You got it mixed up. The compass does not show you the TRUE Geographic reading. That is why you have the magnetic deviation charts to compensate for your area.

For example: In Columbus, OH TRUE SOUTH is 184 degrees. So when you look at the compass, you should point to 184 NOT 180.

TRUE SOUTH Values:

184 Magnetic = 180 Geographic (for Columbus, OH)
166 Magnetic = 180 Geographic (for San Diego, CA)
194 Magnetic = 180 Geographic (for NY, NY)
