“Grid to Mag - Add. Mag to Grid - Get Rid.” Best way of remembering it, and what we were taught.

I remember seeing one video of a guy saying.... Grid = General Magnetic = Major General to Major is a demotion... Major to General is a promotion... Seems like his example is flawed

I don’t even look at the titles when Pat posts a video, I just watch that shit cause it will have life saving or life changing info in it! Thank you sir for sharing all of this stuff with us, you kick ass sir! Also, love the ninja turtle face map🤘

Even many a General cannot read them properly. Don't feel bad. 😁

Great stuff, I was a Cav Scout and our training nco SFC Bill Marshall (RIP) was involved with macv before coming to our scout platoon. You could have dropped this man anywhere and he would get back. But they would hand anyone in the squad the map at anytime and say get us out, and you better be squared away.

As long as you don't have a 2nd Lieutenant you should be good. :)

Good class on a rainy day that low pressure just won't go away.

Good info, should mention the more points of interest you have, the more accurate your position will be. Also when converting magnetic to grid north, a map may have a certain number of degrees of change per year, such as 5 degrees. If the map is made in 2018 for example, then you would subtract 5*4 = 20 degrees from the magnetic north number. And if you can't remember LARS, the UK teach "Grid to Mag, Add" and "Mag to Grid, Get Rid".

Yep. The map could be 20 year old with an annual variance.

Map orientation #1 👍🏻👊🏻 always first

Did this once in an airplane I was flying, not knowing exactly where I was. I plotted radials from 2 separate VORs (navigational beacons) to plot my position on a paper map. Worked great.

I personally think the map looks like a crazy face. 🤪

Definately has a van Gogh or a Dali vibe to it. Glad I wasn’t the only one!

Pat, I need you to coach my life! For years I have never understood Grid to mag = add, mag to grid = rid. I literally get it now after watching this video!! Dude, you are cool

Good refresher after so many years!

Learned this twenty years ago as a cadet, completely forgot most of it, and have rediscovered it. Bit of a mindf*ck at first but really satisfying when it clicks. I've been practicing resections in the Peak District, Derbyshire. Started off using churches, river-track junctions and major road bends as landmarks but plan to progress to using ridges and hills.

We used grid to mag add mag to grid get rid. Also check the date of the map

Pat Mac will keep us all alive during the apocalypse! 👌

Thanks for the additional map info. Good stuff for sure.

Resection is “Me section”. Basic Dude Stuff Good to go Chief!😀

This was the only thing I missed on EIB testing otherwise would've had True Blue... still haunts me!

Great video, Thanks again Pat!

I'm great at knowing where I'm at and what direction I'm going in my home town....

I never could figure out how to convert magnetic north to true north for years until now. BAM! Pat Mac is really good.

That map looks like Pepe the Frog. You're welcome to all who can't unsee that now.

Pat, a great refresher course from you, I had good NCOs (But bad Teachers)

If it ain't raining it ain't training RE is Me!

Thanks pat mac! next land nav course im going to try this!

I've known how to find myself on a map but not how to accurately pinpoint myself. Now I do. Thanks.

Outstanding

Awesome mac, thanks so much!

It's raining your getting old brother remember back in the day???? Take care from southern 88 degrees California.

I've learned a lot from Pat Mac. Keep it going brother. Make more video's to teach civllians how to survive everything from Vehicle Preparness to Home invasion. What to do and how to do it properly. God Bless America

Thanks Pat. I’m constantly getting lost with nothing more then a topo map & protractor

As we use to say Mag to Gid get rid, Grid to Mag add

Thats how I doodle Burglars too man.

Sadly, whatever I used to know about using topos I forgot with prolonged use of gps.

Dammit. Where’s my protractor? Lol!

Your map is watching us

Liquid sunshine brother....lol

This is like scouts for adults or PLDC for civvies. 🤘

I can remember orientation, surface features (saddle, draw etc.) some 6-digit grid coordination but not LR add subtract. Maybe too much for this 63B

Isn't the back azimuth with the 6 degrees declination for the first point 156 degrees? west is best east is least.

Two bearings technically don´t tell you anything about your exact position; You have to at least take a third one to construct a "triangle of error" you can assume you`re inside of with relative certainty. Also, it pays off to invest in a compass with adjustable declination if you´re serious about orienteering, saves some thinking.

@@angus4105 however accurate the needle points north, the margin of error when you read the bearing is right around three degrees for a mirrored compass because of possible parallax errors or the design of the needle or the scale. For mirrorless compasses it's more than that. Assuming you take bearings from objects at an equal distance with an angle of 45° between them, this error misplaces your position for ~14% of the distance. For 90° it's still 5%. You tell me if that's accurate enough.

You have a map dickhead. You use features on said map to confirm your resection. As in using your eyes to confirm features around you rather than blindly trusting a pointless third bearing. Just how far do you intend to march on one resection? It pays off to have a current map with the correct magnetic variation for that year. Not the hilarious prismatic compass you think compensates for your shit navigation skills. I have navigated in the dark just using a Silva compass in mils with tritium inserts. That is what "ranger beads" are for. Its why the mag to grid conversion is so important. Your "third bearing" is completely fucking pointless as it has the exact same margin of error as the first two.

Grid coordinates coming soon?

The map looks like a frog rolling his eyes.

Just use your GPS....😁

It doesn't always work in deep valleys or ravines found in mountain ranges. GPS is just another form of resection and needs line of sight. No signal. No GPS.

More lessons brother

Can you explain back azimuths? Is it just the opposite bearing on your compass?For instance, if I had a bearing of 90° is the back azimuth 270°?

@matthiasthulman4058

Yeah, whatever your bearing is, the back azimuth is the basically the exact opposite bearing. Edit: bearing in degrees
