Measuring the azimuth (horizontal angle)
The azimuth measures the horizontal angle and cor-
responds to the horizontal deviation from the north.
Using the MIL crosshairs you can read off the hori-
zontal scale value. In the illustration the azimuth of
the observed object at 6 MIL (4 MIL + 2 MIL) can be
simply determined using the horizontal scale value
(see measurement of elevation angle).
Determining the length of an observed
object when the distanceis known
On the basis of the measured elevation angle or azi-
muth angle the height or length of an observed object
can be determined using the following equation:
Example for calculating the object length
It is a preprequisite to know the distance. In our ex-
ample this is 1,100 meters. The scale value read off
the reticle plate is 6.0.
This is then calculated as follows:
1,100 meters x 6.0 divided by 100, resulting in an
object length of 66 meters.
Using the compass
Your MINOX BN 7x50C has an integrated analog com-
pass that shows the bearings in degrees. North has
an azimuth angle of 360°, east is 90°, south is 180°
and west has an azimuth angle of 270°.
Determining your position with the compass
With the following example your can determine your
position using a map and your compass binoculars.
Azimuth angle = Horizontal angle
Length of observed object (m) =
Distance (m) x azimuth angle
