DECLINATION 

Magnetic Declination is taken from numbers provided on maps 

and/or charts that apply to a specific location.  The numbers 

represent the easterly or westerly angular difference (Declina-

tion) in degrees between magnetic North and true (geometric or 

polar) North.  A Compass will point to magnetic North unless its 

reference is adjusted to true North prior to conducting activities.

The Declination Menu displays the graphic SEt with selections 

OFF, East, and West (Fig. 152).
