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.”

Markus Friederich

“Fred” Leupold

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.

800/731 800/731

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-3 and GX-4 have two buttons: POWER and MODE. When you initially

from other potential targets behind the pin.

MODE

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.

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 displayed.

NOTE: There is no icon for fog mode in normal operation. When powered on

the unit will display “fog on” to remind you of the current setting. We recom-

mend turning fog mode off during normal ranging to enable easy location of

the pin.

SMART KEY TECHNOLOGY:

Available only on GX-4 models, the yellow Smart Key provides True Golf Range

(TGR) and Club Selector capability. Replace the Smart Key with the included

chrome faceplate to completely disarm TGR functionality and instantly convert

the GX-4 to a device that measures or gauges distance only. Safe storage for

the Smart Key or chrome faceplate can be found inside the carrying case.

FUNCTION 2: TRUE GOLF RANGE (TGR) (GX-4 WITH SMART KEY INSTALLED ONLY)

True Golf Range is an adjusted range that will com-

pensate for uphill shots that play long and downhill

shots that play short. TGR is calculated from the line

of sight distance, incline or decline, current tempera-

ture and altitude, and will display the adjusted range

the golfer should play to. For example, if you have

a lie 150 yards from the pin, but the green falls 6

degrees above your ball, you should play the shot as if it were 164 yards.

FUNCTION 6: CLUB SELECTOR SETUP (GX-4 WITH SMART KEY INSTALLED ONLY)

When TGR is activated, the Club Selector function recommends the proper

iron for the current distance, shot angle, environmental conditions, and

multiple other factors. This will be shown in the lower portion of the

display. When ranging an object with True Golf Range activated, the

upper display will show the TGR distance, and the lower display will show

the line-of-sight distance briefly, followed by the word “club”, followed by

the club recommendation. The True Golf Range will remain visible in the

upper portion of the display.

Critical to accurate club recommendations is the known striking distance of

the user with specific clubs. By inputting the actual distance obtained with a

few clubs, a specialized algorithm accurately determines the distance obtained

with others. The actual distance obtained from an 8-iron, 6-iron, and 4-iron

shot should be input as accurately as possible. If no club distance is input, the

Club Selector will automatically default to the preset distances (130 yards for

an 8-iron, 150 yards for a 6-iron, and 170 yards for a 4-iron). In addition to the

striking distances, the temperature and altitude at which these distances were

measured must be input following the distance input process. By entering the

environmental conditions in which the specific distances were obtained, the

Club Selector will be able to adjust the recommended iron according to the

current conditions.

NOTE:

Though we strongly recommend inputting the specific distances

obtained with each of the irons mentioned above, the specialized algorithms

used by the GX-4 will make logical assumptions about the remaining club(s) if

specific distances are not known for one or more of the remaining clubs.

TGR must be activated to input the specific distances achieved with each

club. After activating TGR , setting the current temperature and altitude, and

choosing yards or meters, pressing and releasing MODE will begin the process

of entering your specific 8-iron distance. The 8-iron

indicator will be shown in the upper display, and the

last saved distance will be shown in the lower display.

Press POWER to begin incrementing through the 8-iron

distance settings. The default setting is 130 yards.

Pressing POWER will increment through a range of 60

yards to 200 yards in 5-yard increments.

When your selection is shown in the lower numeric display, press MODE to save

your selection and move on to the 6-iron.

The 6-iron indicator will be shown in the upper display,

and the last saved distance will be shown in the lower

display. Press POWER to begin incrementing through the

6-iron distance settings. The default setting is 150 yards.

Pressing POWER will increment through a range of 80

yards to 220 yards in 5-yard/meter increments. When your

selection is shown in the upper numeric display, press MODE to save your selec-

tion and move on to the 4-iron.

NOTE:

You cannot input a distance value less than or equal to the previous

club. For example, if you choose 155 yards for your 8-iron, the lowest available

distance for your 6-iron will be 160 yards.

The 4-iron indicator will be shown in the upper display,

and the last saved distance will be shown in the lower

display. Press POWER to begin incrementing through the

4-iron distance settings. The default setting is 170 yards.

Pressing POWER will increment through a range of 100 yards to 240 yards in

5-yard/meter increments. When your selection is shown in the lower numeric

display, press MODE to save your selection and move on to the temperature

input (the temperature at which these distances were measured).

NOTE:

You cannot input a distance value less than or equal to the previous

club. For example, if you choose 175 yards for your 6-iron, the lowest available

distance for your 4-iron will be 180 yards.

Once the specific distances obtained with each of the

clubs above has been input, you will be asked to input the

temperature and elevation at which these distances were

obtained. Following the input of your measured

4-iron striking distance, the next depression of MODE will

begin the process of entering the temperature at which

this distance was obtained.

The last saved temperature will be flashing in the

bottom portion of the display. Press POWER to begin

incrementing through the temperature settings. The

default setting is 75 degrees F. Pressing POWER will

increment through a range of 30 degrees to 120 degrees F in 5 degree incre-

ments. When the appropriate temperature is displayed, press MODE to save

your selection and move on to the altitude input.

The last saved altitude will be flashing in the bottom

portion of the display. Press POWER to begin

incrementing through the altitude settings. The default

setting is 1000 feet. Pressing POWER will increment

through a range of 0 feet to 9999 feet in 500 foot

increments. When the appropriate altitude is displayed,

press MODE to save your selection and move to the last

mode (aiming reticle selection).

HOW DO I INPUT THE STRIKING DISTANCE OF THE 8, 6 AND 4-IRON? (GX-4 WITH SMART KEY INSTALLED ONLY)

NOTE:

Though we strongly recommend inputting the specific distances

obtained with each of the irons mentioned above, the specialized algorithms used by the GX-4 will make logical assumptions about the remaining club(s) if specific distances are not known for one or more of the remaining clubs.

*Reminder: You cannot input a distance value less than or equal to the previous club. For example, if you choose 155 yards for your 8-iron, the lowest available distance for your 6-iron will be 160 yards.

The procedure for inputting specific striking distance begins immediately after selecting yards or meters as your desired measurement output. Follow steps 1-5 on pages 19 - 20 under the heading “How Do I Activate the Yards Mode?”, Once you have chosen the desired measurement output, press MODE and follow the steps below:

1) The 8-iron indicator will be shown in the upper display, and the last

saved distance will be shown in the lower display. If you wish to input a

distance other than the one shown, proceed to step 2. To save the

shown distance for your 8-iron, press MODE and skip to step 3 below.

2) Press POWER to set the distance obtained with your 8-iron. Each

depression of POWER will increase the distance associated with your 8-iron shot in 5-yard/meter increments beginning with the last saved distance, until 200 yards has been reached. Once 200 yards has been reached, it will reset to 60 yards, and start over again. When the appropriate distance is displayed, press MODE.

3) The 6-iron indicator will be shown in the upper display, and the last

saved distance will be shown in the lower display. If you wish to input a distance other than the one shown, proceed to step 4. To save the shown distance for your 6-iron, press MODE and skip to step 5 below.

4) Press POWER to set the distance obtained with your 6-iron. Each depression of POWER will increase the distance associated with your 6-iron shot in 5-yard/meter increments beginning with the last saved distance, until 220 yards has been reached. Once 220 yards has been reached, it will reset to 80 yards, and start over again. When the appropriate distance is displayed, press MODE.

5) The 4-iron indicator will be shown in the upper display, and the last

saved distance will be shown in the lower display. If you wish to input

a distance other than the one shown, proceed to step 6. To save the

shown distance for your 4-iron, 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 displayed.

6) Press POWER to set the distance obtained with your 4-iron shot in 5-yard/

meter increments beginning with the last saved distance, until 240 yards

has been reached. Once 240 yards has been reached, it will reset to 100

yards and start over again. When the appropriate distance is displayed,

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 mode is displayed.
