2:22 - The international date line isn’t straight up and down, as the map and narration would indicate. This isn’t important knowledge for most of the planet, but for the areas it affects, it’s profoundly important.

Good information, thank you

Just dumped GAIA, it got pathetically expensive for $60/month. Going back to their competitors, which are way more friendly to use.

👍👍👍

Great series. I was trying to brush up after not doing much, or really any, of this for decades. Your explanations were great! I think my dog and I will head out to the bush and try it out. She tracks so surely between her and a compass we will make it back. Thanks for your time and continue making the series.

Great explanation of declination, and great series on map, compass, and GPS usage. Thanks for your terrific work on these videos!

The best explanation on RUclips. I have a question about input of UTM coordinates into Garmin device. Easting is one digit less (6) than Northing (7). So do I have to put 0 before Easting? Thank you

I appreciate the content, but thought I should point out that most cell phones(at least when I last checked) do not have true GPS capability. They are dependent on signal from cell towers to estimate position. Some use a hybrid system, and others rely solely on built in GPS receivers. I suggest that if anyone is going to rely on a cell phone for location information, they should research the GPS type of that phone before doing so.

Thank you! Great video to help me clarify a few things

Is it possible to disable all text and other overlays to only get topographic information?

Excellent explanation of what UTM is and how to use it. Many thanks for putting this together.

I want to download it

Nice job! 👍

very helpful

That would be crow flying distance.

Have a question that no one seems to have an enswer for. I'm sitting in Virginia, declination here is 8 degrees west. Planning a trip up Mount Shasta in California, declination maybe 12 east. I want to make a "plan" with travel points with azimuths/bearings in case of low viz or GPS failure. Can I do that? Do I set my declination on my compass for 8W or 12E

Just a note, some compasses have the adjustment screw on the front side ( not all are on the back).

Why this just popped up after I had searched forever trying to learn about declination and finally understanding it I’ll never know, because this was probably the best explanation out there. After a few emails back and forth with a cartographer at USGS I was good. Great video

Helpful series. Thanks a bunch.

Great video. I liked the compass hack very much. 👍

Very helpful video. Thank you!

Thanks for all you help John! These videos are nice.

Great explanation! Best I have seen! Well done! I get it now 😅

Amazing presentation

Fab 🙌🏼 thanks for doing this video helped a lot

Do you know how many videos i viewed on this subject while pulling my hair out in frustration, trying to understand the (well meaning but) poorly communicated explanations and ultimately coming away more confused. Thank you so much for your demonstration's brevity, clarity and functional illustration! Had I seen your video first, i would have enjoyed hours of practice that now I'll never get back!

I’ve just been binge watching your navigation videos and really enjoying them. I’m in San Diego and have a 13° easterly declination so if I was going to take a bearing with my compass I want to add 13°. However, one thing I find very strange is that no one on RUclips really talks about if I wanted to take a bearing from my map and transfer it to my compass I would actually want to subtract 13°. I think this is where people get confused with declination and East is least & West is best. I’ve been searching and hoping to find a video out there that explains why you need to reverse the declination whether you’re taking a bearing from a map versus a bearing on your compass. Can you offer any insight on that? Thank you!

To the users of the iphone built-in compass app: do not forget to switch in the settings (Settings->Compass) to read the TRUE north rather than the magnetic one

Best well documented presentation I have discovered thus far. I am going to your web site next. Thank you so much.

Thank you so much! This is the clearest explanation I've come across on how to set the declination on the Suunto M-3 compass.

This was a great video.

Excellent explanation!

Good clear instruction.

Very clear explanation of the map scales, thank you

Because of the coming micronova, declination is moving much farther, and much faster and so declination information is likely incorrect My up-to-date declination is 30 degrees, 15 degrees off from the official declination for my area. but there is still a way to recalibrate magnetic declination using the shadow of sticks recording the path of the sun---rotation of the earth has not yet changed. First stick will show East. Mark it with a sharp stick pushed in. After a few minutes you can mark sun shadow travel where the shadow has moved - Push another stick in to mark West. Lay a straight stick from the E mark to the W mark. Geographic north or True North is 90 degrees from the E-W line. With your compass pointing toward True North, note how far off your compass is now. That is your true up-to-date declination. More on micronova in my 2nd book, Surviving the Micronova: This Train Is on the Tracks

This compass is now $73 (REI) in 2022. I have a Suunto MCB Amphibian Compass and it does not adjust in the back. This compass has certain features I can't find in others. Can't seem to find a used one for cheaper online. These lessons are great and appreciated. I was worried when trying to learn using the compass I have. Lesson 9 here went a bit out the window for me since I can't adjust it. I continued onward though, and appreciate the tips for the "frugal" compass owner mentioned in lesson #10. But, I can see myself making an innocent but dreadful mistake, so I will either shell out for the $73 or find something else with the adjustable feature. Thank you so much!

That's probably the first video I came around that properly explains how to adjust declination in easy to understand manner and without tons of garbage talk. Well done!

Great explanation of declination! Everything you explained was in layman's terms and not confusing at all. I have watched countless videos on the science of declination; however, just like many folks here, I was left more confused than when I first started researching this phenomenon. What lead to my confusion with other youtubers, was that some would state that you didn't have to adjust for declination when taking a bearing if you first orient your map. Others would state you do have to adjust for declination no matter what. So I didn't know what to believe in the end until I watched your video. Thanks buddy and God bless! :)

Thank you. This is great.

Nice!

Thank you VERY much for this video!! It was very useful and saved a lot of stress.

This looks super “proprietary.” It does not seem to work on Apple. I see major challenges with logistics (battery power, uncommon sized printer paper, numerous support devices to make it work, etc). Trying to use this in a remote 3rd World Country to train land navigation skills for individuals would appear to be MUCH easier and less burdensome with manual punches, paper and a watch. Am I missing something?

Well done-this “newbie” greatly appreciates your material!

What a lucid, intelligent, organized professional presentation! Damn! Bring it, whoever you are. Really enjoyed it, and actually learned a lot.

Thumbs are curved, and the width changes as you go from the tip of the thumb down to the widest point. John covered the scale with his thumb somewhere between the tip and the widest point, and unless you place it the exact same way every time, there will be significant variations between measurements due to the variations in your thumb's width.

Very clear and helpful - thank you!

Very good. In 2022 the layout is different but this still helped a lot
