No ... it is a non electronic one.. other than the standard: (but then you will know all about this... )
Calibrating your Compass for Magnetic Declination
Different areas on the globe have a different magnetic declination which is basically the difference between magnetic north (where your Compass will point to) and true north (the direction where north really is). There is a difference because the magnetic north pole lies about 1000 miles below the true north pole. So the declination differs per location on the globe. In general, the further north you go, the bigger the declination becomes.
