observer and the target using the formula. For
example:
There is an adult whose height is 1.70m.
(H= 1.70m)
The upper and lower angle of the adult is 0 - 40
mils (K=0 - (-40))
L=H/K= 1.7/40=0.0425km=42.5m
Therefore: the distance between the observer
and the adult is 42.5m.
4.2.4.B How to measure distance directly using
the reticle in (Fig. 7)
For example, if the target is 2 meters in height,
place the lower part of the target at the horizon-
tal line on the reticule with the upper top part
of the target against the angled scale line. The
reading on the top of the target. Where the top of
the target or image touches the top of the angled
scale line is the distance between the target and
the observer, (line value : 100m)as shown in fig 7,
