Silva 1-2-3 System

2. Rotate the compass housing until N on the dial

points North on the map. Check that the compass

housing red/black north/south lines are parallel

with the maps meridians.

NB! If using a mirror-sighting compass – angle

the mirror/lid approx. 45 degrees towards your-

self and hold it with straight-arm in front of you.

Now, at the same time looking in the mirror to see

that the compass needle aligns with the red/black

N/S arrow, sight above the mirror (using the sight)

towards an object in the eld in line with the direc-

tion of travel.

3. Hold the compass in your hand and turn your-

self until the red end of the compass needle

(North) coincides with the red arrow in the bottom

of the compass housing. The front of the compass

with the direction of travel arrow is now pointing

towards your destination.

1. Place the compass on the map with the edge

of the compass along the desired line of travel.

I know my position on the map and would like to go to a lake in the forest, which

I see on the map – how do I do?

The easiest way to set a compass course towards the lake is to use the Silva

1-2-3 System. It is a simple and safe system used by navigators such as expedi-

tions, youth organisations, mountain-guides, armies, orienteers etc all over the

world and it is the main reason for Silva’s market leading position.
