HOW TO USE THE RETICLE
The vertical scale (reticle) visible through the left half of the binocular, above the compass display,
allows you to calculate distance to an object if you know its height, or to calculate the height of an
object if you know its distance from you. Each mark on the vertical scale has a value of 5 MIL (1 Mil is
equivalent to an angle that can determine an object one meter in height at a distance of 1000 meters).
Therefore, if a navigation chart gives the height of an object, by sighting on it and counting the number
of MILs, you can determine how far away it is. Here are the two formulas (note use of metric units):
