2.4 RETICLE USING
2.4.1 BINOCULARS RANGEFINDER RETICLES
The reticle has horizontal scale and vertical scale, in the below there is measuring reticule
according to the known height (see Figure 4). Vertical and horizontal lines on the reticule is in mils
as unit. Each small division on both vertical and horizontal lines represents 5 mils and each big
division represents 10 mils. You can obtain the azimuth angle, upper and lower angle, distance and
height or width etc. by using this reticle. The fast distance measurement is regards as the target
as 2 meters high to measure the distance quickly.
2.4.2 HOW TO USE THE RETICLE AND CALCULATOR DIAL
1) How to Measure the Horizontal View Angle
The azimuth angles is the angle included between two objects to be measured at the horizontal
direction of the binoculars.
A. When the Horizontal View Angle is smaller than the horizontal scale range (-50~+50 mils) inside
the binoculars, aim one edge of the object at a horizontal scale line(the center or the outmost line
are selected according to the image size of object usually) and read its value. Then read the value
of the scale at which another edge was located. Add, these two values, the sum value is the
measured Horizontal View Angle. As shown in Figure 5, the Horizontal View Angle of the target
(tank) is 20-00 mils, and the Horizontal View Angle is 20 mils.
