bullet. TBR/W is a marriage of laser ranging, an inclinometer, and an advanced
computerized ballistics program. The result is distance measurements accurate
to less than 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
or horizontal 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. For rifle shooters, the Leupold team has added to the TBR
functionality by adding wind hold calculations that will provide a fixed 10 MPH
full wind value. Other features that are provided for firearms are outputs that
display either MOA adjustments, or inches / centimeters / mils 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 each of twenty-
five firearm ballistics groups or archery ballistics, allowing use with most popular
firearms and bows.
HOW THE RX -1200i WORKS
The RX -1200 i is a top-quality 6x22mm monocular that incorporates 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 800 yards, an inanimate
object from 5 yards to 900 yards, and a reflective target from 5 yards to 1,200
yards. It emits 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

The Leupold RX -1200 i 6x22mm rangefinder does employ an eye safe FDA Class 1
laser in its operation. Outside of the United States, the IEC is the governing body
over laser products and has classified the RX-1200ias Class 3R. 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 RX-1200 i 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 -1200 i is designed to prohibit accessing any
other external power supply

READING THE INTERNAL DISPLAY
The Organic Light Emitting Diode (OLED) display reflected into the optical path
can be manually switched between ranging modes, as measured in meters
(M) or yards (YD), or used to obtain distance while simultaneously viewing
the target. (The RX -1200ican also simply be used as a 6x monocular without
activating the OLED.)
INTERNAL DISPLAY AS SEEN THROUGH THE RX-1200iTBR/WWHEN THE
POWER BUTTON IS DEPRESSED
– Indicates the distance to the target
in either yards or meters. RX-1200iTBR/W
Models have the additional capability of
displaying the True Ballistic Range to the target,
or shot placement information.

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 – 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-1200 i
Measurement of distance with the RX -1200 i 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.

8
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
button and follow the object as it moves.
2. The distance will automatically update as long as the POWER button is
continuously depressed.
3. 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 taken 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.
The ranging accuracy of all Leupold RX -1200 i Series rangefinders is ± 0.5 yards/
meters at distances less than 125 yards/meters, while the accuracy beyond 125
yards/meters is ± 2 yards. The maximum range of the unit depends on the
reflectivity of the target and atmospheric conditions.

9
Following is a reference table listing the ranges of all RX-1200imodels 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. The
sun generates infrared energy that can degrade ranging performance in bright
conditions or when ranging towards the sun.

FUNCTION 1: TBR, BOW OR LOS
To activate TBR, BOW, or LOS, activate the RX-1200iby pressing the POWER
button, then press and release the MODE button to enter the menu. While
“Out Put” is shown in the display, press and release the POWER button
to rotate through TBR, BOW, and LOS modes. Once the desired mode is
displayed, press the MODE button for >1 and release.
The inclinometer output is shown beside the battery status indicator.
NOTE: LOS is always active on non-TBR models.
TBR FOR RIFLE USERS (TBR/W MODELS ONLY)
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 367 yards. The

14
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.
For rifle users, scope adjustment or holdover information can also be
displayed. The available settings are as follows: BAS outputs the equivalent
horizontal range, HOLD displays the inches or centimeters (depending
on unit of measure selected) to holdover the intended point of impact,
MIL displays the number of milliradians to holdover the intended point of
impact and MOA displays the minute of angle correction.
TBR for rifle settings is effective to 800 yards for most
cartridges. For rifle users, TBR mode is comprised of five
functions: BAS, HOLD, MIL, MOA and TRIG. One of these
modes must be selected. To select the desired function,
rotate through the output until TBR is reached (activate if
necessary). While the TBR icon is highlighted and the word “SEt” is shown
in the upper display, pressing POWER repeatedly will scroll through BAS,
HOLD, MIL, MOA and TRIG respectively; press MODE when the desired
function is displayed. For information regarding BOW settings, please see
page 17.

15
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 in the lower portion of the display.
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 the
line of sight distance to the target. The lower display will
briefly show whether you should hold high or low, then the
appropriate number of inches or centimeters to hold over or
under. In the example to the right, the line of sight distance
is 484 yards, and the lower display indicates that you should
hold 51.4 inches above your intended point of impact. If the
RX-1200iTBR/W is set to range in meters, the appropriate holdover would be
shown in centimeters.

16
MIL will display the appropriate amount of holdover in
milliradians to use, which is based upon the ballistics group
and sight-in distance you will choose in a later mode. The
upper display shows the line of sight distance to the target.
The lower display will briefly show whether you should hold
high or low, then the appropriate number of mils to hold
over or under. In the example to the right, the line of sight
distance is 484 yards, and the lower display indicates that you
should hold 2.9 mils above your intended point of impact.
Holdover values will be displayed in mils for both yards and
meters modes.
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 the line of sight distance to the target. The lower
display will briefly show whether you should dial the scope
in the up or down direction, then the appropriate number
of MOA adjust. In the example to the right, the line of sight
distance is 484 yards, and the lower display indicates that you
should dial the scope up 10.1 MOA to account for bullet drop.

17
Scope corrections will be displayed in MOA for both yards and meters
modes.
TRIG, a function that is included to support engineers and
sportsmen, displays the true horizontal range and true
vertical range, which is based upon trigonometry using
angle and line of sight distance. Line of sight distance
(LOS) readings will be displayed in the lower portion of
the display. The upper display will briefly show the true
horizontal distance (cosine) then the absolute value of the
true vertical distance (sine). Have you ever wondered if
that leaning tree would hit your home or tent if it fell?
Measure the height by obtaining the true vertical distance
and then measure the distance from your house or tent to the tree.
BOW (TBR/W MODELS ONLY)
This mode, when activated, works with TBR to provide the
equivalent horizontal range (level fire range) for arrows.
The displayed range represents the ballistically equivalent
horizontal distance to the target if the target is 125 yards
or less. If the target is farther than 125 yards (114 meters),
the LOS icon will flash while BOW remains displayed, and
