1WRIST BAND
With the compass attached to the wrist, you get both
hands free, which gives you more flexibility when holding a
map, scrambling on rocky ground etc. The wrist compass
can be used on either left or right hand. The compass band
is strapped at the base of the thumb; the thumb serves the
function of a baseplate when taking and sighting bearings.
The wrist band is adjustable for optimal fit.
2LIQUID FILLED CAPSULE
The capsule is filled with anti-static liquid (customized formula) that ensures
clear reading, fast settling time, perfect dampening, stability and accuracy of
the needle.
3COMPASS NEEDLE
The magnetic needle features a combination of a sapphire jewel bearing and
a hardened steel pivot that minimises friction, which in turn gives rapid and
accurate movements. Magnetic North direction accuracy: 1 degree. The orange
end points to magnetic north!
Our wrist compass needles come in two dierent versions:
JET needle: The world’s fastest needle, highly transparent for extra map visibility.
Steel needle: Swedish high quality, stainless steel, stable and distinct

With basically the same features and user area as a thumb
compass, but placing an even greater emphasis on speed
over accuracy. The wrist compass has no baseplate. It con-
sists solely of a needle capsule strapped at the base of the
thumb. The thumb serves the function of a baseplate when
taking and sighting bearings. The wrist compass can be used
on either left or right hand. It is often used for city/park race
orienteering, MTB orienteering or Adventure racing.

HOW TO
NAVIGATE
ORIENTING THE MAP TO NORTH
The easiest way to use a map and compass together is to ori-
ent 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. When travelling along your route, remember to
keep the map oriented at all times. By doing this it will be very
easy to follow your route since turning right on the map also
means turning right on the ground! Properly orienting the map
is quick, easy and the best way to avoid unnecessary mistakes.

10 SPECTRA SYSTEM™
The SILVA Spectra System™ is developed to simplify your orienteering, enabling you to
be faster and more accurate through the forest. No matter if you are an elite or leisure
orienteer - the Spectra System™ will help you by letting you stay on the right course at
high speed while reducing mistakes.
The Spectra System™ consists of coloured reference points and dots on the capsule
that are easy and quick to read and memorize.
You will become faster by navigating more accurately, if you think more clearly. During
periods of high stress and extreme physical work we know that the brain does not
get as much energy as at rest. Sometimes you think less rationally. The tougher the
work, the harder it is to make the right decision and do the right thing - quickly. To think
clearly, you have to keep things simple.
With our Spectra compasses you have an easier system and clearer reference points,
which help you keep the right directions at competition speed.
USING SPECTRA WITH THE 1-2-3 SYSTEM:
1. Place your compass on the map and use your thumb to make a straight line between
your current position and your destination. Make sure the thumb points towards your
destination.
2. Turn yourself and the compass until the compass needle is parallel with the map me-
ridians and the orange/red part points north on the map. Note the coloured reference
point that the needle is pointing at and memorize it (for example blue, one dot).
3. Your thumb will point towards your destination as long as the needle points at the
colour reference point from step 2 (blue, one dot). Take a landmark and start moving.
ADVANTAGES WITH THE SPECTRA SYSTEM™:
• You don’t need to hold the compass orientated on the map, in order to travel on the
desired bearing.
• You can run on a compass bearing at high speed.
• Taking the step from using the traditional base plate compass to using a thumb
compass is made easier.
• You have more freedom to choose whether to run with the map and compass in the
same hand or with the compass in one hand and the map in the other.
• The use of colours and dots as reference points reduces the risk of making mistakes
at extreme levels of physical and mental fatigue.
• The use of colours and dots makes the teaching and learning of how to use the com-
pass easier. It simplifies the explanation of how to use to map and compass youths
and beginners.
• The colour segments are easier to find and focus on, especially at high speed and
you can correct your direction without stopping.
• Now it is possible to make an accurate compass run with a thumb compass.
TAKE CARE OF YOUR COMPASS
A SILVA compass will, if treated carefully, be a navigation partner for many, many
years. Always check that your compass is functioning properly before heading out.
• Never expose your compass to extreme temperatures (high or low) – this can
deform the plastics with a leaking compass capsule as a result.
• Avoid dropping the compasses on hard surfaces and handle it with care.
• Don’t store or place the compass close to strong magnetic fields such as knives,
mobile phones, radio speakers, magnets etc. This can cause reversed polarity of
the compass needle which will result in it pointing south instead of north.
