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. TBR is a marriage of laser ranging,  
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  
 
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. TBR is matched  
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

Battery Power StatuS IndIcator  
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:  
1. View the object of interest through the monocular.  
2. Depress the POWER button to power up the unit.  
3. Align the reticle over the object being viewed.  
4. Depress the POWER button again – this will cause the laser to activate.  
5. Read the distance as shown in the image field.  
 
CONTINUOUS MEASUREMENT OF A MOVING TARGET / SCAN MODE:  
1. Follow the instructions for “Measuring distance…” as explained previously.  
2. Once the target has been measured, continue to hold down the POWER  
button and follow the object as it moves.  
3. The distance will automatically update as long as the POWER button is  
continuously depressed.  
4. This procedure can also be used to obtain the range of multiple animals  
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.

Deer (yd/m)  
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.

QUICK START MENU  
when you initially push the Power button, the unit is ready for scanning. to  
enter the Quick Set MenutM, press and hold the Mode button for at least 1  
second.  
to manipulate a function, press the Mode button until that function is  
displayed, then use the Power button to change the setting. If this is the last  
function to be changed, you can allow the rangefinder to sit idle for 20 seconds  
which will cause an automatic power-off, saving all selections. If additional  
functions require manipulation, simply press Mode to continue through the  
Quick Set Menu. Pressing and holding Mode for 1 second at any time will  
save all changes, exit the Quick Set Menu, and prepare the rangefinder for  
immediate use.  
Note: Activating certain modes automatically disables other modes. For example  
activating the yards mode will automatically deactivate the meters mode.  
 
FunctIon 1: rIFLe Mode (rFL)  
(rX-750 ModeL onLy)  
F
TBR calculates the equivalent horizontal range  
(level fire range) from which you can determine the  
correct aim for the conditions. For example, if you  
are shooting a .270 caliber, 130 grain bullet at 3,050  
feet per second up a 30° incline at 400 yards, direct  
line of sight, the TBR output will be 372 yards. The  
first step in correctly using TBR is to Practice, Practice,  
Practice. Anytime you handle a firearm or bow, you  
are ultimately responsible for your projectile.  
The inclinometer output is shown beside the LOS. The inclinometer output  
will be disabled when RFL or BOW mode is turned off.  
For rifle users, adjustment or holdover information can also be displayed. The  
available settings are as follows: BAS outputs the equivalent range to use with  
Leupold’s Ballistic Aiming System® reticles or the equivalent horizontal range,  
Hold displays the inches or centimeters to hold over the intended point of  
impact, and MOA displays the minute of angle correction to “dial” into your  
scope.  
11  
 
12  
F
For rifle users, RFL mode is comprised of three TBR  
functions: HOLD, MOA, and BAS. One of these modes  
must be selected. To select the desired function, navigate  
through the Quick Set Menu until RFL is reached (activate  
if necessary). While the RFL icon is highlighted and the  
word “SEt” is shown in the upper display, press and release  
POWER repeatedly to scroll through HOLD, MOA, and BAS  
respectively; press MODE when the desired function is  
displayed. For information regarding BOW settings, please  
see pages 22-23.  
F
BaS displays the equivalent horizontal range, which is based  
upon the ballistics group and sight-in distance you will  
choose in a later mode. this is the range you will want to use  
when shooting, rather than the line of sight distance, which  
may contain gross errors depending upon the shot angle.  
readings will be displayed with equivalent horizontal range.  
the upper display shows the true Ballistic range and the  
lower display shows the line-of-sight distance to the target.  
F
HoLd will display the appropriate amount of holdover to  
use, which is based upon the ballistics group and sight-in  
 
distance you will choose in a later mode. the upper display  
shows whether you should hold Hi or Low, and the number  
of inches or centimeters to be used for proper correction. For  
example, a reading of “Hi, 8” means you should hold 8 inches  
above the intended point of impact if measuring in yards. If  
measuring in meters, you should hold 8 centimeters above the  
intended point of impact. the lower display shows the line-of-  
sight distance to the target.  
F
F
Moa mode will show the minute-of-angle adjustment for  
your target which is based upon the ballistics group and sight-  
in distance you will choose in a later mode. the upper display  
shows whether you should dial the scope’s adjustments up  
or down, and the number of Moa to be used for proper  
correction. For example, a reading of “up, 4” means you  
should dial 4 Moa in the up direction, then aim directly at  
the intended point of impact. the lower display shows the  
line-of-sight distance to the target.

FUNCTION 2: SEVEN RIFLE BALLISTICS GROUPS  
(RX-750 MODEL ONLY)  
tBr includes ballistics settings for seven rifle cartridge groups, which are displayed  
as a, B, c, aB, ac, Bc, and aBc. For example, if your cartridge type is in Group  
a, the displayed reading will account for the shot angle and provide the  
proper distance for holdover purposes (see following chart). you must choose  
one of the seven groups, based on your cartridge and ballistics information.  
tBr performance groups organize load performance in a way that generally  
provides less than 2.5 inches (1/2 minute of angle) of error in aiming out to  
500 yards. the cartridge table shows a common assortment of factory loads  
organized in their tBr performance groups. If you are shooting a similar bullet  
weight and muzzle velocity that falls into the provided selections, you can use  
that mode with full confidence.

For hand loads or any other unique loads not shown in the above list, the table on  
the next page provides a guideline for selecting the appropriate tBr performance  
group. check the ballistic performance of your bullet by consulting your reloading  
manual, ballistics software, or by referring to literature or web sites provided by  
your cartridge manufacturer. you may also visit the Leupold web site at  
www.leupold.com for more assistance in selecting your group. If you have your  
ballistics performance data, select your performance group from the table on the  
next page based on the bullet path at 500 yards. Be sure not to confuse bullet path  
with bullet drop. Bullet path will be related back to your sight-in range whereas  
bullet drop relates only to the total drop of the bullet, regardless of sight-in range.

REMEMBER: Knowing your theoretical bullet path at long ranges does not  
provide a license to take shots beyond ranges at which you have practiced,  
particularly at game animals or where stray shots could hit unintended targets.  
It is your responsibility to have intimate familiarity with the performance of  
your firearm and take full responsibility for the projectile. The RX-750 digital  
laser rangefinder may serve best as a tool for learning performance during  
practice at a secure range so you are ready for that critical shot.

FUNCTION 3: BOW MODE  
(RX-750 MODEL ONLY)  
this mode, when activated, works with tBr to provide the correct ballistics  
range for arrows. to activate, navigate through the Quick Set Menu by pressing  
Mode until the Bow icon is displayed, then use the Power button to turn it  
on/off. Selecting the Bow Mode automatically deactivates the rifle Mode. the  
displayed range represents the ballistically equivalent horizontal distance to  
the target. It incorporates three different groups (a, B, or c) depending on the  
particular arrow drop. you must choose one of the three groups, based on your  
bow and arrow performance.

repeatedly to scroll through the available ballistics groups.  
 
W
only one group can be selected at a time. Selecting a new  
group deactivates all other groups. Most importantly, using  
Bow effectively means to Practice, Practice, Practice. anytime  
you handle a firearm or bow, you are ultimately responsible for  
your projectile. For best results, measure the drop of your arrow  
at 40 yards when using your 20 yard aiming point.  
1. Set up a small target point such as a two-inch circle of paper high on a large, safe  
background, such as a stack of bales backed by a solid backstop. Be sure to allow for  
three feet or more of drop to avoid arrow damage.  
2. Shoot 2 or 3 arrows at the target from 40 yards, using your 20 yard pin on the small  
target.  
3. Measure the distance from the small target to the center of the group of arrows.  
4. Select your TBR bow group from the “Drop from 20 yard pin at 40 yards”  
column above.  
Initial velocity should only be used if an arrow speed chronograph  
measurement has been obtained. Manufacturer’s published data such as IBO  
speed is based on standard draw length and weight that is likely to vary with  
your bow, therefore the actual performance may not be the same.

FUNCTION 7: 3 SELECTABLE RETICLES  
This mode allows you to choose any one of the 3 preloaded reticles as the  
primary aiming point for the RX-600 / 750 digital laser rangefinders. To select  
a reticle, press MODE repeatedly until the current reticle is blinking. Press  
POWER repeatedly to scroll through the available reticles, then press MODE  
when the preferred reticle is shown. The reticle choices are as follows:  
Plus Point™  
Duplex®  
Duplex®  
with Plus Point™  
without Plus Point™  
Plus PointTM: Ideal for varmints  
and other small targets. Small open  
center avoids coverage of very  
small or distant targets.  
Duplex®: Familiar reticle to shooters from riflescopes; draws eye to the center,  
easy to see, does not cover the target in the center where aiming is most critical.  
 
Cleaning/Maintenance  
Blow away dust or debris on lenses, or use a soft lens brush (such as the one  
found on the Leupold LensPen). To remove fingerprints, water spots or tougher  
dirt, use a soft cotton cloth or the cleaning end of the Leupold LensPen. A lens  
tissue with lens cleaning fluid may be used for more stubborn dirt. Always  
apply cleaning fluid to the cleaning cloth, never directly to the lens.  
To insert a new battery, remove battery cover (shown in diagram on page 4) and  
remove exhausted battery. Insert new CR-2 battery, negative terminal  
first, into the battery compartment. Close battery cover.  
To focus the digital laser rangefinder, turn the eyepiece left or right  
(you will feel and hear the clicking of the diopter, indicating a change  
to the focus has been made) until crisp display focus is achieved.  
RX-600 and RX-750 models are weatherproof.  
All models include a lanyard and are equipped with a lanyard attachment  
for added security in the field. All models are also supplied with a small  
instructional supplement in the inside pocket of the included case.

Helpful Hints for Using the Leupold  
RX-600/750 Digital Laser Rangefinders  
HOW DO I ACTIVATE TRUE BALLISTIC RANGE (TBR)?  
Only available in RX-750.  
See Function 1 on page 11. Be sure to select the proper group for bows  
on page 22 or rifles on pages 16-21.  
HOW DO I ACTIVATE SIMPLE LINE OF SIGHT (LOS) RANGE?  
Always on for all RX-600 models.  
For RX-750 model, follow the Quick Set Menu procedure (see page 10)  
.
WHEN I SHOOT BASED ON THE TRUE BALLISTIC RANGE READOUT PROVIDED  
BY THE RANGEFINDER, THE PROjECTILE IS NOT HITTING THE TARGET.  
The first step in correctly using TBR is to Practice, Practice, Practice. Anytime  
you handle a firearm or bow, you are ultimately responsible for your  
projectile. Be certain that if you’re shooting a bow that “BOW” is turned on.  
Be certain that if you’re shooting a rifle that “RFL” is turned on.  
Be certain you selected the correct ballistics groups (see page 22 for bows  
or pages 16-21 for rifles). It is imperative that a rifle be sighted-in at the  
recommended range.  
 
For rifles, ballistics performance of firearms and ammunition may vary from  
manufacturers published information.  
RANGEFINDER DOES NOT PROVIDE RANGE.  
Make sure that the POWER button is being depressed (as opposed to  
MODE button)  
Make sure that nothing, such as your hand or finger, is blocking the  
lenses — as this could interfere with the emission and reception of the  
laser pulses  
Make sure unit is held steadily while depressing the POWER button  
When using BOW mode, it is important to note that TBR returns are  
limited to 60 yards; returns greater than 60 yards will be displayed in the  
LOS display; 800 yards for rifles  
Make sure the target is at least 5 yards away  
HOW DO I ACTIVATE THE INCLINOMETER READOUT?  
RX-750 Models: RFL or BOW must be activated for the angle of inclination to  
display (see page 11 for rifles or page 22 for bows).  
NOTE: The inclinometer is only available on the RX-750 model.
