  • Page 4: About Leupold & Stevens, Inc

    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.
  • Page 5 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.”...

  • Page 6: Accuracy

    ACCURACY The ranging accuracy of the GX series of rangefinders is +/- .5 yard/meter. The maxi- mum 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 550 yards, while for highly reflective targets (such as pin prisms), distances of 700 yards can be obtained.

  • Page 7: How Gx Rangefinders Work

    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 rangefinder to the object and back.

    OPERATION QUICK SET MENU ™ *GX-4i display shown with all possible characters visible...
  • Page 12 GX-3 & GX-4 POWER FOCUS MODE BATTERY The GX-3i and GX-4i have two buttons: POWER and MODE. When you initially press the POWER button, the display is activated and the unit is ready for ranging. Press the POWER button a second time to range, or hold down the POWER button to scan.
  • Page 13 When you press and hold the MODE button for 1 second and then release it, 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 function, press the POWER button as necessary.
  • Page 14 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. Fog Mode changes the algorithm to look for the “last” target. To increase ranging accuracy always range the ground around the pin/flag when Fog Mode is on.
  • Page 15 4) To save the changes and return to ranging mode, let the unit sit idle for at least 30 seconds until an automatic power-down occurs, or simply press and hold MODE for at least 2 seconds. To continue through the Quick Set Menu and manipulate another feature, press and release MODE until the appropriate icon is displayed.
  • Page 16 FUNCTION 2: TRUE GOLF RANGE (TGR) (GX-4i 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.
  • Page 17 NOTE: Turning TGR off will also disable the Club Selector and inclinometer display; all distance readings will be line- of-sight measurements. TO ACTIVATE TGR: 1) Press POWER to activate the rangefinder. 2) Press and hold MODE for at least 1 second and then release to enter the Quick Set Menu;...
  • Page 18 FUNCTION 3: DAY OF PLAY (dP) TEMPERATURE INPUT (GX-4i 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 (25 degrees C).
  • Page 19 MANUALLY INPUT THE DAY OF PLAY TEMPERATURE: 1) Press POWER to activate the rangefinder. 2) Press and hold MODE for at least 1 second and release 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, see “To Activate TGR:”...
  • Page 20 FUNCTION 4: DAY OF PLAY (dP) ALTITUDE INPUT (GX-4i 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.
  • Page 21 5) While the “Alt” is flashing, press and release POWER to change the current altitude setting to match current conditions; each depression of POWER will increase the altitude setting by 500 feet until 9999 has been reached, at which time the setting will return to 0 and begin increasing again. 6) To save the changes and return to ranging mode, let the unit sit idle for at least 30 seconds until an automatic power-down occurs, or simply press and hold MODE for at least 2 seconds.
  • Page 22 FUNCTION 5: CLUB SELECTOR (GX-4i WITH SMART KEY INSTALLED ONLY) NOTE: If TGR is not activated, you will not be able to use the CLUB SELECTOR function. When TGR is activated, the Club Selector function recommends the proper iron for the current distance, shot angle, environmental conditions, and multiple other factors.
  • Page 23 TO ACTIVATE CLUB SELECTOR: 1) Press POWER to activate the rangefinder. 2) Press and hold MODE for at least 1 second and then release 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 club selections.
  • Page 24 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.
  • Page 25 FUNCTION 6: YARDS/METERS MODE NOTE: “SET UP” will briefly flash before transition to 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.
  • Page 26 5) To save the changes and return to ranging mode, let the unit sit idle for a least 30 seconds until an automatic power-down occurs, or simply press and hold MODE for at least 2 seconds. If yards is selected, the temperature will automatically be measured by Fahrenheit.
  • Page 27 FUNCTION 7: CLUB SELECTOR SETUP (SU) (GX-4i WITH SMART KEY INSTALLED ONLY) 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.
  • Page 28 last saved distance, until 200 yards (185 meters) has been reached. Once 200 yards (185 meters) has been reached, it will reset to 60 yards (55 meters), and start over again. When the appropriate distance is displayed, press MODE. 6) The 6-iron indicator will be shown in the upper display, and either the last saved distance or 8-iron distance plus 20 yards will be shown in the lower display.
  • Page 29 8) The 4-iron indicator will be shown in the upper display, and either the last saved distance or 6-iron distance plus 20 yards will be shown in the lower display. If you wish to input a distance other than the one shown, proceed to step 9. To save the shown distance for your 4-iron, let the unit sit idle for at least 30 seconds until an automatic power-down occurs, or simply press...
  • Page 30 INPUT THE TEMPERATURE AND ALTITUDE AT WHICH THE CLUB SELECTOR SETUP WAS MEASURED. Once the striking distances have been input, press MODE and follow the steps below: 1) The last saved Temperature will be flashing in the bottom portion of the display. If you wish to input a temperature other than the one shown, proceed to step 2.
  • Page 31 3) The last saved Altitude will be flashing in the bottom 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 30 seconds until an automatic power-down occurs, or simply press and hold MODE for at least 2 seconds.
