1 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.
3 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.
5 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. Stateof-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.
Specifications The GX Series of digital laser rangefinders provides a variety of useful modes . to tailor performance to the conditions you experience in the field. Model . features are identified on the following pages.
7 Operation QUICK SET MENU™ *GX-4 display shown with all possible modes visible
GX-3 & GX-4 POWER Focus MODE Battery The GX-3 and GX-4 have two buttons: POWER and MODE. When you initially s from other potential targets behind the pin.
9 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 manipulate 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 automatic power-off, saving all selections.
Using Prism Lock Many courses have highly reflective prisms included in key course features. These prisms provide 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.
11 FUNCTION 1: FOG MODE The Fog Mode can be used in foggy/rainy conditions 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.
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.
13 FUNCTION 2: TRUE GOLF RANGE (TGR) (GX-4 WITH SMART KEY INSTALLED ONLY) True Golf Range is an adjusted range that will compensate 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 temperature and altitude, and will display the adjusted range the golfer should play to.
When entering the Quick Set Menu, TGR is the second mode encountered. TGR will be shown in the upper display, and the lower display will show whether it is on or off. Press POWER to toggle TGR on and off. Press MODE to save your selection and move on to the next function. NOTE: Turning TGR off will also disable the Club Selector and inclinometer display; all distance readings will be line-of-sight measurements.
15 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. FUNCTION 3: CURRENT TEMPERATURE INPUT (GX-4 WITH SMART KEY INSTALLED ONLY) Temperature is one of the factors used to determine TGR ranges; inputting the current temperature will increase the accuracy of your TGR measurement. The default temperature setting is 75 degrees F.
HOW DO I MANUALLY INPUT THE CURRENT TEMPERATURE? (GX-4 WITH SMART KEY INSTALLED ONLY) 1) Press POWER to activate the rangefinder. 2) Press and hold MODE for at least 1 second to enter the Quick Set Menu. 3) Verify that TGR is turned on; if TGR is not activated, you will not be able . to enter the current temperature. To activate TGR, see “How do I . activate TGR?” above. 4) Press and release MODE again; the last saved temperature will be . flashing in the lower portion of the display.
17 FUNCTION 4: ALTITUDE INPUT (GX-4 WITH SMART KEY INSTALLED ONLY) Altitude is one of the factors used to determine . TGR ranges; inputting the local elevation/altitude will increase the accuracy of your TGR measurement. The default altitude setting is 1000 feet, and will be shown in the lower portion of the display. After . activating TGR, continue to press and release MODE. The last saved current temperature will be displayed, followed by the last saved current altitude.
3) Verify that TGR is turned on; if TGR is not activated, you will not be able . to enter the current temperature or altitude. To activate TGR, see “How . do I activate TGR?” above. 4) Press and release Mode; the last saved current temperature will now . be flashing. Press and release MODE again and the last saved current . altitude will be flashing. 5) While the altitude is flashing, press and release POWER to change the . current altitude setting to match current conditions; each depression of .
19 FUNCTION 5: YARDS/METERS This mode allows you to toggle between yards or meters for the measurement output unit. When set to yards mode, all temperature settings will be in Farenheit. When set to meters mode, all temperature settings will be in Celsius. To toggle between yards mode and meters mode, progress through the mode options until Set Up flashes momentarily in the display. The word “Unit” will then show steadily in the lower portion of the display, along with a Y for yards or an M for meters.
3) Press and release MODE until Set Up flashes briefly in the display, followed by the word Unit shown steadily in the lower display. 4) While the word Unit is shown in the lower display, press and release POWER as necessary to toggle between yards and meters, which will be shown in the lower right portion of the display. release .
21 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.
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.
23 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.
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.
25 increment through a range of 30 degrees to 120 degrees F in 5 degree increments. 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.
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.
27 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.
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.
29 HOW DO I INPUT THE TEMPERATURE AND ALTITUDE AT WHICH THE STRIKING DISTANCE FOR EACH CLUB WAS MEASURED? (GX-4 WITH SMART KEY INSTALLED ONLY) The procedure for inputting the temperature and altitude at which each striking distance was measured begins immediately after choosing between yards or meters as the desired measurement output. Follow each of the steps above under “How do I input the striking distance of the 8, 6 and 4-iron?” Once the striking distances have been input, press MODE and follow .
When the appropriate temperature is displayed, press MODE to save your selection and move on to the altitude input. 3) The last saved altitude will be flashing in the bot tom portion of the display. If you wish to input an altitude other than the one shown, proceed to step 4. To save the shown altitude 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.
31 4) 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 9,999 feet in 500 foot increments. When the appropriate altitude is displayed, you have completed the input process for setting up the temperature and altitude at which the striking distances were measured.
