I've been watching some compass/map youtubes, and want to be sure I'm setting the declination correctly. The east/west part is confusing me a little.
I'm setting my compass for the Sierras -- Lake Tahoe area, where the declination is 13 degrees east. If my understanding is correct, this means that the compass needle is pointing 13 degrees east of the North/South lines on the map. (I know, there's also grid north, but I think I can ignore that for my purpose)...
The youtubes look like they're telling me to set the adjustment so that the red arrow (suunto orientieering compass) is to the right (east) of the north cardinal point by 13 degrees. Is this correct? Seems to me that, since I started out with the needle pointing 13 degrees too far east -- now I'm going to be 26 degrees too far east. My thinking is that I should set the pointer to the west by 13 degrees to compensate for the fact that I started out 13 degrees to the east.
Help!? Thanks!
