You have purchased a Leupold® GXTM 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-I or GX-II . 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 . 2 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 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 750 yards can be obtained . MaxiMuM Range Condition Reflective target (yd/m) trees (yd/m) Pin (yd/m) gx-i 750/675 600/550 350/318 gx-ii 750/675 600/550 350/318 4 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 . 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 lighting conditions (sunny) reduce 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 . Specification The GX Series of digital laser rangefinders provides a variety of useful modes to tailor performance to the conditions you experience in the field .

When you initially push the POWER button, the display is activated and the unit it ready for ranging . Press the Power button a second time to range, or hold the Power button depressed to scan . Scanning automatically updates the display . When ranging without a steady rest at long distances, you can easily differentiate the pin . 8 9 from other potential targets in the distance behind the pin . When you press and hold the MODE button for 1 second, the Quick Set MenuTM 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 flashing . 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; removing the icon and 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 . Pressing and holding MODE for at least 1 second at any time will exit the Quick Set Menu, save all previous changes, and prepare the rangefinder for immediate use . Hold POWER and MODE simultaneously for at least 10 seconds to reset factory settings . FUNCTION 1: TRUE GOLF RANGE (TGR) (GX-II ONLY) TGR 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 . For example, if you have a lie 150 yards from the pin, but the green falls 6 degrees above your ball, you will play the shot as if it were 164 yards .
