---------ABOUT THE VIDEO---------
In this video, we explore the process of correcting magnetic compass bearings to turn them into true bearings.
We discuss the concepts of Variation and Deviation, and see how to apply them in some worked exampls.

Finally a video with a nice diagram explaining the logic behind east/west magnetic declination calculation. Thank you VERY much! Such a simple concept but I had been getting really confused until I saw your video.

@odaisednesday Час назад

So much thanks for your video!!! the diagram explains gives me know deeply about the CDMVT knowledge.

This is the best video on this subject. As an aviator, i appreciate your explanation. Thank you.

"True Vicars Make Dull Company." Not the one I remember, but then I didn't think you'd be sharing that one on your channel. But mine helps to remember which direction you can add because you finish it off with "add Whisky, take away Ethics". Love your videos! Would you consider doing a video along the same lines but with interpolation for the deviation?

I realised I would have to change some of it to keep the RU-vid policies happy

Thank you for video, just want to comment on one thing because i was lost for a moment their. On the second part CDMVT, you should’ve emphasize that deviation can only be applied on magnetic course, because you said C applying D will get you M, but it contradicts the explanation on your diagram, i tried to explain as best as i can, anyways thank you so much

@rael5469 4 месяца назад

Wait.......deviation is local. So how do you swing a compass and create a compass deviation card at a given location, so that it will be useful to the user at different locations that have different deviation values?

Thanks Master,you hâve a gift of transmission of knowlege, thé only very good explanation about CDMVT on RU-vid since. May God bless you.

If I had a true course of 015T Variation 20E Deviation 3W how would you present this using your diagram here is another example Ships Heading 353T Var 20W Dev 5E using the acronym not a problem.

army does this. all topographical maps should have a plus or minus a certain degree. If i remember right Fairbanks ak was negative 21

@averagejoey2000 2 года назад

how can one feasibly swing a magnetic compass which is a bubble style? For instance, my sailboat's only compass is a Ritchie Globemaster, and the previous shipowner has lost her deviation card. I'd like to create my own deviation card, and keep a compass record book of sun and star azimuths, as a prudent Mariner should. I unfortunately can't find any type of sighting device that works with globe compasses, only the ones that work with flat compasses like gyro repeaters.

@RefreshMaritime 2 года назад

I think the only way would be to line your boat's heading up with a known bearing line, then repeat for as many different bearing lines as you can. You could work out the true bearing using either GPS, leading lights, sun or star aziumths. When you collect enough, it should produce a reasonable deviation card.

@averagejoey2000 2 года назад

@@RefreshMaritime ah, I see. and this would likely shut me out of visual fixes with multiple bearings, I gather

I think this is the best and precise method to restore compass deviation table: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-iIRLTyp8vhg.html

Just follow the compass . Earth is flat and north is north . This is all nonsense

Wtf . Have you ever know about something called North Star how someone like Robert norman knew that 500 years ago and you are in 21 century thinking like this
