SILVA 1-2-3 System

Thumb compasses

The easiest way to use a map and compass together is to orient the map towards North. Simply align the map meridians with the compass needle so that “up” on the map is pointing North. Now everything on the map is in the same direction as on the ground.

Easy as 1-2-3!



Place your compass on the map and use the baseline to make a straight line between your current position and your destination.

Make sure the sighting line points towards your destination.


Turn yourself and the compass until the compass needle is parallel with the map meridians and the orange/red part points north on the map.


Now the sighting line will point towards your destination. Take a landmark and start moving. Enjoy!


In step 2 – turn the compass housing until the orienting lines are parallel with the map meridians.
In step 3 – Lift your compass from the map and turn yourself until the needle is aligned with the orienting lines. Now the sighting line will point towards your destination.


After step 2 – note the coloured reference point that the needle is pointing at.

In step 3 – the sighting line will point towards your destination as long as the needle points at the colour marking from step 2.
