    15 Example: Let's find size of the segment (E) of the thin cross hair at 100 m distance with 8 x magnification. The specified step at 100 m distance and 12x magnification is1 0cm. Now we shall calculate its size a t 8x magnification: E = (10 х 12): 8 = 15 cm at 100 m. The distance to the target also influences the corresponding sizes of the r[...]
