SAFETY PRECAUTIONS (Laser)

The Leica Rangemaster uses an invisible laser beam.
Be sure to observe the following:

WARNING

• Use of controls or adjustments or performance of
procedures other than those specified herein may
result in hazardous radiation exposure
• When you see the display through the eyepiece,
please be aware that the product is active and
emitting an invisible laser and the laser aperture
should not be pointed toward anyone
• Do not take the product apart or modify the product
in any way to expose internal electronics that might
cause damage or electric shock
• Do not depress any button while aiming at a human
eye or while looking into the optics from the objective side
• Do not leave the Leica Rangemaster within the
reach of small children

CAUTION

• Do not aim at the eye.
• Do not point the laser at people.
• Do not operate the unit with other additional optical
elements, such as lenses or binoculars. Using an
optical instrument together with the Leica Rangemaster increases the danger of damaging the eyes.
• When not measuring, please keep your fingers away
from any button to avoid accidentally emitting the
laser beam.
• When not in use for an extended period, please
remove the battery from the body

• Do not disassemble/remodel/repair the Leica
Rangemaster. The emitting laser may be harmful to
your health. A product that has been disassembled/
remodeled/repaired is not guaranteed by the
manufacturer.
• If the Leica Rangemaster’s body cover is damaged,
or if it emits a strange sound due to dropping or
some other cause, remove the battery immediately
and stop using

FOREWORD

We wish you a great deal of enjoyment and every
success with your new Leica Rangemaster. This
rangefinder emits invisible infrared impulses that are
not harmful to the viewer’s eyes and uses an integrated
microprocessor to calculate the distance to an object
from the reflected signal component. In addition, it
registers ambient and situational parameters. With
these – and the measured distance – it calculates the
respective holdover values for different, selectable
ballistic curves and displays them. It features an
outstanding scope with 7x magnification, ensuring a
reliable bearing even under difficult conditions. Plus,
the Leica Rangemaster is easy to handle and operate.
To ensure that you get the best out of this high-quality
and versatile laser rangefinder, we recommend reading
these instructions first.

Disposal of electrical and electronic
equipment

(Applies within the EU, and for other European countries with segregated waste
collection systems)
This device contains electrical and/or electronic
components and must therefore not be disposed
of in general household waste! Instead, it should be
disposed of at a recycling collection point provided
by the local authority. This costs you nothing. If the
device contains standard or rechargeable batteries,
these must be removed first and also be disposed of
in line with relevant regulations (for details, refer to the
instructions of your device) Further information on this
issue is available from your local administration, your
local waste collection company, or in the store where
you purchased this device.

SCOPE OF DELIVERY – Rangefinder

– 1 lithium battery 3V, type CR 2

– Carrying strap

– microSD memory card 8 GB

– microSD card adapter

– Cordura case

– Guarantee Card

– Test certificate

Warning note
As with all binoculars, avoid looking directly at
bright light sources with your Leica Range
-master in order to avoid eye damage.

ATTACHING THE CARRYING STRAP

Feed the small loop on the carrying strap through the
eyelet 4 on the housing of the Leica Rangemaster.
Then thread the end of the strap through the small loop
and pull tight, so that the resulting loop is securely
around the eyelet on the housing.

CHANGING THE BATTERY

The Leica Rangemaster is powered by a cylindrical
3 Volt lithium cell (e.g. Duracell DL CR2, Ucar CR2,
Varta CR2, or other CR2 types).
1. Open the cover 6 on the battery compartment 7
by turning it counter-clockwise.
2. Insert the battery so that the positive contact goes
in fi rst (as shown by the markings in the battery
compartment).
3. Close the cover again by turning it clockwise.

Notes:
• Cold conditions impair the battery performance. At
low temperatures the Leica Rangemaster should be
kept as close to the body as possible and a new
battery should be fi tted.
• If the Leica Rangemaster will not be used for a long
period, the battery should be removed.
• Batteries should be stored in a cool dry place.

Attention:
• Batteries should never be put in a fi re, heated,
recharged, taken to pieces or broken apart.
• Used batteries may not be disposed of as normal,
household waste as they contain toxic materials that
are harmful to the environment. To ensure that they
are properly recycled, they should be returned to
the dealer or disposed of as special waste (at a
collection point).

BATTERY CHARGE LEVEL

A used battery is indicated by a fl ashing measured
value and reticule display. Once the display starts
fl ashing, at least another 100 measurements are
possible, with a gradually reducing range.

USE WITH AND WITHOUT GLASSES

Users who do not wear glasses can leave the rubber
eyecup 3 folded up (Figure A, as supplied). This
position gives the correct distance between the Leica
Rangemaster and the eye. When using the Leica
Rangemaster with glasses, the rubber eyecup should
be folded down (Figure B).

DIOPTER COMPENSATION

Diopter compensation enables you to adjust the
sharpness of the reticule to the optimum value for you.
Simply aim the Leica Rangemaster at a distant object
and adjust the reticule until it has optimum sharpness
by turning the eyecup 3. The reticule appears when
you press the main button 2. You can read the set
value on the “+” or “-” scale 3a on the eyecup. Diopter
compensation is available for vision defects of up to ±
3.5 diopters.

BASIC INFORMATION ON MENU CONTROL

The main menu is made up of four menu items:
– Meter/Yard Display (EU.US)
– Ballistic curve (bALL)
– Zeroing distance (SId)
– ballistic output formats (AbC)
Details of the individual functions can be found in the
relevant sections.

Generally:
Both the main menu and the setting options are set up
as a continuous loop – i.e. all items/settings are
accessible by continually pressing the button.

SETTING THE UNIT OF MEASURE

The Leica Rangemaster can be set to metric or imperial
units of measure, i.e. for distance/temperature/
atmospheric pressure either meters/Celsius/millibar
or yards/Fahrenheit/InHg (Inches of Mercury). This
setting also determines the details of the holdover, the
ballistic curves and the zeroing distance.
1. Press and hold the secondary button 1 (≥ 3 s).
• EU.US appears (flashing).
2. Press the main button 2 to select the desired unit
of measure.
US = for display in yards
EU = for display in meters

Note:
The current setting can always be seen in the display:
M (for meters) or Y (for yards) appears in addition to
the digits display.
3. Save your setting by briefly pressing the secondary button (< 2 s).
• The saved setting is initially lit continuously as
confirmation, then the display switches to the
next item in the menu (ballistics curve „bALL“)
and then disappears if no further settings have
been made

DISTANCE MEASUREMENT

To measure the distance to an object, you must aim
directly at it. To do this, proceed as follows:
1. Press the main button 2.
This switches on the device.
• The reticule appears.
When you release the main button, the reticule remains
lit for around another 6 seconds. If you hold it down,
the reticule remains lit continuously.
2. Aim at the object while the reticule is lit.
3. Press the main button again.
a. The reticule disappears briefl y during the measurement.
b. The measured value is displayed.
As long as the reticule remains lit, you can carry out
another measurement at any time by pressing the main
button again.
– – – appears, if
– the distance to the object is less than 10 yards,
or
– the range is exceeded, or
– the object is not suffi ciently refl ective.
When the display disappears, the Leica Rangemaster
shuts down automatically

SCAN MODE

The Leica Rangemaster can also be used for continuous measurements (scan mode):
Press and hold the main button 2 at the 2nd press.
After around 2.5 seconds, the device switches to scan
mode and then carries out continuous measurements.
This can be seen by a change in the display. Around
every 0.5 seconds, a new measured value is shown.
Scan mode is particularly useful for measuring the
range to small or moving targets.
Notes:
• In scan mode, the AbC compensation value (see
p. 45) is displayed after the last measurement.
• Because of the continuous measurements, power
consumption is greater in scan mode than for single
measurements.

MEASURING RANGE AND ACCURACY

The maximum range is achieved with highly reflective
target objects and a visual range of sight of around
11000 yards. Long ranges can be reliably measured /
achieved by holding the Leica Rangemaster very
steadily and/or placing it on a solid surface. The
measuring range is influenced by the following factors:

In sunlight and with good vision, the following ranges
and accuracies can be achieved:

Note:
Distances below 200 m/219 yds are shown with an
accuracy of one decimal place, e. g. 164.5

INDICATION OF ATMOSPHERIC CONDITIONS

To accurately calculate the impact point (see following
section), the Leica Rangemaster also determines three
crucial pieces of additional information when measuring the range:
– the inclination of the unit
– temperature
– atmospheric pressure
You can display the relevant values at any time.
Press the secondary button 1 briefl y 1x.
• The reticule appears briefl y (if distance measurement was not previously activated) and then the
following items appear in succession for around 2 s
each instead of the range:
– inclination (indicated by an additional angle
symbol)
– temperature
– atmospheric pressure
Note:
If the housing of the Leica Rangemaster initially has a
signifi cantly diff erent temperature than the surroundings, for example when moving from inside to outside,
it can take up to 30 minutes before the internal sensor
can display the correct ambient temperature again.

DETERMINING THE BALLISTIC CURVE

For the precise determination of the impact point
correction, the Leica Rangemaster includes the bullet
trajectory on the basis of the used caliber, as well as
the bullet type and weight in the calculation. This
includes the adjustment of the calculation of the
equivalent horizontal distance (EHr, see p. 51) of the
holdover (HOLd, see p. 22 ) or the sight adjustment
(1/1-4/1-3/10/5, see p. 52) on request. Twelve
different ballistic curves are available for adaptation to
the equipment you are using. From the appropriate
table in the appendix, find the ballistic curve that is
closest to the bullet drop specified by the ammunition
manufacturer. Make sure you choose the appropriate
down range distance.

Example:

The rifle scope is zeroed to 100 meters, which means
that Table 1 is applicable. The specified impact point
for the ammunition used is -15.0 cm at 200 m. In the
corresponding column, this is closest to the value 14.5
cm in row EU7 – this is therefore the appropriate
ballistic curve.

Note:

When using the Leica Rangemaster’s ballistic function
at distances longer than 330 m/yds and/or other
ammunition types that are not covered by the internal
settings of the device, we recommend to either determine the ballistic data of your ammunition through
practical testing to choose the appropriate curve, or to
determine it with the Leica ballistics calculator and to
transfer it by memory card to the device.

Setting the ballistic curve

Start with step 1 if you have not previously opened the
menu control, or with step 3 if you have just set the
unit of measure and bAll is still flashing in the display.
1. Press and hold the secondary button 1 (≥ 3 s).
• EU.US appears.
2. Press the secondary button briefly (< 2 s) once.
• The display switches to the ballistic curves
bALL.
3. Press the main button 2.
• The display switches to
– EU1 or
– US1
Note:
When a memory card is inserted (see p. ??),
CArd appears before EU1 / US1.
4. By pressing the main button repeatedly, select the
desired ballistic curve, i.e.
– EU1 to EU12 or US1 to US12, or
– OFF, if you want to have a distance display
without point of impact settings display (AbC,
see p. 51 ff).
5. Save your setting by briefly pressing the secondary button.
• The saved setting is initially lit continuously for
4 s as confirmation, then the display changes
first to the zeroing distance setting (SId) and
then disappears.
If a ballistic curve is set, after each distance measurement the range value is first displayed for 2 s, then the
calculated correction value for 6 s.

SETTING OF ZEROING DISTANCE (SId)

Start with step 1 if you have not previously opened the
menu control, or with step 3 if you have just set the
unit of measure and SId is still flashing in the display.
1. Press and hold the secondary button 1 (≥ 3 s).
EU.US appears.
2. Press the secondary button briefly (< 2 s) once.
The display switches from bALL to SId.
3. By pressing the main button 2 repeatedly, select
the desired down range distance.
– 100 [m],
– 200 [m] or
– GEE [m] or
– 100 [y] or
– 200 [y] or
– 300 [y].
4. Save your setting by briefly pressing the secondary button.
• The saved setting is initially lit continuously for
4 s as confirmation, then the display switches
to AbC and then disappears.

BALLISTIC OUTPUT FORMATS (AbCTM)

The advanced ballistic compensation (AbC) on the Leica
Rangemaster allows you to display one of the following
three ballistic values after the measured range if
required:
– the equivalent horizontal range (EHr)
– the corresponding holdover (HOLd)
– the number of clicks required on the rapid reticle
adjustment (MOA/clicks)
Both the displayed holdover and EHr values factor in:
a. the measured range to the target
b. the angle of inclination of the weapon
c. the set ballistic curve
d. the measured temperature and atmospheric
pressure values
e. the set zeroing distance

Notes:
• Calculation of the specified values is based on the
currently set ballistic curve, i.e. the curve must be
selected first (see p. 48).
• For safety reasons, ballistic output values are only
specified up to a range of 800 m/yds. The actual
measured range is also specified.

Important:
• Please note that particularly at long ranges, the
influence of all relevant ballistic influencing factors
is greatly increased and considerable variations can
occur. The ballistic values displayed should therefore only be viewed as a guideline.
• Regardless of whether this information is used, you
are responsible for assessing the relevant hunting
situation.

SETTINGS AND SELECTION OF BALLISTIC
OUTPUT FORMATS

Start with step 1 if you have not previously opened the
menu control, or with step 3 if you have just set the
down range distance and ABC is still flashing in the
display.
1. Press and hold the secondary button 1 (≥ 3 s).
• EUUS appears.
2. Press the secondary button briefly (< 2 s) once.
• The display switches from bALL and SId to AbC.
•
3. By pressing the main button 2 repeatedly, the
desired ballistic setting is selected.
– EHr or
– HOLd or
– 1 (1 MOA), (display in decimal)
– 1-4 (1⁄4 MOA) or
– 1-3 (1⁄3 MOA) or
– 10 mm or
– 5 mm.
4. Save your setting by briefly pressing the secondary button.
• The saved setting is initially lit continuously for
4 s as confirmation, then the display disappears.

EQUIVALENT HORIZONTAL RANGE (EHr)

Shots at targets at a higher or lower elevation are
subject changed ballistic conditions. Therefore, they
require knowledge of the equivalent horizontal range,
which is relevant for hunting. Knowledge of the EHr is
important when using ballistic reticles, for example. EHr
values are indicated by the additional display .

Note:
Horizontal EHr measurements can also result in values
that differ from the „straight line“ measured range, for
example if the temperature and/or the atmospheric
pressure vary from the normal values.

HOLDOVER (HOLd)

Holdover is defined as the point that you aim at with
the weapon instead of the actual target point to
compensate for the variation caused by the trajectory
of the bullet (e.g. when using classic hunting reticles).
By displaying the holdover, the Leica Rangemaster can
provide valuable support in achieving the most accurate shots possible when hunting. In addition to the
range, the calculation is based on the general conditions discussed in the previous section and the ballistic
curve you have selected.

Note:
The holdover/elevation is always shown with reference
to the range to the target.
Example: If 300m 30 is displayed, you would have to aim
30 cm higher on the object than without correction.

IMPACT POINT CORRECTION USING ELEVATION ADJUSTMENT (Click/MoA adjustment)

Variations in the point of impact can be compensated
by adjusting the reticle on your riflescope accordingly.
Based on the bullet trajectory and the zeroin distance,
the Leica Rangemaster can show you the required
adjustment, i.e. the relevant number of clicks. For
different elevations, you can specify whether the click
levels will be
– based on the international standard MOA (minutes of angle) graduation, or
– displayed in 5 or 10 millimeter increments.

Displaying and checking the set ballistic
parameters

If you want to check your settings, you can display the
values at any time.
Press the secondary button 1 briefly 2x.
• Below the reticule (instead of the range, if this was
previously displayed), the following will appear in
turn for around 2 s each:
– the set ballistic curve
– the set zeroing distance
– the set ballistic output value
Note:
When all ballistic functions are deactivated (bALL =
OFF), only the OFF setting is displayed.

USE OF ANY BALLISTIC CURVES

If the intended combination of weapon and ammunition
is not already covered by one of the programmed
ballistic curves EU1 / US1-EU12 / US12, you can also use
your own, individual ballistic curves with the Leica
Rangemaster.
This is done in four steps:

A. Insertion of the Micro-SD memory card
in a card reader via the supplied SD
card adapter
(connected to a computer)

B. Calculation of the desired ballistic
curve and transfer to the Micro-SD
memory card
Access to the Leica Ballistic Calculator as well as
the respective entry mask can be found on the
Leica Ballistic Program page under
https://de.leica-camera.com/Sportoptik/Leica-Jagdoptik/Leica-Ballistikprogramm

C. Inserting / Removing the memory card
into / from the Leica Rangemaster

D. Opening the ballistic curve from the
memory card

If a memory card with a ballistic curve is inserted
into the Leica Rangemaster, it can be selected just
as described under “Setting the ballistic curve” on
p. 49.
• After pressing the main button 2 CArd appears
fi rst in this case. If a distance measurement is
subsequently performed, the following warning
messages may appear:
– Err1 if the bALL menu was selected, but the
memory card is removed, defect or nonreadable. In this case, CArd also disappears.
– Err2 if there is no ballistic curve on the
memory card.
– Err3 if the ballistic curve on the memory card
does not contain correct data. The following
procedure corresponds to the one for the
programmed ballistic curves.
Cntinued on next page.

Notes:
• Do not touch the memory card contacts.
• If the memory card cannot be inserted, check that it
is aligned correctly.
• The range of available microSD memory cards is too
large for Leica Camera AG to be able to completely
test all available types for compatibility and quality.
Although no damage to the rangefinder or the card
is generally expected, because some so-called “no
name” cards may not fully comply with the microSD
standards Leica Camera AG cannot provide any
guarantee of function.
• For safety reasons, that is to avoid confusion, only
one ballistic curve can be saved on a card. For the
same reason, a file will not be recognized if you
change its name.
• When using ballistic curves from the memory card,
distances of up to 925 m/1000 y will be displayed.
• Even though a memory card is inserted, one of the
programmed ballistic curves can be selected at any
time. Hence, please always check your settings.

TROUBLESHOOTING

TECHNICAL DATA

CARE/CLEANING

Your Leica Rangemaster requires no special care.
Coarse particles of dirt such as sand should be
removed with a hair brush or blown away. Fingerprints
or similar on objective and eyepiece lenses can be
pre-cleaned with a damp cloth and then wiped off with
a soft, clean chamois or dust-free cloth.
Important:

Do not exert excessive pressure, even when wiping
very dirty lens surfaces. Although the coating is highly
abrasion-resistant, it can nevertheless be damaged by
sand or salt crystals.
The housing should be cleaned only using a damp
cloth. There is a risk of static charges if dry cloths are
used. Alcohol and other chemical solutions must not
be used to clean the lens surfaces or the housing. In
addition to the designation by type, each Leica Rangemaster has an individual serial number. Please note this
number in your documents as a safety measure.
Attention:
Never open the unit.
