Safety Instructions
Please read these safety instructions careful-
ly and follow these guidelines when using
the product.
Never look direcly into the sun, any bright
light sources or laser based light sources
through your optical product. This can
cause irreparable eye damage. Optics in
riflscopes function as a magnifying glass,
therefore dramatically increasing the
intensity of the light source.
Store the riflescope and accessories inclu-
ded with the FLAGMASTERTM out of reach of
children. Some of our products may contain
small parts which could create a choking
hazard for small children, or nylon straps
which could create a strangulation hazard.
Be cautious when touching metal parts
ENGLISH
when the product has been stationary and
extensively exposed to the sun or the free-
zing cold, as extremely hot or frozen metal
components may cause an injury to the skin.
Avoid improper shock, such as dropping
this porduct. It is an optical instrument and
damage may occur.

FUNCTIONALITY
The FLAGMASTER uses an infrared laser and detector
to accurately determine the range to a target. By
emitting a series of eye-safe laser pulses and then
determining the time it takes for those pulses to travel
to and return from the target, the FLAGMASTER can
calculate an exact distance. The rangefinder system
leverages advanced algorithms running within the
digital signal processor to improve range performan-
ce and extend the maximum range performance of
the device.
MEASURING ACCURACY
AND TARGET TEXT
Under normal conditions, the measurement accuracy
is +/-1 yards up to a distance of 1,000 yards. From a
distance of 1,000 yards to1,800 yards, the measu-
rement accuracy is +/-2 yards. The measurement
accuracy and distance depends largely on the reflec-
tivity of the target and the environmental conditions
at the time of the measurement. Depending on the
reflectivity of the target and environmental conditions,
the maximum distance and measurement accuracy
may vary. Color, surface texture, size, shape, fog, rain,
measurement angle and scattered light influence the
measurement positively or negatively.
Target color shiny surfaces = high reflection properties
Target color black = low reflection properties
Sunshine = shorter range
Covered sky = longer range

SET-UP AND INITIAL USE
Insert and replacing the battery
The package includes a CR2 battery. Remove the
battery from the packaging. Flip up one half of the
battery cover. With this lever you turn the battery
compartment counterclockwise to open the battery
compartment. Insert the CR2 3-Volt lithium battery
with the negative contact facing into the battery
compartment. Close the battery compartment with
the battery cover, turning clockwise. Hand-tighten
the battery cover and fold the clip back to its starting
position. Be careful not to over tighten because the
battery cap can break the flip lever. If the battery cap
is not installed properly the battery compartment may
not seal properly.
Please check the battery every 3 months to prevent
battery leakage.
Most CR-2 batteries will run for several years in your
rangefinder; however we recommend replacing the
battery every year. Please always dispose of the bat-
tery in designated containers or dispensing stations
(see details in chapter „Disposal of electrical and
electronic equipment“).

SETTING THE EYEPIECE
The FLAGMASTER is equipped with a SpeedFocusTM
diopter adjustment. This is located near the eyepiece.
The eyepiece adjustment can be set between +/- 3
diopters. Look through the eyepiece and rotate the
SpeedFocusTM by turning the focus wheel in the + or -
direction, depending on your personal eye prescrip-
tion. Rotate the SpeedFocusTM for best focus of the
display in relation to the image so that you can clearly
resolve both objects at the same time.
CONNECTING THE STRAP
Your FLAGMASTER comes with a lanyard or retaining
strap. This strap ensures safe handling of the product.
Guide the thin end of the strap loop through the strap
connection on your FLAGMASTER. Slide the thicker
end through the loop of the thin end and tighten the
strap. With the slider button you can change the loop
size that fits in your wrist. Please do not pull the loop
too tightly to avoid injury.

PinFinder
Your FLAGMASTER has a PinFinder which allows you
to specifically range the flag. Some courses use a
retroreflector or prism mounted on the top of the pin.
In PinFinder mode you will see the flag symbol on the
display. Move the target or aiming point of the display
towards the flag or top of the pin and you will feel a
vibration if the vibration is active.
Press and hold the Range button (A) (your FLAGMAS-
TERTM will automatically enter Scan mode). Carefully
move the aiming point over the flag or prism to while
the Range Button is held down. If you have locked in
on the flag or prism a circle will appear around the
flag icon and you will feel a vibration if the vibration
is active and in the display confirming you have a pin
lock. Upon release of the range button, the distance
will be displayed for 10 seconds.
SCAN MODE
Your FLAGMASTER gives you the option of single ran-
ge measurement or scan mode. For a single distance
measurement, aim the rangefinder at the intended
target then press and release the range button. For
scan mode, aim the rangefinder and press and hold
the range button – the device will scan for up to 20
seconds providing 3 updates per second. Scan mode
is useful for ranging distance targets or when the flag
is blowing in the wind. Upon release of the range
button the last, best range result will be displayed for
10 seconds.

Line of Sight (LOS) mode or SLOPE
setting
You can set the FLAGMASTER via a preset, step by
step menu.
Press the Range button to activate the FLAGMASTER.
Then press the Mode button for 2 seconds.
The display will show LOS = Line of Sight (flashing).
LOS is the currently set mode. To change this to SLO-
PE = press the Range button and you will see SLOPE
displayed. Press the Mode button again to save the
set value.
Your FLAGMASTER offers you 2 different ways of
determining distance. The first one is LOS (Line of
Sight). The LOS mode measures the direct distance to
a target without consideration of an angle. The SLOPE
tells you the equivalent horizontal distance (or angle
modified distance) with consideration of the angle.
INFORMATON ABOUT SLOPE
Your FLAGMASTER has a built-in tilt sensor that de-
termines the exact tilt angle up to ± 60 degrees. Your
FLAGMASTER automatically calculates the adjusted
distance based on the measured distance and angle.
When your FLAGMASTER is in the LOS (Line of Sight)
mode, you will be alternately shown a distance of 500
meters and the measured angle.
If the FLAGMASTER is in the SLOPE mode, the adjus-
ted distance of 433 meters is displayed, taking into
account a 30° angle.
Example:
LOS Range of 500
yards. 30° decline
equals to an AMR of
433 yards

EN

Setting the SLOPE indicator
Some official tournaments do not allow the use of
the SLOPE mode. Your FLAGMASTER allows you to
disable this mode. After pressing the mode button
the setup menu is activated. There you can choose
between SLOPE ON or OFF. If SLOPE is enabled, you
will see the adjusted distance. If the SLOPE mode is
disabled, it will not be available. In addition, you and
the official in front of the FLAGMASTER will see two
red flashing triangles showing the activated SLOPE
mode. To turn on the SLOPE, repeat until SLOPE ON is
displayed. Confirm this with the Mode button.
In SLOPE mode, the red LEDs on the faceplate will
flash during ranging.
