Introduction
Congratulations! You have purchased a Leupold® GX Series digital laser
rangefinder that has been crafted by Leupold’s engineers and designers to
be the best rangefinder on the market, and to provide you with years of solid
performance on the course. Following are instructions detailing the proper use
and employment of your GX Series rangefinder. To ensure top performance for
the life of the product, please read these instructions before operating your
GX-3 or GX-4.
About Leupold & Stevens, Inc.
It’s a decidedly American story: in 1907, a young German immigrant named
Fred Leupold set up a one-man shop at 5th and Oak Streets in Portland,
Oregon, repairing optics for surveying equipment. The small company survived
the First World War and the Great Depression. But it was the Second World
War that would forever change the company. Working with the U.S. Army
on a riflescope and the Navy on optics for use aboard ships, the engineers at
Leupold® learned the secrets of waterproofing and durable construction that
would completely change the world of sports optics.
Leupold & Stevens, Inc. is still family-owned, though the focus has turned from
land surveying to helping people across the globe survey their environments
with innovative, high-performance optics and accessories. Leupold optics are
renowned for their unchallenged ruggedness, absolute waterproof integrity,
and their vastly superior optical quality. A century of observation and optical
experience has gone into every product we produce, and we think the results
are well worth the extra effort required to achieve this level of quality.

In true American style, the philosophical foundation laid in our early years has
served us well as we’ve grown and changed over the decades. In fact, the firm’s
founder established the clarity of purpose that we see at Leupold & Stevens, Inc.
today:
“We solemnly promise never to let down on quality, the customer is entitled to
a square deal.”

Accuracy
The ranging accuracy of the GX series of rangefinders is +/- one yard/meter. The
maximum effective range depends upon a number of factors including lighting
conditions and air quality, but the most important factor is the reflectivity of the
target. For most objects, the maximum distance is 600 yards, while for highly
reflective targets, distances of 800 yards can be obtained.

How it Works
The Leupold GX series of rangefinders emit a series of invisible, infrared energy
pulses that are reflected off the selected target back to the optical unit. State-
of-the-art circuitry and precision computing circuits are used to calculate the
distance instantaneously by measuring the time it takes for each pulse to travel
from the GX rangefinder to the object and back.
Surface texture, color, size, and shape of the target all affect reflectivity, which
in turn affects the maximum range of the instrument. As a rule of thumb,
brightly colored targets are much more reflective than darker targets, with
black being the least reflective color. A shiny surface is more reflective than
a dull surface. Smaller targets are more difficult to range than larger targets.
Light conditions, haze, fog, rain, and other environmental conditions can all
affect ranging performance. Any factor which degrades air clarity will reduce
the maximum effective range. Bright light shining directly on the lenses reduc-
es the effectiveness, producing shorter maximum ranges than those possible on
darker (overcast) days. The steadier the GX unit is held, the greater the
maximum distance.

When you press and hold the MODE button for 1 second, the Quick Set Menu
is activated. To set or activate a mode, you must advance to that function by
pressing the MODE button until that function is displayed. To activate or manip-
ulate a mode, press the POWER button as necessary. If this is the last mode to
be set, allowing the rangefinder to sit idle for 20 seconds will cause an auto-
matic power-off, saving all selections. If additional modes require manipulation,
simply press MODE to continue through the Quick Set Menu.
To reset your GX-3 or GX-4 to factory settings, press POWER to activate the
unit. With the rangefinder activated, press and hold MODE, then immediately
press and hold POWER while continuing to hold MODE depressed. After the
10-second timer shown in the display reaches zero, the rangefinder will return
to factory settings.
Using Prism Lock
Many courses have highly reflective prisms included in key course features. These prisms pro vide your GX rangefinder with an extremely intense return signal, allowing it to lock onto the prism quickly and provide instant feedback that you have accurately ranged the intended target. When using scan mode to range a course feature with integral prisms, your GX range­finder will produce an audible beep and the Prism Lock bracket will be displayed along with the measured distance. If True Golf Range has been activated, the TGR distance and Club Selection will be shown (GX-4 with yellow Smart Key installed only). If True Golf Range (GX-4 with yellow Smart Key installed only) has not been activated, or you are using a GX-3, the line of sight distance will be shown. Prism Lock is always activated and will automatically detect the presence of prisms in course features when
scanning at a distance of 25 yards or greater.
NOTE: Prism lock will only work in scan mode; you must press and hold the
POWER button for your GX rangefinder to lock onto a prism.

FUNCTION 1: FOG MODE
The Fog Mode can be used in foggy/rainy condi-
tions to screen out false readings from raindrops
or other atmospheric interference to provide an
accurate range.
When entering the Quick Set Menu, Fog Mode is
the first mode encountered. The word “Fog” will
appear in the upper display and the lower display
will show whether it is on or off. Press POWER to
toggle Fog Mode on and off. Press MODE to save your selection and move on
to the next function.
How do I activate Fog Mode?
1) Press POWER to activate the rangefinder.
2) Press and hold MODE for at least 1 second to enter the Quick Set Menu;
the word “Fog” will now appear in the upper display.
