Measuring horizontal angle using the reticle
An M22 reticle built into these binoculars enables
measuring height, distance and size of a target, as well as
angle between two close targets. Though reticle
appearance may differ from one model to another as
described in 3.2, the description below is valid for all
models.
When the angle between two targets is smaller than the
angle measuring range (100 mils), aim the scale line at
one end of the reticle at the target then read the value of
the scale at which another target was located on the
reticle. As shown in Fig. 4, the horizontal angle of
the target (tank) is 20 mils.
