Please note: When looking through your MINOX
BN 7x50 DC/DCM, you will see a horizontal graticule
consisting of pixel dots. One pixel equals one mil. The
distance from one vertical line to the next is approxi-
mately ten mil. The azimuth is the sum of all pixel dots
along the graticule depicting the length of the object
being viewed (fig. 6)
Determining length
The distance to an object must first be known:
Distance to object (m) x HA
= length of object (m)
In this example, the known distance is 1.100 meters.
The horizontal angle is 40 mil (each pixel is equivalent
to approximately 1 mil). 1.100 x 40 divided by 1.000
results in an object length of 44 meters.
Determining distance
The length of the object must first be known:
Length of object (m) x 1.000
HA
1.000
= distance to object (m)
In this example, the known length of the object is 44
meters and the horizontal angle is 40; 44 times 1.000
divided by 40 results in a distance of approx 1.100
meters to the object.
Horizontal angle (HA) = total sum of pixels
along the length of the measured object
A reading can also be taken in the horizontal graticule
compass mode (fig. 5) to make approximate object
height calculations. The vertical line in the middle can
be used to determine the approximate height of an
object. Each pixel is equivalent to approximately 1 mil.
If necessary, the binoculars can be turned vertically to
allow for more scope of measurement.
distance (m) x VA
= height (m)
1.000
Vertical angle (VA) = total sum of pixels
along the height of the measured object
Important note: the readings made with the hori-
zontal graticule are meant only to be approximate.
Various factors must be taken into consideration like
atmospheric moisture (resulting in objects appearing
