Congratulations! You have purchased a Leupold
®
RX
™
Series digital
laser rangefinder that has been designed by Leupold’s engineers and
designers to be the best rangefinder on the market and to provide
you with years of solid performance in the field. Following are
detailed instructions regarding the proper use and employment of
your RX Series rangefinder. To ensure top performance for the life
of the product, please read these instructions before operating your
RX-I, RX-II, RX-III, or RX-IV.
Your new Leupold RX Series digital laser rangefinder is a
revolutionary, range-finding device that incorporates advanced
digital electronics with state-of-the-art ballistics algorithms. RX
features include an inclinometer, thermometer, compass, and the
Match 13
™
Reticle System
™
, but the truly innovative and unique
feature is True Ballistic Range (TBR
™
), which is available on RX-II,
RX-III, RX-IV, RX-IV Boone and Crockett
™
, and RXB-IV
™
models.
True Ballistic Range
™
algorithms were developed by the same
engineers who developed Sierra Infinity
®
Exterior Ballistics
Software and who helped develop navigation and guidance
systems for ICBMs and other missiles with far more demanding
trajectory requirements than a hunting bullet.
True Ballistic Range (TBR) is a marriage of laser ranging, inclinometer,
and an advanced computerized ballistics program. The result is
distance measuring precise within a yard, no matter the angle at
which the laser is fired.
Bullets and arrows travel in a ballistic arc,
yet conventional rangefinders only provide a linear distance to
your target. True Ballistic Range delivers the ballistic equivalent
range to the target, accounting for the effects of inclines (either
up or down) on the path of your bullet or arrow. Other features
that are provided for firearms are outputs that display either MOA
adjustments, or inches/centimeters of holdover at that specific
distance. True Ballistic Range eliminates any potentially significant
error, and provides a precise range for your aiming calculations.
TBR is matched to each of seven firearm ballistics groups and three
archery ballistics groups, allowing use with most popular firearms
and bows. RX-IV Boone and Crockett
edition rangefinders add the
ability to accurately judge the width and height of a target using
Trophy Scale
™
as well as showing the exact aim point to be used
with your Boone and Crockett
™
reticle.
The ranging accuracy of all Leupold RX Series rangefinders is +/- one
yard/meter. The maximum range of the unit depends on the
reflectivity of the target (as do all rangefinders). Following is a
reference table listing the ranges of the various models under
different conditions:
Surface texture, color, size, and shape of the target all affect
reflectivity, which in turn affects the maximum range of the
instrument. As a rule of thumb, brightly colored targets are much
more reflective than darker targets. Tan game coats are more
reflective (and thus provide a more solid reading) than a black roof.
A shiny surface is more reflective than a dull surface. Smaller targets
are more difficult to range than larger targets. Light conditions,
haze, fog, rain, and other environmental conditions can all affect
ranging performance. Any factor which degrades air clarity will
reduce the maximum effective range.
