30x Wide Angle Ranging Reticle Eyepiece for TGA 75
The dash lines placed from top to bottom on thin lines subtend the angle of 1 m at 1000 m, i.e. 1 milliradian. In military terminology this angle is called 1 mil. The distance D can be determined by a simple calculation using the formula D = 1000 x H / h, where H stands for the actual target height in meter and h stands for its angular height in scale divisions. For precise range finding it is necessary for the user to know the exact or estimated target height. For example, the estimated height of an adult Roebuck body trunk is 0.5 m and with angular height in the reticle screen as seen in the illustration below the distance is calculated as follows: D = 1000 x 0,5 /h = 125 m.
