* Calculated Azimuth values are adjusted for Magnetic Declination
39
The values you see are what you should use with your compass
40
*I would like to express my appreciation to The Cooperative Institute for Research in Environmental Sciences of the University of Colorado,
41
NOAA's National Centers for Environmental Information for the program calculating Magnetic Declination. See them at geomag.colorado.edu

The Magnetic North Pole is drifting westward. The CORRECT value calculated above may not agree with an old value you have.
43
Remember that local iron deposits, vehicles, structures, and electrical transformers can also affect the accuracy of your compass.
