Safety Precautions (Laser)
The Apresys eXpert Laser Rangefinder uses an invisible laser beam. Make sure to observe the following:
•Do not activate the measurement function while looking into the optics from the objective side.
Failure to do so may negatively affect or damage your eyes.
•Do not aim at an eye.
•Do not point the laser at people.
•Do not look at the laser through another optical instrument.
•When not in use for an extended period, the battery should be removed from the compartment.
•Keep the Apresys eXpert Laser Rangefinder out of reach of children.
Safety Precautions (Optical)
The Apresys eXpert Laser Rangefinder uses an optical system in order to aim at a target. Make sure to
observe the following:
•Never look directly at the sun, an intense light source or laser beam when using the Apresys
eXpert Laser Rangefinder.
•Do not use this product when walking. Failure to do so may cause injury or malfunction as a
result of walking into something, hitting others, falling or other accidents.
•Do not swing around by the strap.

If handled incorrectly, the battery may rupture and leak, corroding equipment and staining clothing.
Make sure to observe the following:
•Install the battery with + and – poles correctly positioned.
•The battery should be removed when exhausted or during extended period of non-use.
•Do not short the end terminal of the battery compartment.
•Do not carry the battery together with keys or coins in a pocket or bag, it may short and cause
overheating.
•Do not expose the battery to water or flame. Never disassemble the battery.
•Do not charge the lithium battery.
•If liquid from a damaged battery comes into contact with clothing or skin, rinse immediately
with plenty of water. If liquid from a damaged battery comes into contact with eyes, rinse
immediately with clean water and consult a doctor.

Safety Precautions (General)
•Although the Apresys eXpert Laser Rangefinder is waterproof, it is not designed to be
submersible.

•Rain, water, sand or mud should be removed from the body of the product as soon as possible,
using a soft, clean cloth.
•Do not leave the Apresys eXpert Laser Rangefinder in a car on a hot or sunny day, or near a
heat-generating equipment. Doing so may negatively affect its operation.
•Do not leave the Apresys eXpert Laser Rangefinder in direct sunlight. UV and excessive heat may
negatively affect or damage the unit.
•If the Apresys eXpert Laser Rangefinder is exposed to sudden changes in temperature,
condensation may occur on lens surfaces. Do not use this product until such condensation has
evaporated.
Care and Maintenance (Lenses)
•When removing dust from the lens surface, use a soft, oil-free brush.
•When removing stains or smudges, like fingerprints, from the lens surface, wipe the lenses very
gently with a soft, clean, lint-free cloth or quality oil-free lens tissue. Once a cloth has been used
for cleaning the body, it should not be used for lens surface.
Care and Maintenance (Main Body)
•Clean the body with a soft, clean cloth. Do not use cleaners containing solvents.
Storage
•Water condensation or mold may occur due to high humidity. It is recommended to store the
Apresys eXpert Laser Rangefinder in a cool, dry place.
•After use in inclement weather, thoroughly dry the Apresys eXpert Laser Rangefinder at room
temperature, then store it in a cool and dry place.
Key Features
•High quality 6X monocular with multilayer coating.
•Clean, intuitive display.
•Multiple modes.
•Advanced data selection, including angle compensation.
•Automatic power shot-off (after approx. 15 sec of non-operation)
•Waterproof design for inclement weather (NOT submersible).
•Invisible/Eyesafe Class 1 Laser
The Apresys eXpert Laser Rangefinder uses an invisible laser beam for measurement. In simplified
terms, it calculates the time it takes the laser beam to travel to the target and back. Laser reflectivity
and accuracy of the results may vary according to climatic and environmental conditions, as well as
the color, surface finish, size, shape, and other characteristics of the target.
Distance and accuracy of the measurements may be increased by the following conditions:
•Overcast weather
•Bright-colored target
•Target with reflective surface
•Large size target
•Angle of the laser beam to the target is equal, or close to, 90°

Distance and accuracy (or even failure) of the measurements may be decreased by the following
conditions:
•Non-reflective target surface
•Diffusive reflective target surface
•Dark-colored target
•Low visibility conditions (snow, rain, or fog)
•Target measured through glass
•Obscured target

8. Aiming reticule
9. Line of sight distance display
*The display of this product is magnified by the high magnification of the eyepiece. Although the display
is produced using the most advanced technology available, it is impossible to completely illuminate dust.
As a result, some dust particles may be seen through the eyepiece. This will not affect measurement
accuracy or environmental rating of the product.
Measurement data selection
*The line of sight distance will always display at the top of the display.
1. Turn on the power by briefly pressing the ▲button (confirm that the display is on by looking
through the eyepiece).
2. Press and hold (approx. 3 sec) the MODE button to cycle through available options
Indicates slope angle (degrees)
Indicates vertical distance between level (0° slope) and point of
measurement (yards/meters)
Indicates horizontal (angle adjusted) distance to point of
measurement (yards/meters)

Target Priority (Hunting/Golf) Mode selection
1. Turn on the power by briefly pressing the ▲button (confirm that the display is on by looking
through the eyepiece).
2. Briefly press the MODE button to switch between Distant Target Priority / Hunting ( ) and Close
Target Priority / Golf ( ) mode. When neither icon is illuminated, standard mode is in effect and no
special priority will be assigned.
Distant Target Priority / Hunting mode will disregard close
obstructions such as brush and tree branches when calculating
range. If two overlapping objects are measured, the distance to
the farther object will be displayed.
Close Target Priority / Golf mode will give priority to closer
targets while disregarding a possibly stronger return from
larger background. If two overlapping objects are measured,
the distance to the closest object will be displayed.
Units of measure and Saved data selection
The Apresys eXpert Laser Rangefinder can display the measurement data in either meters or yards. It
will also record the last 100 measurements (in Single mode only) to be recalled at a later time.
1. Turn on the power by briefly pressing the ▲button (confirm that the display is on by looking
through the eyepiece).
2. Press and hold the MODE button. Within 2 seconds (and while holding down the MODE button)
press the ▲button to cycle through Meters (M), Yards (Y), and Saved (DATA) options. Release the
MODE button to choose the option currently showing on the display.
3. In the Saved (DATA) mode, the ▲button will display the latest saved readings (100 →01). The
MODE button will display the oldest saved readings (01 →100). To exit the Saved (DATA) mode,
press and hold the ▲button for approx. 2 seconds.
Changing the battery
The Apresys eXpert Laser Rangefinder uses 3V CR2 (x1) battery.
1. Open the battery compartment cover.
2. Replace the old 3V CR2 Lithium battery with a new one (ensure that the negative terminal of the
battery is inserted first).
3. Close the battery compartment cover.
Measurement
1. Install a battery in the battery compartment (See “Changing the battery”)
2. Turn on the power by briefly pressing the ▲button (confirm that the display is on by looking
through the eyepiece).
3. Adjust the diopter to obtain a clear display through the eyepiece.

4. Confirm that each mode and setting is correct (refer to the relevant sections of this manual).
5. Position the target in the center of the aiming reticule.
5.1. For Single measurement mode, press and release the ▲button. The result will display
momentarily and stored in memory.
5.2. For Scan / Continuous measurement mode, press and hold the ▲button while slowly moving
the rangefinder from one target to next. The results will refresh as each new data is obtained,
but will not be stored in memory.
