1 Introduction Congratulations! You have purchased a Leupold® RX-600 / RX-750 Series digital laser rangefinder that has been designed by Leupold’s engineers and designers to be the best rangefinder on the market and to provide you with years of solid performance in the field. Following are detailed instructions regarding the proper use and employment of your RX rangefinder. To ensure top performance for the life of the product, please read these instructions before operating your RX-600 / RX-750.
rangefinders only provide a linear distance to your target. TBR delivers the ballistic equivalent range to the target, accounting for the effects of inclines or declines on the path of your bullet or arrow. Other features that are provided for firearms are outputs that display either MOA adjustments, or inches /centimeters of holdover at that specific distance. TBR eliminates any potentially significant error, and provides a precise range for your aiming calculations.
3 Safety and Operation Precautions The Leupold RX-600 and RX-750 6x22mm rangefinders employ an eye safe FDA Class 1 and CE Class 3A laser in their operation.
RX-600/750 Features at a Glance POWER • Laser Radiation: FDA Class 1 / CE Class 3A FOCUS • Measurement Range: 5 yds – 600 / 750 yds • Measuring Time: Less than 1 second -/+ RX-I MODE • Auto Power Off after 7 seconds • Power: CR2 battery or equivalent • Battery Life: At least 3,000 measurements • Accuracy: +/- 1 yard/meter • The RX-600 / 750 are weatherproof BATTERY 4
5 Battery Power Status Indicator To determine your battery’s power level, look for the following indicators: FULL – A full battery bar indicates your battery is at or near peak capacity. HALF – A half-full bar indicates your battery has reached half-capacity. LOW – If the battery bar is empty, yet there is still data displayed above the bar, the battery is nearing the end of its life and should be replaced.
CONTINUOUS MEASUREMENT OF A MOVING TARGET / SCAN MODE: 1. Follow the instructions for “Measuring distance…” as explained previously. 2. Once the target has been measured, continue to hold down the POWER button and follow the object as it moves. 3. The distance will automatically update as long as the POWER button is continuously depressed. 4.
7 Following is a reference table listing the ranges of the various models under different conditions: CONDITION Reflective Target (yd/m) Trees (yd/m) Deer (yd/m) MAXIMUM RANGE RX-600 600/550 500/455 400/365 RX-750 750/685 600/550 500/455 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.
8 Specifications The RX-600 and RX-750 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.
Operation Quick Set Menu™ T TGT LAS RFL BOW *Display shown with all possible modes visible 9
10 QUICK START MENU When you initially push the Power button, the unit is ready for scanning. To enter the Quick Set MenuTM, press and hold the MODE button for at least 1 second. To manipulate a function, press the MODE button until that function is displayed, then use the POWER button to change the setting. If this is the last function to be changed, you can allow the rangefinder to sit idle for 20 seconds which will cause an automatic power-off, saving all selections.
FUNCTION 1: Rifle MODE (RFL) (RX-750 model only) TBR calculates the equivalent horizontal range (level fire range) from which you can determine the correct aim for the conditions. For example, if you are shooting a .270 caliber, 130 grain bullet at 3,050 feet per second up a 30° incline at 400 yards, direct line of sight, the TBR output will be 372 yards. The first step in correctly using TBR is to Practice, Practice, Practice.
12 For rifle users, RFL mode is comprised of three TBR functions: HOLD, MOA, and BAS. One of these modes must be selected. To select the desired function, navigate through the Quick Set Menu until RFL is reached (activate if necessary). While the RFL icon is highlighted and the word “SEt” is shown in the upper display, press and release POWER repeatedly to scroll through HOLD, MOA, and BAS respectively; press MODE when the desired function is displayed.
distance you will choose in a later mode. The upper display shows whether you should hold Hi or Low, and the number of inches or centimeters to be used for proper correction. For example, a reading of “Hi, 8” means you should hold 8 inches above the intended point of impact if measuring in yards. If measuring in meters, you should hold 8 centimeters above the intended point of impact. The lower display shows the line-ofsight distance to the target.

16 Function 2: Seven Rifle Ballistics Groups (RX-750 Model Only) TBR includes ballistics settings for seven rifle cartridge groups, which are displayed as A, B, C, AB, AC, BC, and ABC. For example, if your cartridge type is in Group A, the displayed reading will account for the shot angle and provide the proper distance for holdover purposes (see following chart). You must choose one of the seven groups, based on your cartridge and ballistics information.

22 Function 3: BOW MODE (RX-750 Model Only) This mode, when activated, works with TBR to provide the correct ballistics range for arrows. To activate, navigate through the Quick Set Menu by pressing mode until the BOW icon is displayed, then use the POWER button to turn it on/off. Selecting the BOW Mode automatically deactivates the Rifle Mode. The displayed range represents the ballistically equivalent horizontal distance to the target.
Only one group can be selected at a time. Selecting a new group deactivates all other groups. Most importantly, using BOW effectively means to Practice, Practice, Practice. Anytime you handle a firearm or bow, you are ultimately responsible for your projectile. For best results, measure the drop of your arrow at 40 yards when using your 20 yard aiming point. BOW 1.
24 Function 4: UNIT OUTPUT This mode is used to choose between yards and meters as the preferred unit of measure. TBR measurements are shown in the top portion of the display, line of sight measurements shown in the bottom portion of the display (RX-750 Model Only). To choose between yards and meters, navigate through the Quick Set Menu by pressing the MODE button until “Unit” is shown in the upper display. Press and release the POWER button to alternate between yards and meters.
Function 5: Last Target Mode (RX-750 Model Only) This mode is used to display the distance to the farthest object when more than one object may be read. Multiple objects will often return an average distance. Last Target Mode ensures an accurate reading on the farthest object. To activate Last Target mode, navigate through the Quick Set Menu by pressing the MODE button until the Last Target icon is shown in the left portion of the display. Press and release the POWER button to turn Last Target on/off.
26 Function 6: Line of sight Output This mode, when activated, provides the straight line distance to the target in the bottom portion of the display. To activate LOS, navigate through the Quick Set Menu by pressing the MODE button until the LOS icon is shown in the lower right portion of the display. Press and release the POWER button to turn LOS on/off. If you deactivate both the rifle mode and bow mode, LOS mode will automatically be activated.
27 Function 7: 3 selectable reticles This mode allows you to choose any one of the 3 preloaded reticles as the primary aiming point for the RX-600 / 750 digital laser rangefinders. To select a reticle, press Mode repeatedly until the current reticle is blinking. Press POWER repeatedly to scroll through the available reticles, then press MODE when the preferred reticle is shown. The reticle choices are as follows: Plus Point™ Plus PointTM: Ideal for varmints and other small targets.
Cleaning/Maintenance Blow away dust or debris on lenses, or use a soft lens brush (such as the one found on the Leupold LensPen). To remove fingerprints, water spots or tougher dirt, use a soft cotton cloth or the cleaning end of the Leupold LensPen. A lens tissue with lens cleaning fluid may be used for more stubborn dirt. Always apply cleaning fluid to the cleaning cloth, never directly to the lens. To insert a new battery, remove battery cover (shown in diagram on page 4) and remove exhausted battery.
