Introduction
Congratulations! You have purchased a Leupold® RX-600 / RX-750 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 rangefinder. To ensure top performance
for the life of the product, please read these instructions before operating your
RX-600 / RX-750.
Your new Leupold RX rangefinder is a revolutionary, range-finding device
that incorporates advanced digital electronics with state-of-the-art ballistics
algorithms. RX-600 / RX-750 features include inclinometer, multiple reticle
options, and Last Target Mode. However the truly innovative and unique
feature is True Ballistic Range® (TBR), which is available on the RX -750 model.
TBR 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.
an inclinometer, and an advanced computerized ballistics program. The result
is distance measurements accurate within a yard, no matter the angle at which
the laser is fired.
Bullets and arrows travel in a ballistic arc, yet conventional
TBR is a marriage of laser ranging,
rangefinders only provide a linear distance to your target. TBR delivers the
ballistic equivalent range to the target, accounting for the effects of inclines or
declines 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. TBR eliminates any potentially significant
error, and provides a precise range for your aiming calculations.
to seven rifle ballistics groups and three archery ballistics groups, allowing use
with most popular firearms and bows.

HOW THE RX-600 / RX-750 WORKS
The RX-600 and RX-750 are top-quality 6x22mm monoculars that incorporate the
additional benefit of a state-of-the-art laser rangefinder capable of measuring
the distance of a deer-sized animal from 5 yards to 400 yards (RX-600), 500 yards
(RX-750), an inanimate object from 5 yards to 500 yards (RX-600), 600 yards (RX-
750), and a reflective target from 5 yards to 600 yards (RX-600), 750 yards (RX-
750). The rangefinders emit a series of invisible, infrared energy pulses that are
reflected off the selected target back to the optical unit. State-of-the-art circuitry
and precision computing circuits are used to calculate the distance by measuring
the time it takes for each pulse to travel from the RX-600 / RX-750 to the object
and back.

Safety and Operation Precautions
The Leupold RX-600 and RX-750 6x22mm rangefinders employ an eye safe
FDA Class 1 and CE Class 3A laser in their operation. Even so, there are a few
precautions that are important to remember:
Do not depress the POWER button while aiming at a human eye or while •
looking into the optics from the objective side
Do not leave the rangefinders within the reach of small children•
Do not take the product apart as it has a self-protection device in the •
electronic control module and may cause an electric shock
Do not attempt to use any power source other than a CR2 battery •
(or equivalent) — the RX-600 and RX-750 rangefinders are designed to
prohibit accessing any other external power supply

BAT TERY P OWER STATUS INDI C ATOR
To determine your battery’s power level, look for the following indicators:
FULL – A full battery bar indicates your battery is at or near peak capacity.
HALF – A half-full bar indicates your battery has reached half-capacity.
LOW – If the battery bar is empty, yet there is still data displayed above the bar, the
battery is nearing the end of its life and should be replaced.
NO POWER – If the battery bar is empty, and there is no data displayed above the
bar, your battery is dead and you must replace it. The battery status bar will flash
and the unit will shut down when no power remains.
MEASURING DISTANCE WITH THE RX-600 / 750
Measurement of distance with the RX-600 / 750 is a very simple operation:
View the object of interest through the monocular.1.
Depress the POWER button to power up the unit.2.
Align the reticle over the object being viewed.3.
Depress the POWER button again – this will cause the laser to activate.4.
Read the distance as shown in the image field.5.
CONTINUOUS MEASUREMENT OF A MOVING TARGET / SCAN MODE:
Follow the instructions for “Measuring distance…” as explained previously.1.
Once the target has been measured, continue to hold down the POWER 2.
button and follow the object as it moves.
The distance will automatically update as long as the POWER button is 3.
continuously depressed.
This procedure can also be used to obtain the range of multiple animals 4.
or objects; simply move the reticle from one target to another while
holding down the POWER button.
CLEARING THE LAST DISTANCE OBTAINED:
The last range reading does not need to be cleared before reading another
object’s distance. For that reason, there is no reset button. Simply aim at the
new object using the reticle, depress the POWER button and hold until the new
range reading is displayed.

Following is a reference table listing the ranges of the various models under
different conditions:
CONDITION RX-600 RX-750
Reflec tive Target (yd /m)
Trees (yd /m)
Deer (y d/m)
MAXIMUM RANGE
600/550 750/685
500/455 60 0/550
400/365 50 0/455
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. The
sun generates infrared energy that can degrade ranging performance in bright
conditions or when ranging towards the sun.
