You’re the first person I’ve seen to explain this clearly in a way that doesn’t leave out little details that matter. Others may be correct but yours is correct, clear, easy to remember (“I move my compass housing to the right…”Thanks.
LARS. When looking at the declination diagram notice that west is on the left and east is on the right. LARS is an acronym for LEFT ADD RIGHT SUBTRACT.
If you don't have Google in the forest, you can search for something in reality and on the map that runs in a south-north direction. Place the compass in that direction, and read the declination on the compass needle. If you want to be more precise, you look for something that goes in the direction of the meridians. However, the difference between true north and grid north is small and constant.
Simple math says if you are off by 13° on your bearing, you will deviate approximately 22.4 meters from your intended path for every 100 meters of travel. I would say that is significant and important. Also the declination on your map is based on the year it is printed. If your map is few years old you will need to do some math to adjust for today.
@@crimsoncrater6730 You've got it reversed. Since easterly 'differences' are more clockwise on the degree scale, a subtraction takes place to go back to the reference, i.e. geographic North.
She is saying that with the dial style for and easterly declination, you turn your dial(from the top) east, (counterclockwise) so the tick at the top outside the dial lines up with 347. Degrees.
I think the more confusing info here is that Colorado is at a 7-degree declination, and though I know next to nothing about declination, I don't think it shifts 6 whole degrees in just a year :)
Kay is that considered west declanation, i guess i thought the. declanation error was to west so you compensate by making your. bearing more east. Nevermind i guess i though CO was west. DOnt buy the fox conpass, it doesnt have very positivly ingaging click on the dial and doesnt have a prescise indicator mark. Or any declanation gauge.
Questions/2 of them. #1-You have an old map and since declination changes yearly, how do you set your compass declination using that Map. #2-If you don't have a map, AND are say are hiking, how do you set declination to make sure your compass is set CORRECTLY for the area your in so you can get back to your starting point.
If you track the shadow of an object around midday...with an hour in between or so....and triangulate where that shadow is pointing, that will lead to true north. That is the old fashioned super analog way. You can compare where the shadow is pointing vs your compass to calculate the declination.
Gaah! I've watched 3 videos and I still can't actually do it on my compass, which looks just like yours. What does it mean to move the north number?! I'll keep watching videos...
The top of your compass has a bezel dial. It's the ring that goes around the needle housing. You turn that so the black fixed arrow on the baseplate (the direct of travel arrow) lines up with the degress number you want. So in her example you would turn the dial so that the 347 is lined up with that arrow. Then you turn your entire compass until the needle is lined up with the arrow that in under the needle that looks like a house. We teach Scouts BSA this by saying put "red in the shed".

What if your map doesn't have the declination, or is an old map and since declination changes yearly, and you don't have your phone to Google it,what do you do.
I have topo maps from the 1940s & they all have it; that is, quality USGS-based survey maps. Ensure that's what you're using, and not a 'tourist' or general recreation-type. For the annual changes, the year-to-year differences are not that much, in my experience, for where I travel (East coast USA). So for me to use a 5 or 10 year-old document, it has not given any issues. Obviously, before you borrow or purchase a map, check that it meets your requirements before any trip/route planning. Safe travels.
yes very easy. nobody just never say where to know this Magnetic declination is it read on maps. should be LOL. and when try me good and do it. sure you turn it wrong way and you miles away LOL even you have map you see all land marks still trust compass. why we need compass? LOL LOL

or, east is least (subtract) west is best (add)
awesome thanx

So even though 13 was a positive number, she subtracted to get 347?
(360-13=347 degrees)?
Yes, it’s the difference between east and west, if it’s 13east then add, 13 west, subtract
@@crimsoncrater6730but for her it was east and she subtracted
