RANGE ESTIMATING WITH VX-III SCOPES

Selected VX-III scopes have a built-in range estimator. This system uses the
Duplex® portion of the reticle in combination with an additional set of numbers
on the power selector ring. (Also see the Leupold Range Estimating Reticle
Instructions for other reticle types.) In scopes with this feature the space between
the tip of the thicker post of the Duplex reticle and the center of the reticle covers
16 inches at 200 yards (the size of a Whitetail buck from backbone to brisket).
NOTE: The Duplex reticle was designed to estimate ranges based on the backbone
to brisket dimension of a Whitetail buck. The distance of other game with a body
dimension that is known to be 16 inches (or 32 inches if the measurement is taken
from post to post instead of post
to crosshair) may certainly be
estimated. It is necessary to know
the approximate physical size of
your target whenever you
estimate range.
