3rd Method
1. Turn the fully opened compass and rotate the Bezel to
align the lights in the case cover with the Luminous Bezel
Indicator.
2. Rotate the Bezel counterclockwise to the azimuth desired.
Each distinct click of the Bezel represents 3 degrees.
Example: you want to follow a course of 120 degrees. Divide
120 by 3. The result is 40: therefore, rotate the Bezel 40
clicks counterclockwise.
3. Turn the compass until the North arrow lies directly under
the Luminous Bezel Indicator. The direction indicated by the
lights in the case cover points the desired course.
E. PROCEEDING ALONG AN AZIMUTH
1. With your lensatic compass pointing along a desired
azimuth, find an easily identified object that is in line with the
Sight Groove of the Lens Bracket and the Sight Wire (fig. 2).
This "steering mark" should be distinct from surroundings. It
should be visible at all times along the route and should be
identifiable when reached.
2. If your steering mark is lost to view, stop, re-sight and
select a new steering mark immediately.
3. If a good steering mark is not in line with your desired
azimuth, select an alternative steering mark off to the side.
See fig. 3a.
