6.3 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.
