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.

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.
2 LIQUID 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.

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!
