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-1 or GX-2.

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

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 750 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.

Battery

The GX-1 and GX-2 have two buttons: POWER and MODE. When you initially

from other potential targets in the distance behind the pin. When you press

and hold the MODE button for 1 second, the Quick Set Munu

is prepared for

navigation. To set or activate a mode, you must advance to that function by

pressing the MODE button until that function is displayed. To activate a mode,

press the POWER button, the icon will display steadily and the word “ON” will

appear in the bottom portion of the display. Pressing the POWER button again

will turn that mode off; displaying the word “OFF” in the bottom portion of

the display. Each subsequent depression of the POWER button will toggle that

function between on and off. If this is the last mode to be set, allowing the

rangefinder to sit idle for 20 seconds will cause an automatic power-off, saving

all selections. If additional modes require activation/deactivation, simply press

MODE to continue through the Quick Set Menu.

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 range-

finder will produce an audible beep and the

lock icon will be shown in the lower left portion of the display. 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 is only active when in scan mode.

FUNCTION 1: FOG MODE

The Fog Mode can be used in foggy/rainy conditions to screen out false read-

ings 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.

3) While the word “Fog” is displayed, press and release POWER as necessary

until the word “on” is displayed in the lower portion of the display.

4) To save the changes and return to ranging mode, let the unit sit idle for at

least 20 seconds until an automatic power-down occurs, or simply press and

hold MODE for at least 1 second. To continue through the Quick Set Menu and

manipulate another feature, press and release MODE until the appropriate

icon is flashing.
