If so, the chances are that you failed you failed to adjust correctly for magnetic declination (aka magnetic variation). Our goal is toaddress any negative stigmasor anxiety around using a compass and map that is often a roadblock for both new and experienced outdoor explorers. For a west declination of say 16o (i.e., declination is 16o west of true north), turn the card west, i.e., counterclockwise (by turning the screw) so that the index pin points to 16o on the side of the card marked with 'W' in the quad scale, or 344o in .

How would you take a bearing or heading if you were between the magnetic north and true north? Also, my compass (Suunto M-2 I think) requires a tiny tool to set mag. Magnetic declination changes over time and with location. The GPS receiver should now be set to provide direction information (e.g., bearing and heading) in degrees true. stream The geographic position is N6.1884, W10.4832. Whenever you transfer a magnetic bearing taken in the field to your map, you add the magnetic declination to get the true bearing. Taking a strike on an inclined surface.
