Foreword

Dear Customer,

All over the world, „Leica“ is synonymous with top
quality precision engineering with extreme reliability
and a long life.
We wish you a great deal of enjoyment and success
with your new LEICA RANGEMASTER CRF 1600.
This range finder emits invisible infrared impulses
that are not harmful to the eyes and uses an inte­grated microprocessor to calculate the distance to
an object from the reflected signal component. In
addition, it detects environmental and usage condi­tions, which it combines with the measured range to
determine and indicate corrections to the holdover
to obtain different selectable ballistic curves.
It features an outstanding scope with 7x magnifica­tion, which enables a reliable bearing even under
difficult conditions, and is easy to operate and func­tional.

To ensure that you get the best out of this high-qua­lity and versatile laser range finder, we recommend
reading these instructions first.

Disposal of electrical and
electronic equipment

(Applies within the EC, and for other
European countries with segregated
waste collection systems)

This device contains electrical and/or electronic
components and should 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 itself contains removable batteries or rechar­geable batteries, these should first be removed and,
if necessary, properly disposed of (refer to the speci­fications in the manual for your device).
More information on this subject can be obtained
from your local authority, your disposal company or
the shop where you bought this product.

Attaching the carrying cord

Feed the small loop on the carrying cord through
the eyelet (4) on the housing of the LEICA RANGE­MASTER CRF 1600. Then thread the end of the cord
through the small loop and pull tight, so that the
resulting loop is securely around the eyelet on the
housing.

Inserting and changing the battery

The LEICA RANGEMASTER CRF 1600 is powered
by a 3 Volt lithium round 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 anticlockwise.

2. Insert the battery so that the positive contact
goes in first (as shown by the markings in the bat­tery compartment).

3. Close the cover again by turning it clockwise.

22

Notes:

• Cold conditions impair the battery performance.
At low temperatures the LEICA RANGEMASTER
CRF 1600 should be kept as close to the body as
possible and a new battery should be installed.

• If the LEICA RANGEMASTER CRF 1600 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 fire, 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 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 weak battery is indicated by a flashing measured
value and reticule display. Once the display starts
flashing, at least another 100 measurements are
possible, with a gradually reducing range.

23

A B C

Use with and without glasses

Users who do not wear glasses can leave the rubber
eyepiece cup (3) raised (Figure A, as supplied).
This position gives the correct distance between the
LEICA RANGEMASTER CRF 1600 and the eye.
When using with glasses, the rubber eyepiece cup
should be pressed down (Figure B).

Dioptric compensation

Dioptric compensation enables you to adjust the
sharpness of the reticule to the optimum value for
you. Simply aim the LEICA RANGEMASTER CRF 1600
at a distance object and adjust the reticule until it has
optimum sharpness by turning the rubber eyepiece
cup (3). The reticule appears when you press the
main button (1). You can read the set value on the “+”
or “-” scale (3b) on the rubber eyepiece cup. Dioptric
compensation is available for vision defects of up to
±3.5 diopters.

24

Setting the unit of measure

The LEICA RANGEMASTER CRF 1600 can be set to
metric units or the Imperial units more commonly
used in the USA, i.e. either meters/Celsius/millibars
or yards/Fahrenheit/PSI (pounds per square inch) for
distance/temperature/atmospheric pressure respec­tively. This setting also determines the holdover display
(in centimeters or inches) and the available ballistic
curves (see page 148).

Note:

For all settings: The relevant displays disappear 3
seconds after you last press one of the two buttons.
The previously saved settings/values are retained.

Note:

The current setting can always be seen in the display
– if metric values are selected, a dot appears to the
bottom right of the reticule.

6. Save your setting by briefly pressing the main button.

• The saved setting and the reticule light up con­tinuously for 2 seconds for confirmation and
then disappear.

25

Range finding

To measure the distance to an object, you must aim
directly at it. To do this, activate the reticule by press­ing the main button (1) once.
When you release the button, the reticule remains lit
for around another 8 seconds. With the button held
down, the reticule remains lit continuously. While it is
lit, aim at the object and press the main button again
to measure the range, and the measured value is then
displayed. The reticule disappears briefly during the
measurement. As long as the reticule remains lit, you
can carry out another measurement at any time by
pressing the main button again.

If the distance to the object is less than 10 meters,
the measuring range is exceeded or the object is not
sufficiently reflective, - - - appears in the display.
When the display disappears, the LEICA RANGEMAS­TER CRF 1600 shuts down automatically.

Scan mode

The LEICA RANGEMASTER CRF 1600 can also be used
for continuous measurements: Holding down the main
button (1) the second time it is pressed switches the
unit to scan mode after around 2.5s and it then per­forms continuous measurements. This can be seen by
a change in the display: Around every 1 second, a new
measured value is shown. Scan mode is particularly use­ful for measuring the range to small or moving targets.

Hinweise:

• In scan mode the ballistic correction value (see
page 31) is only displayed after the last measure­ment, not before.

• Because of the continuous measurements, power

consumption is greater in scan mode than for
single measurements.

26

Operating range and accuracy

The measuring accuracy of the LEICA RANGEMASTER
CRF 1600 is up to ±1 meter. The maximum range
is achieved with well reflecting target objects and a
visual range of around 10km. The measuring range is
influenced by the following factors:

Range Longer Lower
Color White Black
Angle to Perpendicular Acute

lens
Object size Large Small
Sunlight Low (cloudy) High (midday sun)
Atmospheric Clear Hazy

conditions
Object structure Homogeneous Non-homogeneous

(wall of building) (bush, tree)

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

Range Approx. 10 m to 1460 m
Accuracy Approx. ± 1yd up to 500 yd

Approx. ± 2 m up to 100 m
Approx. ± 0,5 % over 1000 m

27

Display of atmospheric conditions

For accurate calculation of the impact point (see
following section), the LEICA RANGEMASTER CRF
1600 also determines three of the most important
general conditions when measuring the range: the
inclination of the unit, the temperature and the
atmospheric pressure. You can display the relevant
values at any time.
To do this, briefly press the secondary button when
the reticule or the range is displayed.

• Below the reticule (or instead of the range), the
following will appear in turn for around 2 seconds
each:
– Angle of inclination
– Temperature
– Atmospheric pressure

Holdover display

If required, the LEICA RANGEMASTER CRF 1600 will
display the corresponding holdover after the mea­sured range. When used for hunting/shooting, this
enables the unit to provide valuable information for
the shooter in firing the most accurate shot possi­ble. In addition to the range, the calculation is based
on the general conditions discussed in the previous
section and the ballistic curve you have specified.

Notes:

• The displayed holdover value / correction value
(see also page 31) is always shown in cm for a
range of 100m or in inches for 100yards.

The correction value for the range actually measu-

red is automatically converted to 100m/100 yds.
The major advantage of this is that the correction
value can be set directly on the riflescope, i.e. with­out elaborate prior conversion.

28

Example:

If is displayed and you use a riflescope
on which an adjustment by one graduation (click)
results in a correction of 1cm/100m, you can
make the required correction easily by turning by 7
graduations upwards. The same applies for ballistic
reticles.

• Holdover corrections for ranges above 500m are
not shown due to the overall uncertainty factors.

Important

The holdover display is explicitly intended as a guide.
Regardless of whether you use this information, the
final assessment of the hunting situation and firing of
an expert shot is, as always, your responsibility alone.

Determining the ballistic curve

For precision adjustment of the holdover calculation
to different calibers, bullet types and weights, you can
choose from 12 different ballistic curves. These differ
in terms of the zeroing range to which the riflescope
on the weapon is adjusted. In the appendix, you will
find five corresponding tables (see page 146), three
for zeroing ranges in meters and two in yards. In the
table corresponding to the set zeroing range, find the
ballistic curve that is the closes to the impact point
data provided by the ammunition manufacturer.

Example:

The rifle is adjusted to 100 meters, therefore Table
1 is applicable. Meanwhile, -15.0 cm at 200 m is
specified as the impact point for the ammunition
used. In the corresponding column, this is close to
the value 14.5 cm in row EU7 – this is therefore the
appropriate ballistic curve.

6. Save your setting by briefly pressing the main button.

• The saved setting is lit continuously for 2s as
confirmation and then disappears.

If a ballistic curve is set, after each range measure­ment the range value is first displayed for 2s, then
the calculated holdover for 6s. This display is made
up of a figure (for centimeters or inches) and
(for high or low).

Examples:

(for an EU ballistic curve) means that you must
hold 1cm lower to shoot accurately

(for a US ballistic curve) means that you must

hold 4cm higher to shoot accurately.

Indication of set ballistic curve and
zeroing range

If you want to check your settings, e.g. because of
a changed hunting situation or a long time between
uses, you can quickly display the 2 values at any
time.
To do this, briefly press the secondary button twice
when the reticule or the range is displayed.

• Below the reticule (or instead of the range), the
following will appear in turn for around 2s each:
– The set ballistic curve (see page 30)
– The set zeroing range (see page 29)

31

Care/cleaning

Your LEICA RANGEMASTER CRF 1600 does not
require any special care. Coarse particles of dirt
such as sand should be removed with a soft brush
or blown away. Marks such as fingerprints on the
front lens and eyepiece lenses can be cleaned with
a damp cloth and then wiped off with a soft, clean
leather or dust-free cloth.

Important

Do not exert heavy pressure when wiping highly
soiled lens surfaces. Although the coating is highly
abrasion resistant, it can be damaged by sand or
salt crystals. The housing should be cleaned only
using a damp leather. There is a risk of static build­ing up if dry cloths are used. Alcohol and other
chemical solutions may not be used to clean the
lens or the housing. Every LEICA RANGEMASTER
CRF 1600 has a serial number in addition to its
model name. Note this number in your documenta­tion for security.

Attention:

Never open the unit.

Spare parts

Should you ever require spare parts for your LEICA
RANGEMASTER CRF 1600, such as eyepiece cups
or a carrying cord, please contact our Customer
Service department (for address, see page 35) or
your national Leica agent (for addresses, see War­ranty Card).
