By skillfully handing the compass the Arming line(3)
corresponds to the Aiming Point(15), thus ensuring that
eyes,compass dial and object are at same level and
resulting in utmost accuracy.This method allow to read the
fraction of an angular degree.
Adjust the position of the prism or lens which on the 360°
Rotating Bezel Ring (9 ) until you see distinctly the numbers of the compass card(13 ).In models with adjustable
eyepiece,the Sighting Lens(16) must be rotated until numbers in degree are clearly visible.
Optimeal results are obtained when you keep the compass at a distance of 1-2cm from your eyes.

HOW TO FOLLOW THE VALUE OF THE MARCHING DIRECTION YOU DEFINED
If the value of the marching direction is known,look at the compass card(13) and turn around until said value
