SILVA

1-2-3 SYSTEM

Over the years, Silva has become a reliable and trusted partner among defense

forces, expeditions to the remotest parts of the globe, and the orienteering

and adventure racing communities. One reason for this vote of confidence is

the Silva 1-2-3 System

that enables you to take and walk a bearing in an easy

and accurate way. The popular system evolves this year with colour-coding on

the Field 1-2-3 Compass, a new memory tool for both educational use and the

infrequent navigator.

I KNOW MY POSITION ON THE MAP. HOW DO I GO TO A LAKE IN THE FOREST THAT I SEE ON THE MAP?

The easiest way to set a course towards the lake is with a simple and safe system used by

expeditions, youth organisations, mountain guides, armies, orienteers and other navigators

the world over: the Silva 1-2-3 System

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.

1. Place the compass on the map

with the edge of the compass

along the desired line of travel.

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 map’s

meridians.

3. Hold the compass in hand and

turn your body 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.
