Magnetic north has been on the move for the last 100 years. Earths magnetic field will flip in the next 40 years.

Your instructional visual aids gives the best presentation on compass I’ve seen to date. Although your video was made 11 years ago, and I’m pretty familiar with adjusting for declination, I loved it!

Has the declination changed enough to make a difference on older maps. I know it is shifting.

Holy crap. I've watched 50 videos on this subject and remained lost. You succinctly described everything in a comprehensible way.

I have to say that I have not seen anyone explaining declination as good as you have, not to mention that lines-on-the-map "trick" awesome! Thank you.

Great content .. thank you for your hard work

Nice machine. Thank you. Great book shelf

this is it orient my map to mn and then thats it !!!

Best video yet 😎😎😎subscribed !!

Very well made...nice work

Thank you for your video. I’m trying to implement this in my backyard in Houston, Texas, attaching the top of the tarp to the 6-1/2’ wooden fence and the bottom to the two T posts. I’m having trouble sourcing the T posts with the attached tabs. Do you mind telling me where you bought yours? I can probably figure out a way to lash the bottom two corners to the stakes but in a storm and potentially in the dark, would like a hassle free installation, since I’m doing this by myself. My Great Dane doesn’t like to get her hair wet and will be indoors telepathically sending me moral support. I’m opting to use the fence for the high side so my yard guy only has 2 posts to work around. Any advice would be greatly appreciated. I’ve looked at several videos along these lines and yours far surpassed the others.

wow what a great video. I love the model you made. Thanks for sharing.

Have feeling you come from a mechanical back ground

Excellent video. Thanks! LARS - Left Add, Right Subtract. If the MN is left of True North, add the degrees. If the MN line is right, Subtract the degrees.

i bought one, great product but it keeps coming untied. Do you have a customer service number? thnks

Phenomenal - specifically as a use for someone confined to a condo or apartment, thank you very much.

As my old granny taught me "grab opportunity by the forelock 'cos he ain't got no tail"

Thanku so much! Helped a lot!

So clear amazing thank you 🙏🏻♥️

Love the link between the diagram and huge compass.

After adapting due to declination it would help if the example takes that explanation one step further and translate it to the direction of travel, explaning the differences between taken MD into account and when not. Second, maps very often have map grid on it iso GN. Maybe not in USA.

Excellent in my part of nc we get 3 to 4 inches of rain per month. This method plus rain barrels would solve mybrain capture needs.

Excellent demonstration.

Very clear and well demonstrated tutorial. Many thanks for the clear and comprehensible explanation.❤❤

I didn't read through the comments, but here is another way to remember if you need to add or subtract. Reading the Declination Dia from Left to Right, going from Grid to Magnetic or Magnetic to Grid, we read it like this Grid to Magnetic (Greater to Minor = Subtract); Magnetic to Grid (Minor to Greater = Add). Logically if you are moving from a higher to lower, you are obviously losing counts or subtracting, and it's the opposite if you are going from Lower to Higher. I hope this help some folks out there... (US Army, SSG-54B30).

is this lindy biege?

An Aussie from Down-Under here, and I've been observing the deviations of the North Magnetic Pole for nearly 2 years now. Over this time, my observations had mainly been almost daily rocking back and forth 2 or 3 degrees West than back East of True North. But then, a few weeks ago, in ONE DAY, the North Magnetic Pole SHIFTED a full 11Degrees to the West of True North - and STAYED THERE! My son in Vancouver, Canada, has NOT noted any movement in his Compass and this is consistent with the fact that from his location, the North Magnetic Pole IS actually moving away from Canada in a 'Northerly' direction, thus it's movement can't be tracked from his location. BTW: the Southern Magnetic Pole has currently left Antarctica and is now moving in a NW direction towards the Indian Ocean. We live in interesting times!

Duct tape works fine as electrical tape. They just keep stuff from touching, right?

👏🏻👏🏻👏🏻👏🏻👏🏻

Great video! My only concern is that declination changes. For some reason it’s speeding up. What might be 5 degrees this year might be 8 degrees in 4 years. If you don’t mind buying new maps every now and again, that’s no big deal. It’s something to be aware of though.

Demo very well done for a great device on land and what about under water sir?? 💦

I love this!

Excellent and simple explanation. I use the MC2G myself and love it. Thank you for sharing. Cheers from Australia.

Why evverbuddy want to go north? Is Santa Claus gonna give them a sleigh ride home? Seems kinda way fa.r out of the way

I loved this. Thank you for your service in the Marines, for your wife standing in rain with you protecting the camera and for a really wonderful idea for folks

Thank you!! Excellent job teaching my brain to understand and remember how to deal with and understand declination. Now I want to understand North star vs magnetic north.

What kind of tarp should one use to not be toxic (for the use of showers and dish washing in an RV) ?And, any tips for winter time? We will be roughing it in an RV for the winter where we get a lot of snow. I'm wondering how to melt and use it and keep from freezing, if you have any tips. Great video- I will be trying this ASAP!

An excellent video with excellent information. I just have one suggestion. It may be helpful to add some thread or thin string to be used with the needle/awl. Thank you for the new ideas!

Thanks for the great idea. I live off-grid in West Virginia. I'm always looking for new ways to save rain water.

Run 2 heavy chains from back corner stakes to buckets to hold your green sheet from flapping. Tie your rock to the end of one. A triangle tarp and one chain might work ok too. Good job.

The best explanation. Thank you Sir

Thanks for the tips!

Why wear two watches?

Verry clear explanation, but what about 1. aligning the rule with the magnetic declination at the bottom of the map gives error. 2. drawing all other lines gives cumulation error. 3. declination changes over the years so you have to erase the lines and draw new ones.

Muy bien video

It's been 55 years since I was a young Marine Infantry Officer running patrols in the mountains along the border with Laos in I Corps. I don't get out in the bush any more but i was driven to rehash my map and compass technique and I vaguely remembered the techniques taught by this former Marine. Anyone thinking about hiking in the woods should watch this video. This stuff saved my life in the Ashau Valley when i ran patrols back in "69". Semper Fi !

This is the best explanation I have found thank you very much it now makes sense.

@2:10 is what you want to see

Absolutely best explanation and practical guide to handling declination when navigating via map, well done!

Your transferred knowledge lives forever. Thank you
