Silva 1-2-3 System:

  1. Place your compass on the map and use the baseline to make a straight line between your current position and your destination. Make sure Direction of Travel arrow points towards your destination.
  2. Turn the compass housing until the red part of the north/south arrow is parallel with the map meridians and points north on the map.
  3. Lift your compass from the map and hold it horizontally in your hand. Turn yourself and the compass until the red end of the needle is inside the red north/ south arrow. Now the direction of travel arrow will point towards your destination. Take a landmark and start moving. Enjoy!
  4. NOTE: If using a mirror-sighting compass: angle the mirror/lid approximately 45 degrees towards yourself and hold with straight arm out in front of you. Now, while looking in the mirror to see that the needle aligns with the red/black N/S arrow, sight above the mirror (using the sight) towards an object in the field in line with the direction of travel
