Because of the coming micronova, declination is moving much farther, and much faster and so declination information is likely incorrect 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. My up-to-date declination is 30 degrees, 15 degrees off from the official declination for my area. More on micronova in my 2nd book, Surviving the Micronova: This Train Is on the Tracks will be available in September.
Exactly, declination particularly over distances is crucial, and it varies with regions, and with the earths magnetic field fluctuations, which is why you should never set off into any remote wilderness with an old out of date map...current variations can be found by Googling official sites. Also, the step method of calculating distance is at best guesswork particularly when in Jungle or Forestry where you move in an erratic path around obstacles so any paces measured are inaccurate anyway....
Very good; easy to understand and a little above basic.
Be safe guys

how about dealing with grid north/magnetic north differences?
Who cares

Where do you get these topographical maps
We are assuming that the compass is declined to we’re you are at
Thanks for sharing.....
Will this help me with my putting??
If 0.8 / count, 100m is 125 count, right? Am I wrong?
thanks
1st and p.s cool vid, could you do a review on the vango eos 550xl?

No mention about declination. Dangerous!!!
Not calculating and adjusting for Declination , is a seriously dumb move.
someone should tell Sliva to go for Key Stage 3 at least
Everyone who has account has be over 13 for christ sake
Was it necessary to blaspheme?
