Hi,
Once again I am surprised by your answers.
How do you "adjust" for variation?
Is not still part of the acronym TVMDC- Timid Virgins Make Dull Companions or True, Variation, Magnetic, Deviation, Compass?
When using a Magnetic compass for real you usually have to work this little equation backwards to get the true bearing.
When I was learning I was also told that you should also regularly take Azimuths to confirm the accuracy of the Magnetic Compass as a whole.
