RAnGE ESTIMATInG WITH VX-III SCOPES

Selected VX-III scopes have a built-in range estimator. This system uses the
Duplex ® 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
