Congratulations on your purchase of the Bushnell YARDAGE PRO LASER RANGEFINDER RIFLESCOPE. The YARDAGE PRO LASER RANGEFINDER RIFLESCOPE is a precision Laser Rangefinding optical instrument designed to provide many years of enjoyment. This booklet will help you achieve optimum performance by explaining its adjustments and features as well as how to care for this instrument. To ensure optimal performance and longevity, please read these instructions before using your YARDAGE PRO LASER RANGEFINDER RIFLESCOPE.

INTRODUCTION

GlassRangeAdjustall with one product! Bushnell has combined a premium 4-12x42mm riflescope with 3.5 inch eye-relief, a digitally advanced precision laser rangefinder providing distances from 30-800 yards, and a bullet drop compensator into one outstanding product. Fully Multi-Coated Optics deliver optimum brightness and color fidelity. The laser rangefinder is easily activated with an infrared remote trigger pad. Bullet-drop turrets eliminate hold-over guesswork. Simply install the turret that matches your caliber and load. When the range appears in the reticle, simply adjust it to the corresponding distance and hold dead-on. 100% waterproof / fogproof construction, Mil-dot reticle, standard and SCAN modes, and operates on 3-volt battery (included).
RANGING ACCURACY HOW DOES IT WORK?
Previously, you had to estimate distance to a target by means of a riflescope reticle, calculating postto-post intervals with more or less exact results. Now you can measure the exact distance to a target with dead-on precision instantaneously. With the YARDAGE PRO LASER RANGEFINDER RIFLESCOPE, you just activate the unit by pressing the infrared remote and the laser rangefinder emits invisible, eye safe, infrared energy pulses. Sophisticated digital technology instantaneously calculates distances by measuring the time it takes for each pulse to travel from the rangefinder, to the target, and back resulting in instantaneous and accurate readings within the field-of-view.
The ranging accuracy of the YARDAGE PRO LASER RANGEFINDER RIFLESCOPE is plus or minus one yard / meter under most circumstances. The maximum range of the instrument depends on the reflectivity of the target. The maximum distance under optimal conditions is 800 yards / 732 meters. Note: You will get both longer and shorter maximum distances depending on the reflective properties of the particular target and the environmental conditions at the time the distance of an object is being measured. The color, surface finish, size and shape of the target all affect reflectivity and range. The brighter the color, the longer the range. White is highly reflective, for example, and allows longer ranges than the color black, which is the least reflective color. A shiny finish provides more range than a dull one. A small target is more difficult to range than a larger target. The angle to the target also has an effect. Shooting to a target at a 90 degree angle (where the target surface is perpendicular to the flight path of the emitted energy pulses) provides good range while a steep angle on the other hand, provides limited ranging. In addition, lighting conditions (e.g. the amount of sunlight) will affect the ranging capabilities of the unit. The less light (e.g. overcast skies) the farther the units maximum range will be. Conversely, very sunny days will decrease the units maximum range.

GETTING STARTED

INSERTING THE BATTERY

Remove the battery compartment cover (Figure 1.1) by loosening the battery compartment locking screw with a coin. Insert one CR-2 3-volt lithium battery with polarity (+ and -) as indicated inside the compartment. Replace the battery compartment cover and secure by tightening the battery compartment locking screw. Note: The battery will provide approximately 5,000 ranges. Remove the battery from the riflescope if it is not going to be used for longer than one month.

Battery: Full Half

OPERATIONAL SUMMARY
Battery: It is recommended that the battery be replaced.
WARNING: This laser rangefinder riflescope should never be used as a substitute for a binocular, spotting scope, or measuring device only, as it may result in your inadvertently pointing the gun at another person. Before using this device, always remember it is mounted on a firearm and all firearm safety precautions apply. When handling firearms, always keep the muzzle pointed in a safe direction. While looking through the riflescope, always depress the main power button (Figure 1.2) once to turn the unit on. You can now use the infrared remote trigger pad (Figure 2) to activate the laser and
in-view LED display (Figure 3). NOTE: If the unit has not been used for two or more hours, the main power button will need to first be depressed in order to use the infrared remote trigger pad. Aim the laser rangefinder at a target at least 30 yards away, depress and hold the power button or infrared remote trigger pad down until range reading is displayed. Release the power button or remote trigger pad. Note: Once activated, the laser rangefinders LED will remain active and display the last distance measurement for 8 seconds. You can depress the power button / remote trigger pad again at any time to distance to a new target. Once the device is on and the power button or remote trigger pad is held down for over 2 seconds, the device transitions to SCAN mode. This mode allows the range to be continuously updated for as the power button / remote trigger pad is depressed. As with any laser device, it is not recommended to directly view the emissions for long periods of time with magnified lenses. If three horizontal line (---) appear (Figure 4), this indicates that the unit could not measure the distance properly for a number of reasons (i.e. target too far away, intense reflection, unit not aimed directly at target, etc). Three lines, one on top of another in a vertical arrangement (Figure 5) will appear indicating that the unit is measuring and the distance in yards or meters will appear (Figure 6).
If the unit of measure appears in Yards (Y) and you would like to switch the Meters (M), simply press the Yards / Meters button (Figure 1.3) portion of the main POWER button. Conversely, when the readout is in meters, it can be switched to yards by the same process.
INFRARED REMOTE TRIGGER PAD
An infrared remote trigger pad (Figure 2) is included with the product. It was designed to attach to the forearm of the rifle and will work for either right or left hand shooters. It allows the user to maintain a stable shooting position while operating the laser rangefinder. The red triangle on the remote trigger must be faced toward the shooter and be placed on the forearm of the rifle for it to work properly and needs to be positioned within the 6 inch space outlined in Figure 7 so that it can properly communicate with the infrared sensor (Figure 1.6). The remote trigger operates on one CR2016 watch battery. To replace this battery, open the cover with a small screw driver, remove existing battery and replace with a new one and replace cover.

NOTE: The electronics are set to automatically shut off after two hours of inactivity. Therefore, to re-instate use of the infrared remote trigger pad, the main power button (Figure 1.2) must first be depressed.

EYEPIECE FOCUSING

When still-hunting or stalking game, a variable scope should be set to the lowest power. You then have the widest field of view for quick shots at close range. Higher powers should be reserved for precise long-range shots. WARNING: This laser rangefinder riflescope should never be used as a substitute for a binocular, spotting scope, or measuring device only, as it may result in your inadvertently pointing the gun at another person. Before using this device, always remember it is mounted on a firearm and all firearm safety precautions apply. When handling firearms, always keep the muzzle pointed in a safe direction.

MOUNTING (See Figure 8)

This adjusts the focus so that the reticle (cross hairs) appears sharp to your eyes. All Bushnell laser rangefinder riflescopes are focused at the factory for 20/20 or corrected vision. If the reticle appears sharp, no adjustment is needed. If the reticle appears unsharp, adjust as follows. The FAST FOCUS eyepiece (Figure 1.4) is designed to provide a precise fast focus. Simply look at a distant object for several seconds without using your scope. Then, shift your vision quickly, looking though the scope at a plain background. Turn the fast-focus eyepiece clockwise or counter clockwise until the reticle pattern is sharp and clear. WARNING: Never look at the sun through the laser rangefinder riflescope (or any other optical instrument). It may permanently damage your eye.
VARIABLE POWER ADJUSTMENTS
To achieve the best accuracy from your rifle, your Bushnell scope must be mounted properly. (We strongly recommend that those unfamiliar with proper procedures have the scope mounted by a qualified gunsmith). Should you decide to mount it yourself: Use the enclosed mount system. The mounts are made to fit the weaver style dovetail system. Before mounting the scope, determine approximately where you would like it to be on the rifle. The slots on the bottom of the riflescope allow you great flexibility in mounting the scope forward or to the rear. WARNING: If the scope is not mounted far enough forward, its rearward motion may injure the shooter when the rifle recoils.
To change magnification, simply rotate the Power Change Ring (Figure 1.5) to align the desired number on the power scale with the Red Arrow Indicator.

The front mount has a key that fits into the slots on the riflescope dovetail. Choose the appropriate slot and attach the front mount securely with the two scope dovetail screws. The rear mount does not have a key allowing it to slide forward or backward on the dovetail of the riflescope to fit. Loosely place it on the riflescope dovetail leave the two screws loose for now so that the mount can slide on the dovetail. Place the riflescope on the rifle, fitting the front and rear mounts to the weaver bases. Space the mounts as far apart as possible to provide stability. Lightly tighten the screws holding the mounts to the weaver bases. Now look through the scope in your normal shooting position. Adjust the scope (either forward or backward with the mounts) until you find the furthest point forward (to insure maximum eye relief ) that allows you to see a full field of view. Tighten the mounting screws as tight as possible. Key
ELEVATION AND WINDAGE ADJUSTMENT
Your Bushnell YARDAGE PRO LASER RANGEFINDER RIFLESCOPE features finger-adjustable, audible-click elevation and windage adjustments. If the point of impact of the bullet deviates from the aiming point, then adjustment of the windage and elevation must be made. To adjust windage, remove the threaded cap from the Windage Adjustment (Figure 1.7). Grasp the knob and turn it in the appropriate L (Left) and/or R (Right) direction indicated by the arrows. Each click or increment on the adjustment scale ring will change the bullet impact by 1/4 Minute of Angle. 1/4 MOA corresponds to 1/4 inch at 100 yards, 1/2 inch at 200 yards, 3/4 inch at 300 yards and so on.
RESETTING THE ADJUSTMENT SCALE RING
This step is not necessary, but, for future reference, you may want to realign the zero marks on the Adjustment Scale Rings with the index dots. - Using a coin, remove the center screw from the windage or elevation control. Lift the turret up being careful not to rotate it. - Position the turret to zero, or where you would like it to be. - Replace and tighten the center screw, making sure you do not rotate the turret.

Bore sighting is a preliminary procedure to achieve proper alignment of the scope with the rifle bore. It is best done using a Bushnell Bore Sighter. If a bore sighter is not available, it can be done as follows: Remove the bolt and sight through the gun barrel at a 100 yard target. Then sight through the scope and bring the crosshairs to the same point on the target.

- Remove the elevation cap. If the standard elevation turret is not installed, remove the BDC turret and install it. This is done by using a coin to unscrew the retaining screw in the center of the turret. Grasp knurl at top of the Turret and lift upward, disengaging turret from the elevation adjustment pin. Reverse to install a new turret. - Sight-in the rifle, firing a group of at least three shots at 100 yard target. Note the relationship of the center of group to the center or the target. Rotate the turret the required number of clicks to make the necessary point of impact move. Follow with the windage adjustment to bring shots to center of target. Fire another group to see if proper adjustment has been made. Repeat as necessary until center of group is in center of target. - Once the rifle is sighted-in at 100 yds, you may install the proper BDC Turret for your caliber and bullet weight (see SELECT PROPER TURRET below). (NOTE: When the selected BDC turret is installed, the elevation cap cannot be used. If the standard elevation turret is installed, the cap can be threaded onto the scope).

own distance markings fit any cartridge not covered. From the Ballistic Chart below (or the complete charts on the CD), select the proper turret for use with your caliber and bullet weight combination. Example: You have a.300 WSM and are shooting the following Winchester brand load: 180 gr. Ballistic Silver Tip bullet at 3010 FPS muzzle velocity. This combination falls under Ballistic group F, so you would use the turret marked F in either yards or meters.

What if your caliber is not listed?
While we have taken great care to include as many calibers and brand names in our ballistic tables, new loads are always being developed. In additon, some shooters load their own ammunition with unique ballistic characteristics. If you cannot find your load in the ballistic tables, you can still use the BDC feature.

Option 1:

Each riflescope comes complete with seventeen interchangeable turrets. Eight of these turrets are calibrated with distance in yards markings and eight for meters covering most popular factory cartridges. The seventeeth turret has no distance calibration but is provided so that you may make your
As above, sight in your rifle at 100 yds with the standard turret. Then shoot the rifle, without adjusting the riflescope, at 300 yds. Measure the bullet drop from the point of aim. Using this drop, select the ballistic group from below. If you will be shooting at longer distances then you may want to check the bullet drop at 500 yds. Because there is enormous variation in rifle barrels, chambers, and hand loads, you should thoroughly test the ballistic setting before actual hunting. You may need to move up or down one group depending upon your tests.

Option 2:

Included with the marked turrets is a blank turret. After your rifle is sighted in at 100 yds, replace the standard turret with the blank turret. Without adjusting the elevation, shoot the rifle at various distances up to the
maximum distance needed. Measure the bullet drop at each distance and then convert the drop into moa. Multiply the moa by 4. Using this number, count the number of tick marks on the dial and mark the distance. If Bullet Drop is: Use: A B C D E F G H 25-31 inches 20-25 inches 16-20 inches 13-16 inches 12-13 inches 10-12 inches 8-10 inches 63-79 cm 50-63 cm 40-50 cm 34-40 cm 30-34 cm 25-30 cm 20-25 cm 114-146 inches 88-114 inches 72-88 inches 61-72 inches 55-61 inches 47-55 inches 39-47 inches 291-370 cm 225-291 cm 182-225 cm 155-182 cm 139-155 cm 119-139 cm 99-119 cm @300 yds @300 m @500 yds @500 m

need the mil dot for measuring distance, but is useful for precise leads for moving targets and exact compensation for shooting in a crosswind. There are certain situations that may not allow one enough time to range to an animal, and having the mil-dot reticle is second alternative in measuring distance. The middle of this reticle contains four evenly spaced mil-dots arrayed outward vertically and horizontally from the center. Actually, because the very center dot was left out to allow clear aiming, the reticle represents five mils in any direction. One mil is the space from center-dot to center-dot. One-half and one-quarter mils are easy to estimate mentally; with practice, you can measure tenths of mils for the most exact ranging.
RANGING WITH YOUR MIL-DOT RETICLE
Less than 8 inches Less than 20 cm Less than 39 inches Less than 99 cm
The mil is an angular measurement a milliradianwhich equals almost precisely one yard at 1000 yards, or one meter at 1000 meters. This proportional relationship makes possible a simple formula to compute distances: The Measured Objects Width Or Height In Yards x 1000 Objects Width Or Height In Mils = Range In Yards
Example: Suppose you have a bullet drop of 9 inches at 300 yds. This is a drop of 3 moa. Since the clicks are moa, the drop for 300 yds would be 12 tick marks.

USING MIL DOTS

Your new Bushnell YARDAGE PRO LASER RANGEFINDER RIFLESCOPE contains a mil-dot reticle. Since the riflescope already contains an integrated laser rangefinder, it is not likely that you will
This formula works equally well with meters, but dont mix meters and yards: Measure the object in yards to find the distance in yards, use meters to yield distances in meters.
Looking through your scope at the synchronized magnification setting, select an object at the distance you want to range -- an object whose width or height you know or can estimate accurately. Man-made objects of uniform size, such as fence posts, are best, but any object of known dimensions will do. Measure the objects height or width carefully in mils, compute it according to the formula and you will find its range. Support your rifle and be precise when measuring objects; any measuring error causes an error in the computed range. Equally, incorrectly estimating the object size results in a proportional range error. Heres an example: A coyote is sunning himself in a snowfield beside a fencepost; having crossed the fence earlier, you know that the post is four feet high, or 1.33 yards. The fencepost measures 2.5 mils in your reticle. 1.33 yards x 1000 2.5 mils = 1330 2.5 = 532 Yards

Its easy to measure in half-mils or even quarter-mils but with practice you can measure tenths of a mil. 2.6x - Object measures half as large as 12x, so calculate the distance, then divide by half. 3.12x - Synchronized setting for this mil-dot reticle. Calculate as normal.

MAINTENANCE

Since this is a variable power scope and the reticle stays the same size no matter the magnification, it must be set at the 12x index dot to synchronize the mil-dot size for ranging.
CALCULATING HOLDS FOR WIND AND MOVING TARGETS
Your horizontal mil dots provide a precise way of holding for crosswinds and target movement. Just look in your cartridges wind drift and moving target tables to determine the exact holds for different distances. The accompanying table lists one-mil widths from 100 to 600 yards, so you can calculate how many mils to hold right or left when firing in a crosswind, or engaging a moving target.
Your Bushnell YARDAGE PRO LASER RANGEFINDER RIFLESCOPE, though amazingly tough, is a precision instrument that deserves reasonably cautious care.
1. When cleaning the lenses, first blow away any dry dirt and dust, or use a soft lens brush. Fingerprints and lubricants can be wiped off with lens tissue, or a soft clean cloth, moistened with lens cleaning fluid. WARNING: Unnecessary rubbing or use of a course cloth may cause permanent damage to the lens coatings. 2.All moving parts of the scope are permanently lubricated. Do not try to lubricate them. 3.No maintenance is needed on the scopes outer surface, except to occasionally wipe off dirt or fingerprints with a soft cloth. 4.Use lens covers whenever it is convenient.

STORAGE

TROUBLE SHOOTING TABLE
If unit does not turn on - LED does not illuminate: Depress main power button on the riflescope first, and then the infrared remote switch. Check and if necessary, replace battery. Check battery within the infrared remote switch, and if necessary, replace its battery. If unit powers down (display goes blank when attempting to power the laser): The battery is either weak or low quality. Replace the battery with a good quality lithium battery. The last range reading does not need to be cleared before ranging another target. Simply aim at the new target using the reticle, depress the power button and hold until new range reading is displayed. If target range cannot be obtained: Make sure LED is illuminated. Make sure that the power button is being depressed Make sure that nothing, such as your hand or finger, is blocking the objective lenses (lenses closest to the target) that emit and receive the laser pulses. Make sure unit is held steady while depressing power button. Specifications, instructions, and the operation of these products are subject to change without notice. This product complies with CFR 21 1040.10. Class 1 laser product.

Remove the battery from the riflescope if it is not going to be used for longer than one month. Avoid storing the scope in hot places, such as the passenger compartment of a vehicle on a hot day. The high temperature could adversely affect the lubricants and sealants. A vehicles trunk, a gun cabinet or a closet is preferable. Never leave the scope where direct sunlight can enter either the objective or the eyepiece lens. Damage may result from the concentration (burning glass effect) of the suns rays.

Bushnell Yardage Pro 4-12x42 Laser Rangefinder Laser rangefinder riflescope (204124) Congratulations on your purchase of the Bushnell YARDAGE PRO LASER RANGEFINDER RIFLESCOPE. The YARDAGE PRO LASER RANGEFINDER RIFLESCOPE is a precision Laser Rangefinding optical instrument designed to provide many years of enjoyment. This booklet will help you achieve optimum performance by explaining its adjustments and features as well as how to care for this instrument. To ensure optimal performance and longevity, please read these instructions before using your YARDAGE PRO LASER RANGEFINDER RIFLESCOPE.

INTRODUCTION

GlassRangeAdjust---all with one product! Bushnell has combined a premium 4-12x42mm riflescope with 3.5 inch eye-relief, a digitally advanced precision laser rangefinder providing distances from 30-800 yards, and a bullet drop compensator into one outstanding product. Fully Multi-Coated Optics deliver optimum brightness and color fidelity. The laser rangefinder is easily activated with an infrared remote trigger pad. Bullet-drop turrets eliminate hold-over guesswork. Simply install the turret that matches your caliber and load. When the range appears in the reticle, simply adjust it to the corresponding distance and hold dead-on. 100% waterproof / fogproof construction, Mil-dot reticle, +- one yard accuracy, standard and SCAN modes, and operates on 3-volt battery (included).

HOW DOES IT WORK?

Previously, you had to estimate distance to a target by means of a riflescope reticle, calculating postto-post intervals with more or less exact results. Now you can measure the exact distance to a target with dead-on precision instantaneously. With the YARDAGE PRO LASER RANGEFINDER RIFLESCOPE, you just activate the unit by pressing the infrared remote and the laser rangefinder emits invisible, eye safe, infrared energy pulses. Sophisticated digital technology instantaneously calculates distances by measuring the time it takes for each pulse to travel from the rangefinder, to the target, and back resulting in instantaneous and accurate readings within the field-of-view.

RANGING ACCURACY

The ranging accuracy of the YARDAGE PRO LASER RANGEFINDER RIFLESCOPE is plus or minus one yard / meter under most circumstances. The maximum range of the instrument depends on the reflectivity of the target. The maximum distance under optimal conditions is 800 yards / 732 meters. Note: You will get both longer and shorter maximum distances depending on the reflective properties of the particular target and the environmental conditions at the time the distance of an object is being measured. The color, surface finish, size and shape of the target all affect reflectivity and range. The brighter the color, the longer the range. White is highly reflective, for example, and allows longer ranges than the color black, which is the least reflective color. A shiny finish provides more range than a dull one. A small target is more difficult to range than a larger target. The angle to the target also has an effect. Shooting to a target at a 90 degree angle (where the target surface is perpendicular to the flight path of the emitted energy pulses) provides good range while a steep angle on the other hand, provides
limited ranging. In addition, lighting conditions (e.g. the amount of sunlight) will affect the ranging capabilities of the unit. The less light (e.g. overcast skies) the farther the units maximum range will be. Conversely, very sunny days will decrease the units maximum range. (Figure 1)

OPERATIONAL SUMMARY
Battery: It is recommended that the battery be replaced.
WARNING: This laser rangefinder riflescope should never be used as a substitute for a binocular, spotting scope, or measuring device only, as it may result in your inadvertently pointing the gun at another person. Before using this device, always remember it is mounted on a firearm and all firearm safety precautions apply. When handling firearms, always keep the muzzle pointed in a safe direction. While looking through the riflescope, always depress the main power button (Figure 1.2) once to turn the unit on. You can now use the infrared remote trigger pad (Figure 2) to activate the laser and in6
view LED display (Figure 3). NOTE: If the unit has not been used for two or more hours, the main power button will need to first be depressed in order to use the infrared remote trigger pad. Aim the laser rangefinder at a target at least 30 yards away, depress and hold the power button or infrared remote trigger pad down until range reading is displayed. Release the power button or remote trigger pad. Note: Once activated, the laser rangefinders LED will remain active and display the last distance measurement for 8 seconds. You can depress the power button / remote trigger pad again at any time to distance to a new target. Once the device is on and the power button or remote trigger pad is held down for over 2 seconds, the device transitions to SCAN mode. This mode allows the range to be continuously updated for as the power button / remote trigger pad is depressed. As with any laser device, it is not recommended to directly view the emissions for long periods of time with magnified lenses. If three horizontal line (---) appear (Figure 4), this indicates that the unit could not measure the distance properly for a number of reasons (i.e. target too far away, intense reflection, unit not aimed directly at target, etc). Three lines, one on top of another in a vertical arrangement (Figure 5) will appear indicating that the unit is measuring and the distance in yards or meters will appear (Figure 6).

(Figure 6)
If the unit of measure appears in Yards (Y) and you would like to switch the Meters (M), simply press the Yards / Meters button (Figure 1.3) portion of the main POWER button. Conversely, when the readout is in meters, it can be switched to yards by the same process.
INFRARED REMOTE TRIGGER PAD
An infrared remote trigger pad (Figure 2) is included with the product. It was designed to attach to the forearm of the rifle and will work for either right or left hand shooters. It allows the user to maintain a stable shooting position while operating the laser rangefinder. The red triangle on the remote trigger must be faced toward the shooter and be placed on the forearm of the rifle for it to work properly and needs to be positioned within the 6 inch space outlined in Figure 7 so that it can properly communicate with the infrared sensor (Figure 1.6). The remote trigger operates on one CR2016 watch battery. To replace this battery, open the cover with a small screw driver, remove existing battery and replace with a new one and replace cover. (Figure 7) 6 inches / 152mm
NOTE: The electronics are set to automatically shut off after two hours of inactivity. Therefore, to re-instate use of the infrared remote trigger pad, the main power button (Figure 1.2) must first be depressed.

EYEPIECE FOCUSING

This adjusts the focus so that the reticle (cross hairs) appears sharp to your eyes. All Bushnell laser rangefinder riflescopes are focused at the factory for 20/20 or corrected vision. If the reticle appears sharp, no adjustment is needed. If the reticle appears unsharp, adjust as follows. The FAST FOCUS eyepiece (Figure 1.4) is designed to provide a precise fast focus. Simply look at a distant object for several seconds without using your scope. Then, shift your vision quickly, looking though the scope at a plain background. Turn the fast-focus eyepiece clockwise or counter clockwise until the reticle pattern is sharp and clear. WARNING: Never look at the sun through the laser rangefinder riflescope (or any other optical instrument). It may permanently damage your eye.

VARIABLE POWER ADJUSTMENTS
To change magnification, simply rotate the Power Change Ring (Figure 1.5) to align the desired number on the power scale with the Red Arrow Indicator.
When still-hunting or stalking game, a variable scope should be set to the lowest power. You then have the widest field of view for quick shots at close range. Higher powers should be reserved for precise long-range shots. WARNING: This laser rangefinder riflescope should never be used as a substitute for a binocular, spotting scope, or measuring device only, as it may result in your inadvertently pointing the gun at another person. Before using this device, always remember it is mounted on a firearm and all firearm safety precautions apply. When handling firearms, always keep the muzzle pointed in a safe direction.

MOUNTING (See Figure 8)

To achieve the best accuracy from your rifle, your Bushnell scope must be mounted properly. (We strongly recommend that those unfamiliar with proper procedures have the scope mounted by a qualified gunsmith). Should you decide to mount it yourself: Use the enclosed mount system. The mounts are made to fit the weaver style dovetail system. Before mounting the scope, determine approximately where you would like it to be on the rifle. The slots on the bottom of the riflescope allow you great flexibility in mounting the scope forward or to the rear. WARNING: If the scope is not mounted far enough forward, its rearward motion may injure the shooter when the rifle recoils.
The front mount has a key that fits into the slots on the riflescope dovetail. Choose the appropriate slot and attach the front mount securely with the two scope dovetail screws. The rear mount does not have a key allowing it to slide forward or backward on the dovetail of the riflescope to fit. Loosely place it on the riflescope dovetail leave the two screws loose for now so that the mount can slide on the dovetail. Place the riflescope on the rifle, fitting the front and rear mounts to the weaver bases. Space the mounts as far apart as possible to provide stability. Lightly tighten the screws holding the mounts to the weaver bases. Now look through the scope in your normal shooting position. Adjust the scope (either forward or backward with the mounts) until you find the furthest point forward (to insure maximum eye relief ) that allows you to see a full field of view. Tighten the mounting screws as tight as possible. Key

ELEVATION AND WINDAGE ADJUSTMENT
Your Bushnell YARDAGE PRO LASER RANGEFINDER RIFLESCOPE features finger-adjustable, audible-click elevation and windage adjustments. If the point of impact of the bullet deviates from the aiming point, then adjustment of the windage and elevation must be made. To adjust windage, remove the threaded cap from the Windage Adjustment (Figure 1.7). Grasp the knob and turn it in the appropriate L (Left) and/or R (Right) direction indicated by the arrows. Each click or increment on the adjustment scale ring will change the bullet impact by 1/4 Minute of Angle. 1/4 MOA corresponds to 1/4 inch at 100 yards, 1/2 inch at 200 yards, 3/4 inch at 300 yards and so on.
RESETTING THE ADJUSTMENT SCALE RING
This step is not necessary, but, for future reference, you may want to realign the zero marks on the Adjustment Scale Rings with the index dots. - Using a coin, remove the center screw from the windage or elevation control. Lift the turret up being careful not to rotate it. - Position the turret to zero, or where you would like it to be. - Replace and tighten the center screw, making sure you do not rotate the turret.

BORE SIGHTING

Bore sighting is a preliminary procedure to achieve proper alignment of the scope with the rifle bore. It is best done using a Bushnell Bore Sighter. If a bore sighter is not available, it can be done as follows: Remove the bolt and sight through the gun barrel at a 100 yard target. Then sight through the scope and bring the crosshairs to the same point on the target.
SIGHTING IN RIFLE AT THE RANGE
- Remove the elevation cap. If the standard elevation turret is not installed, remove the BDC turret and install it. This is done by using a coin to unscrew the retaining screw in the center of the turret. Grasp knurl at top of the Turret and lift upward, disengaging turret from the elevation adjustment pin. Reverse to install a new turret. - Sight-in the rifle, firing a group of at least three shots at 100 yard target. Note the relationship of the center of group to the center or the target. Rotate the turret the required number of clicks to make the necessary point of impact move. Follow with the windage adjustment to bring shots to center of target. Fire another group to see if proper adjustment has been made. Repeat as necessary until center of group is in center of target. - Once the rifle is sighted-in at 100 yds, you may install the proper BDC Turret for your caliber and bullet weight (see SELECT PROPER TURRET below). (NOTE: When the selected BDC turret is installed, the elevation cap cannot be used. If the standard elevation turret is installed, the cap can be threaded onto the scope).

SELECTING THE PROPER TURRET

D D D F F F F E F H H H

Each riflescope comes complete with seventeen interchangeable turrets. Eight of these turrets are calibrated with distance in yards markings and eight for meters covering most popular factory cartridges. The seventeeth turret has no distance calibration but is provided so that you may make your
own distance markings fit any cartridge not covered. From the Ballistic Chart below (or the complete charts on the CD), select the proper turret for use with your caliber and bullet weight combination. Example: You have a.300 WSM and are shooting the following Winchester brand load: 180 gr. Ballistic Silver Tip bullet at 3010 FPS muzzle velocity. This combination falls under Ballistic group F, so you would use the turret marked F in either yards or meters.
What if your caliber is not listed?
While we have taken great care to include as many calibers and brand names in our ballistic tables, new loads are always being developed. In additon, some shooters load their own ammunition with unique ballistic characteristics. If you cannot find your load in the ballistic tables, you can still use the BDC feature.

Option 1:

As above, sight in your rifle at 100 yds with the standard turret. Then shoot the rifle, without adjusting the riflescope, at 300 yds. Measure the bullet drop from the point of aim. Using this drop, select the ballistic group from below. If you will be shooting at longer distances then you may want to check the bullet drop at 500 yds. Because there is enormous variation in rifle barrels, chambers, and hand loads, you should thoroughly test the ballistic setting before actual hunting. You may need to move up or down one group depending upon your tests.

Option 2:

Included with the marked turrets is a blank turret. After your rifle is sighted in at 100 yds, replace the standard turret with the blank turret. Without adjusting the elevation, shoot the rifle at various distances up to the
maximum distance needed. Measure the bullet drop at each distance and then convert the drop into moa. Multiply the moa by 4. Using this number, count the number of tick marks on the dial and mark the distance. If Bullet Drop is: Use: A B C D E F G H 25-31 inches 20-25 inches 16-20 inches 13-16 inches 12-13 inches 10-12 inches 8-10 inches 63-79 cm 50-63 cm 40-50 cm 34-40 cm 30-34 cm 25-30 cm 20-25 cm 114-146 inches 88-114 inches 72-88 inches 61-72 inches 55-61 inches 47-55 inches 39-47 inches 291-370 cm 225-291 cm 182-225 cm 155-182 cm 139-155 cm 119-139 cm 99-119 cm @300 yds @300 m @500 yds @500 m
Less than 8 inches Less than 20 cm Less than 39 inches Less than 99 cm
Example: Suppose you have a bullet drop of 9 inches at 300 yds. This is a drop of 3 moa. Since the clicks are moa, the drop for 300 yds would be 12 tick marks.

USING MIL DOTS

Your new Bushnell YARDAGE PRO LASER RANGEFINDER RIFLESCOPE contains a mil-dot reticle. Since the riflescope already contains an integrated laser rangefinder, it is not likely that you will
need the mil dot for measuring distance, but is useful for precise leads for moving targets and exact compensation for shooting in a crosswind. There are certain situations that may not allow one enough time to range to an animal, and having the mil-dot reticle is second alternative in measuring distance. The middle of this reticle contains four evenly spaced mil-dots arrayed outward vertically and horizontally from the center. Actually, because the very center dot was left out to allow clear aiming, the reticle represents five mils in any direction. One mil is the space from center-dot to center-dot. One-half and one-quarter mils are easy to estimate mentally; with practice, you can measure tenths of mils for the most exact ranging.

RANGING WITH YOUR MIL-DOT RETICLE
The mil is an angular measurement a milliradian -- which equals almost precisely one yard at 1000 yards, or one meter at 1000 meters. This proportional relationship makes possible a simple formula to compute distances: The Measured Objects Width Or Height In Yards x 1000 Objects Width Or Height In Mils = Range In Yards
This formula works equally well with meters, but dont mix meters and yards: Measure the object in yards to find the distance in yards, use meters to yield distances in meters.
Looking through your scope at the synchronized magnification setting, select an object at the distance you want to range -- an object whose width or height you know or can estimate accurately. Man-made objects of uniform size, such as fence posts, are best, but any object of known dimensions will do. Measure the objects height or width carefully in mils, compute it according to the formula and you will find its range. Support your rifle and be precise when measuring objects; any measuring error causes an error in the computed range. Equally, incorrectly estimating the object size results in a proportional range error. Heres an example: A coyote is sunning himself in a snowfield beside a fencepost; having crossed the fence earlier, you know that the post is four feet high, or 1.33 yards. The fencepost measures 2.5 mils in your reticle. 1.33 yards x 1000 2.5 mils = 1330 2.5 = 532 Yards
Since this is a variable power scope and the reticle stays the same size no matter the magnification, it must be set at the 12x index dot to synchronize the mil-dot size for ranging.
CALCULATING HOLDS FOR WIND AND MOVING TARGETS
Your horizontal mil dots provide a precise way of holding for crosswinds and target movement. Just look in your cartridges wind drift and moving target tables to determine the exact holds for different distances. The accompanying table lists one-mil widths from 100 to 600 yards, so you can calculate how many mils to hold right or left when firing in a crosswind, or engaging a moving target.
MIL WIDTH FOR WIND AND MOVING TARGET LEADS
Distance One Mil at This Distance (Inches) 100 Yards 3.6 (0.1 Yard) 200 Yards 7.2 (0.2 Yard) 300 Yards 10.8 (0.3 Yard) 400 Yards 14.4 (0.4 Yard) 500 Yards 18.0 (0.5 Yard) 600 Yards 21.6 (0.6 Yard)
1.One mil is the distance between center of dots. Its easy to measure in half-mils or even quarter-mils but with practice you can measure tenths of a mil. 2.6x - Object measures half as large as 12x, so calculate the distance, then divide by half. 3.12x - Synchronized setting for this mil-dot reticle. Calculate as normal.

MAINTENANCE

Your Bushnell YARDAGE PRO LASER RANGEFINDER RIFLESCOPE, though amazingly tough, is a precision instrument that deserves reasonably cautious care.
1. When cleaning the lenses, first blow away any dry dirt and dust, or use a soft lens brush. Fingerprints and lubricants can be wiped off with lens tissue, or a soft clean cloth, moistened with lens cleaning fluid. WARNING: Unnecessary rubbing or use of a course cloth may cause permanent damage to the lens coatings. 2.All moving parts of the scope are permanently lubricated. Do not try to lubricate them. 3.No maintenance is needed on the scopes outer surface, except to occasionally wipe off dirt or fingerprints with a soft cloth. 4.Use lens covers whenever it is convenient.

STORAGE

Remove the battery from the riflescope if it is not going to be used for longer than one month. Avoid storing the scope in hot places, such as the passenger compartment of a vehicle on a hot day. The high temperature could adversely affect the lubricants and sealants. A vehicles trunk, a gun cabinet or a closet is preferable. Never leave the scope where direct sunlight can enter either the objective or the eyepiece lens. Damage may result from the concentration (burning glass effect) of the suns rays.
