I doubt very much that this is what Dave Weilacher wants. I thought that I
had explained in my message re: Magnetic North Pole of Jan 11, 2002 that a
magnetic compass does NOT point into the direction of the magnetic north
pole.
Incidentally, in the same message I already gave an answer also to Dave's
more recent question about "sources to determine compass variation for your
position at sea". The official source is still DMA chart 42, "Charts of the
Earth's Magnetic Field". If you look at this chart you will see very clearly
why a magnetic compass reading cannot be interpreted like one from a radio
beacon finder.
