innovative and unique feature is True Ballistic Range (TBR ), which is available
™
on RX-II, RX-III, and RX-IV models.
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 ballistically
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 ballistic groups and three
archery ballistic groups, allowing use with most popular firearms and bows.
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). Below is a reference table listing the ranges of the various
models under different conditions: (see page below)
