that interesting about the poles!
This is the way i remember it (tell me if this makes sense to only me brother) When going from map to ground, say to yourself "east least or west best"- in other words subtract east declination or add west declination. If shooting an azimuth and converting to grid (like when finding your position on a map) do the opposite. Instead of subtracting easterly declination you add it to your azimuth - instead of adding westerly declination you subtract it from the azimuth you shot to say a mountain top and then use your protractor to mark your map. So from map to ground its "east least west best". From ground to map you just do the opposite.
I meant to add that your vids are the best land nav vids on RUclips..thank you for the great content brother.
Right on brother! And thanks!!
@@STOKERMATIC after all this covid-19 stuff slows down you ever thought about having a meet up for subscribers? Kind of a field craft weekend or something along those lines.
True
When would you use grid as opposed to magnetic?
If the declination is less than 5 degrees, and destination is under 1 kilo away, I’ll just use grid.
So if you shoot a azimuth with your protractor and let’s say you get 49 degrees for the grid do you convert that to magnetic and follow the conversion?
You got it!
Great video, made my kid (2008-2012 Ft.Drum 11b ) watch it, then asked if he was taught LARS. He said no.I asked him a few times if he remembered using LARS again. Then he said "it's written on the map on how to convert anyway" ,I asked him a few more times if he remembered using LARS. ..... I was pissed with his flippant answer about such a critical part of a problem/solution. My Question: does the army actively teach the concept of LARS to all recruites when teaching declination? I'm wondering if he just misplaced that information in his head somewhere , 🤔
Unfortunately- no, it’s not actively taught. That’s one of the reasons why I began making videos years ago, was to teach and demo for my own Soldiers.
@@STOKERMATIC you should present your video to the land nav. supervisors and rewrite the the training manual incorporating the LARS system. ( the way that you articulated ....... It's the best explanation I have found ANYWHERE on the net.)
I have seen where people place their compass in the bottom left corner of their map when orienting map to terrain. So I am assuming that far left side line of the map is pointing to true north. If that is correct and I use the grid north lines....wouldn't that throw me off course? Do I need to consider the angle between grid north and true north?
all grid lines point to grid north. true north doesn't matter when using map and compass. if you want the "best" orientation of a map - place compass down on the declination diagram and use the magnetic north to line up with your compass.
I used my compass to demonstrate the LARS concept and now everything clicks. Thanks for clearing away the fog.
Hey stoker. I was given a map that has a “-7” as the degree for an east coast gm angle. I'm not sure how to handle this. Any analysis on what they mean by that. Thanks in advance
East coast: grid to magnetic subtract 7. From magnetic to grid add 7.
@@STOKERMATIC ah, makes sense. I've never Seen it with the subtraction sign already there. Thank you
If you're using a baseplate compass with adjustable declination, and you have the declination set correctly for your map and area, must you still account for LARS? I'd guess not but I am not sure. Thanks.
After you’ve set the compass for the declination every azimuth will be a grid one. Both on the map and the compass.
You would only use LARS for a compass you can’t preset.
Hope that helps.
@@STOKERMATIC Awesome. Thank you Stoker!
I was attempting to find out about the shifting magnetic north after watching, so I found some coordinates over the past 20 years and punched them into my maps app...crazy things happened...app crashed, coordinates could not be found, coordinates could not be seen...getting the map to look like a globe helped, still was difficult wrestling with keeping the points visible on the map. Long story short, the question I wanted to see: has the shifting magnetic north affected the agonic line?
Changed slightly, but nothing drastic the last time I checked.
How to get a map using Google maps anywhere world where can't get a paper map
Thank you for that west coast to the right man to say go to the right here on the west coast is a fight starter. Joke just don’t say it out loud
Sorry, I don’t understand still, why add why subtract
Santa lives in the North Pole (true/grid north). Your compass points to the magnetic pole.
Two different places and depending on where you are, the difference could be 25 degrees.
So, if you want to go to the right place, use the right degree - aka add or subtract your declination.
This is so confusing. Sorry i am as confused now as I was before the demo.
Maybe this one will help:

I've only gotten to 4m 32s and I'm screaming at the screen, stop the BS, jabber, jabber and get on with it. Too much nothing talk. Get to the substance for God's sake. I don't want to leave, because I'm hoping that you have something worthwhile to say . . . and just for a change I might learn something. I stay tuned with hope.
