It is a skill set that is reduced markedly over the years since phone apps and hand held GPS.

I love maps, always have a bunch of topos jammed in the pockets in the car above my head of where I'm going.
Gives me comfort knowing I have several folded pieces of paper with lines printed on them.

Magnetic variation is what you need to know to either adjust your compass bezel or adjust your track to magnetic north.

Magnetic declination is the angle between true north and Magnetic north.

Any decent map would (should) have a notation re: declination.
Another silly thing is using a compass whilst anywhere near metal. Even sighting down a barbed wire fence is fraught with danger. There's a few natural perils to be aware of too. Thers a mountain in SE Qld that has a variation of 12°

I'm no maths expert, but I assume the higher you are off the ground, the further you have to travel to rotate the Earth.

So many innocuous, metalic objects can affect the accuracy of a compass, from a vehicle to the metal in a bra.

Ok.........

Yes, I always use to make sure my Bra had no metal parts when I was flying. Not sure about the metalic ones though.
