The Meopta H75 30x WA-R is a fixed power wide-angle eyepiece, which has been designed for the Meopta TGA 75. What makes this eyepiece unique is that it has been fitted with a ranging reticle (cross) enabling the user to estimate the distance of the objective being observed.

>Using the ranging reticle to estimate distance:

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 estimated height of an adulat Roebuck body trunk is 0.5 m and with angular height in the reticle screen as seen in the reticle picture just below this description is calculated as follows: D = 1000 x 0,5 /h = 125 m.
