Getting the most out of your new laser rangefinder
Introduction
Congratulations! You have just purchased one of the most affordable, quality laser
rangefinders on the market today. Your LR1500-SLOPE rangefinder was manufactured
by a leading, photo-optics company specializing in precision laser rangefinders and
binoculars. We are certain that you’ll be happy with your purchase and enjoy years of
solid performance.
To ensure you get the most out of your rangefinder, we have written this short user
guide to supplement the manufacturer’s manual. Please read this guide carefully before
you start using your LR1500-SLOPE laser rangefinder.
How the LR1500-SLOPE works
LR1500-SLOPE is a precision-made, 8x30mm monocular that incorporates a state-of-
the-art laser rangefinder. The rangefinder sends out a series of infrared energy pulses
that are reflected off the desired target. Precision-made optics and built-in computer
circuits are used to calculate the distance by precisely measuring the time taken for
each pulse to return. This unit is capable of measuring distances to a reflective target up
to 1500 yards (1400 meters) away.
Understanding the factors that influence distance readings
Manufacturers specify maximum distance ranges only as a reference for the user.
Actual maximum distances measured will vary depending on a number of factors.
Factors such as surface texture, size, color, shape and reflectivity of the target will all
affect the ranging performance of the instrument. In general, large, bright-colored
objects are easier to range than small, dark-colored ones.

Weather and light conditions may also affect ranging performance. Users are often
surprised to find out that bright, sunny conditions (particularly when ranging towards the
sun) can cause decreased performance. This is because infrared energy produced by
the sun can interfere with the infrared energy pulses produced by the rangefinder.
A clear line-of-sight to the target is also a critical determinant affecting ranging
performance. For example, overhanging branches in the foreground can reflect the laser
intended for the target further away and provide shorter distance readings. Conversely,
shrubs and trees in the background of a small target may reflect more of the laser
causing inaccurate readings. These issues are common to all laser rangefinders
(including Bushnell and Nikon brands).
Your laser rangefinder comes with 5 special – STANDARD, SCAN, BEELINE, HIGH, and
ANGLE – measurement modes. “STANDARD” mode is the default mode your rangefinder
will be set to and will the mode you will use under most conditions. SCAN mode allows
the user to “scan” the target and surrounding area to get continuous distance
measurements. BEELINE, HIGH and ANGLE modes provide angle compensated True
Horizontal Distance, the Height of the object and the Angle to the horizontal,
respectively.
GETTING STARTED
Getting the LR1500-SLOPE set up for use will be a breeze if you follow these steps:
A) Installing Batteries
1) Remove the LR1500-SLOPE from the box and unpack contents
2) Open the battery compartment by turning the battery cap counter-clockwise.

Insert CR123A (3V) battery paying attention to the polarity. The positive (+) end of
the battery should point away from the battery compartment.
3) Close cap by turning clockwise. When correctly placed on, the battery compartment
cap should sit flush with the body.
B) Understanding the buttons
There are only 2 buttons (“ON” and “MODE”) on the LR1500-SLOPE laser rangefinder.
The “ON” button is used to turn the unit on. The unit will shut down automatically after 10
seconds of inactivity so there is no need to switch the unit off. Once on, the “ON” button
also serves to activate distance measurement.
The “MODE” button is used to change 1) measurement units from YARDS to METERS
and; measurement modes (STANDARD, BEELINE, HIGH, ANGLE).
C) Changing measurement UNITS
1) Turn on power by pressing the “ON” button once
2) Look through the eye-piece and note the measurement unit. If the unit displayed
is not the desired unit (e.g. METERS (MS)) then, press the “MODE” button down
for 3 seconds or until the units change to YARDS (YDS). To change back to
METERS, hold the “MODE” button down for 3 seconds.
D) Changing measurement MODES
1) Turn on power by pressing the “ON” button once
2) Look through eye-piece and note the MEASUREMENT MODE on the top LEFT of the

!

LCD display. If no mode is displayed, you are in the STANDARD mode.
3) To change to another mode, press the “MODE” button once. The word “BEELINE”
should appear indicating that you are now in “BEELINE” or Angle-compensated,
True Horizontal Distance mode. Press the “MODE” button again until the desired
mode setting is displayed. The order in which the Modes appear is:
STANDARD, BEELINE, HIGH and ANGLE.
E) Measuring distances
Go outside ….. it’s time to test out your new rangefinder!
We recommend you test the rangefinder on trees first until you familiarize yourself with
the operation.
1) Turn power ON by pressing the “ON” button once
2) Look through the eye-piece and aim the reticle (the cross-shaped lines in your
viewfinder) to a tree (or another object) at least 10-15 yards away.
3) Turn the eye-piece clockwise or counter-clockwise until the desired target is in focus.
(Note: The eye-piece can be expanded or retracted depending on your preference).
4) To measure distance to the target, just press the “ON” button once. Voila! The
distance measurement should appear on the viewfinder instantly.
5) For more measurements, aim the reticle at another target and press the “ON” button
once. It’s that simple.
6) If the word “End” appears on the LCD instead of a number, try holding the “ON”
button down a little longer during measurements. If the word “End” still persists on the
LCD then 1) your target may be too close …. objects <10-15 yards away may not be
measureable; 2) there may be something blocking the lens or the laser; 3) the target is

too far away or does not have favorable properties (see “Understanding factors that
influence distance measurements” on pages 2-3).
7) The unit turns off automatically after 15 seconds of inactivity so there is no need to
shut the unit down.
SCAN (continuous measurement) mode
SCAN mode is activated by holding down the “ON” button continuously as you aim at
the target. The distance measurements will continuously update as you point to a
different target. Release the “ON” button to stop measurements.
A Note about using SCAN:
In addition to the single measurement approach, the “SCAN” function can also be
effectively used to measure the distance to difficult to acquire targets such as the
golf pin. To do this, aim the reticle at the pin and press “POWER” to activate SCAN
measurements. Keep the reticle aimed at the pin as much as possible and take note
of the blinking measurements. The distance to the pin is shortest distance displayed.
For example, if the continuous measurements read: 185…156….179….155….184.
The distance to the golf pin is 155 yards. The other distances are probably to the
trees or shrubs behind the green.
F) Care and Maintenance
This unit is built to be water-resistant (it is not waterproof). Appropriate care should be
taken to prevent exposure to water. Excess moisture (particularly near the battery
compartment and buttons) should be wiped off immediately to minimize chances of
damage to the internal computer circuitry. As a general rule, treat this rangefinder like
you would a digital camera or a cell phone. It is imperative that the optics be kept clean
for proper function. Wipe off stains and smudges from the lens surface using a clean,

soft cotton cloth or oil-free lens tissue. For stubborn stains, a small amount of pure
alcohol can be used. Please take care of your optics, as dirty or scratched objectives
will negatively affect the performance of your laser rangefinder.
WARNING: Do not point the rangefinder directly at the sun. Doing so could result in
serious injury to your eyes.
