Introduction Congratulations! You have purchased a Leupold RX 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 Series rangefinder. To ensure top performance for the life of the product, please read these instructions before operating your RX-I, RX-II, RX-III, or RX-IV.
2 innovative and unique feature is True Ballistic Range (TBR ), which is available ™ on RX-II, RX-III, and RX-IV models. True Ballistic Range (TBR) is a marriage of laser ranging, inclinometer, and an advanced computerized ballistics program. The result is distance measuring precise within a yard, no matter the angle at which the laser is fired. Bullets and arrows travel in a ballistic arc, yet conventional rangefinders only provide a linear distance to your target.
MAXIMUM RANGE CONDITION RX-I RX-II RX-III RX-IV Reflective Target (yd) 750 750 1200 1500 Trees (yd) 600 600 800 900 Deer (yd) 500 500 700 800 Surface texture, color, size and shape of the target all affect the reflectivity, which in turn affects the maximum range of the instrument, to some degree. As a rule of thumb, brightly colored targets are much more reflective than darker targets. Tan game coats are more reflective (and thus provide a more solid reading) than a black roof.
4 Specifications The RX Series of digital laser rangefinders provides a variety of useful modes to tailor performance to the conditions you experience in the field. The particular models that feature each mode are identified on the following page.
Operation QUICK SET ROTARY MENU ™ *Display shown with all possible modes visible 5
6 RX-I -/+ RX -I & RX -II ™ RX -III & RX -IV ™ ™ Power Focus Mode Power -/+ RX-I Mode Set ™ Focus Battery Battery The RX-I and RX-II have two buttons: Power and Mode. The RX-III and RX-IV have three buttons: Power, Mode, and Set.
When you initially push the Power button, the unit is ready for scanning. When you first press the Mode button, the Quick Set Rotary Menu is prepared for ™ navigation. To set or activate a function, you must advance the mode selector to that function by pressing the Mode button until that function is flashing by itself. To lock in that function, press the Set button if using a RX-III or RX-IV; press the Power button if using a RX-I or RX-II.
8 FUNCTION 2: RAIN MODE The Rain Mode is used in rainy conditions and screens out false returns from raindrops or other atmospheric interference to provide an accurate range. FUNCTION 3: 1 TARGET MODE ST 1 Target Mode is used to display the range to the st closest object when more than one object may be hit by the beam. Multiple objects will often return an average distance. 1 Target Mode ensures an st accurate reading on the closest object.
FUNCTION 4: LAST TARGET MODE This mode is used to find the distance of 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. 1st Target Mode is automatically disabled while Last Target Mode is activated. FUNCTION 5: METER OUTPUT This mode displays both LOS (Line of Sight) and TBR ranges in meters, and will disable readings in yards or feet.
10 FUNCTION 6: FEET OUTPUT This mode displays both LOS (Line of Sight) and TBR ranges in feet, and will disable readings in yards or meters. TBR is displayed with one decimal place resolution in large numbers just above the reticle, LOS is displayed in small numbers above the angle readout (just below and to the right of the reticle). FUNCTION 7: YARDS OUTPUT This mode displays both LOS (Line of Sight) and TBR ranges in yards, and will disable readings in meters or feet.
FUNCTION 8: LINE OF SIGHT OUTPUT This mode, when activated, provides the straight line distance to the target. The output is displayed in smaller numbers just below and to the right of the reticle. NOTE: On the RX-I model, LOS is displayed in large numbers above the reticle (in the TBR position). FUNCTION 9: FAHRENHEIT OUTPUT When activated, this mode displays the air temperature in Fahrenheit. If Fahrenheit is activated, the Celsius Mode and LOS (Line of Sight) range will be disabled.
12 FUNCTION 10: CELSIUS OUTPUT When activated, this mode displays the air temperature in Celsius. If Celsius is activated, the Fahrenheit Mode and LOS (Line of Sight) range will be disabled. The output is displayed in smaller numbers just below and to the right of the reticle. FUNCTION 11: DIGITAL COMPASS MODE (RX-IV ONLY) When this mode is activated, the compass heading will be displayed in larger numbers above the reticle.
NOTE: Calibration of the compass must also be performed when the rangefinder is initially used and anytime it is moved to a new region — see Function 17 for calibration procedure. FUNCTION 12: DECLINATION ANGLE OUTPUT (RX-IV ONLY) This mode allows the user to manually set the declination angle that corrects the usual compass error between magnetic north and true north. Declination angle for your area can be found on the corner of any USGS topography map or on several Internet sites.
14 NOTE: Pressing “Set” continues to run through these settings until you press ”Mode” to move on. NOTE: Magnetic fields are constantly shifting on the Earth so declination angle may need to be reset every couple of years for maximum accuracy. FUNCTION 13: TRUE BALLISTIC RANGE 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 .
incredible accuracy, eliminating potential errors that could cause you to miscalculate your aiming point. The first step in correctly using TBR is Practice, Practice, Practice. Anytime you handle a firearm or bow, you are ultimately responsible for where your projectile ends up. The inclinometer output is shown below the LOS output or thermometer, whichever is enabled. The inclinometer output will be disabled when TBR is turned off.
16 options as you continue to press Mode. These options are HOLD (HOLd), MOA, and BAS (bAS). One of these modes needs to be selected before moving on to choosing your ballistic group in Function 15. To select ballistic groups for archery, TBR needs to be turned off and BOW turned on. HOLD will display your holdover for that target at that distance, which is also based upon the ballistic group and sight-in zero that you will choose in a later mode.
BAS will display the equivalent horizontal range. This is the range that you will want to shoot at, instead of the line of sight distance, which can be grossly off depending upon the angle of the shot. The display will read the equivalent horizontal range in the measurement you have chosen previously. NOTE: True Ballistic Range is available only in the RX-II, RX-III, and RX-IV models.

20 FUNCTION 14: BOW BALLISTIC GROUP This mode, when activated, works with TBR to provide the correct ballistic range for arrows. To select, be sure that TBR is turned off (follow instructions In Function 13), then select BOW by pressing Set or Power on RX-II. The range that displays will correspond to the target. It incorporates three different groups (Group A, B, or C) depending on the particular arrow drop. You must choose one of the three groups, based on your bow and arrow selection.
For best results, measure the drop of your arrow at 40 yards from your 20 yard aiming point. 1. Set up a small target point such as a two-inch circle of paper high on a large, safe background, such as a stack of bales backed by a solid backstop. Be sure to allow for three feet or more of drop to avoid arrow damage. 2. Shoot 2 or 3 arrows at the target from 40 yards, using your 20 yard pin on the small target. 3. Measure the distance from the small target to the center of the group of arrows. 4.
22 FUNCTIONS 15: SEVEN RIFLE BALLISTIC GROUPS TBR includes ballistic settings for seven cartridge groups that were specifically formulated for the three functions of TBR, which are displayed as A, B, C, AB, AC, BC, and ABC. For example, if your cartridge group is in Group A, the reading in function 15 will tell you what the distance is for holdover purposes, taking into account the shot angle (see following chart). You must choose one of the seven groups, based on your cartridge and ballistic information.

28 FUNCTION 16: MATCH 13 RETICLE SYSTEM ™ ™ By selecting this mode, any one of 13 preloaded reticles can be chosen as the primary aiming point for the RX rangefinder. To select a reticle, press Mode to scroll through the 13 reticle options. Press Power on RX-I and RX-II, or Set on RX-III and RX-IV, to select a reticle. The reticle choices are as follows: Plus Point : Ideal for varmints and other small targets. Small open center avoids coverage of very small or distant targets.
Bracket Circle Duplex : Provides bolder aiming for low-light/low-contrast situations. Brackets small game and 3D targets at 40 yards. Brackets a deer at 50 yards. Excellent for muzzleloaders. Bracket Square : Brackets an elk torso at 40 yards or a deer torso at 30 yards. Provides easy aiming on 3D targets and game for archers. German #4: A favorite of European hunters. Provides bold aiming and is free from obstructions in the upper half of the field of view.
30 FUNCTION 17: CALIBRATING THE COMPASS The RX models that feature the Compass Mode let you instantly determine the direction to, as well as the distance from, an object or animal. Before using the compass for the first time, or for the first time in a new geographic location, you must first calibrate it. 1. Press “Mode” and progress through the entire Quick Set Rotary Menu to the reticle options. 2. Select your reticle setting, press the “Set” button once, and “CAL” will display and flash. 3.
6. The calibration of the compass is now complete. See Function 12 on page 13 for instructions on setting declination angle. OTHER USEFUL FEATURES Clear Field Function: This allows you to clear the icons for modes, units, etc., ™ without deactivating the modes. To toggle Clear Field on and off — hold the “Power” button, then press the “Mode” button. Display Illumination: Provides sharp display contrast for optimum readability in low-light situations. RX-III and RX-IV only — Hold down the “Set” button.
32 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.
Helpful Hints for Using the Leupold RX Digital Laser Rangefinders HOW DO I ACTIVATE TRUE BALLISTIC RANGE (TBR)? Only available in RX-II, RX-III, and RX-IV. See Function 13 on page 14. Be sure to select the proper group for bows on page 20 or rifles on page 22. HOW DO I ACTIVATE SIMPLE LINE OF SIGHT (LOS) RANGE? Always on for RX-I model. To activate on RX-II, RX-III, and RX-IV models: follow the Quick Set Rotary Menu procedure (see page 5).
34 WHEN I SHOOT BASED ON THE TRUE BALLISTIC RANGE READOUT PROVIDED BY THE RANGEFINDER, THE PROJECTILE IS NOT HITTING THE TARGET. The first step in correctly using TBR is Practice, Practice, Practice. Anytime you handle a firearm or bow, you are ultimately responsible for where your projectile ends up. Be certain that if you’re shooting a bow that “BOW” is turned on. Be certain that if you’re shooting a rifle that “BOW” is turned off. Be certain you selected the correct ballistic groups (see pages 20-27).
The target may also be absorbing too much light (as in extremely dark-colored animals). Try ranging an object next to the target. Try turning on a mode that improves performance in your conditions such as Rain Mode when it is raining (see Function 2 on page 8). On RX-I and RX-II models, be certain you are not in the Quick Set Rotary Menu function. The unit will “time out”, and go into ranging mode from any mode setting in the Quick Set Rotary Menu after three or four seconds.
