HOW IT WORKS  
The Cabela’s VLR II by Bushnell emits invisible, eye safe, infrared energy pulses. The Advanced Digital  
microprocessor and ASIC chip (Application-Specific Integrated Circuit) results in instantaneous and  
accurate readings every time. 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.  
RANGING ACCURACY  
The ranging accuracy of the VLR II 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 for  
most objects is 600 yards / 549 meters while for highly reflective objects the maximum is 999 yards /  
914 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 unit’s maximum range will be. Conversely, very sunny  
days will decrease the unit’s maximum range.

GETTING STARTED  
INSERTING THE BATTERY  
Remove the battery cap with a coin by rotating the cap counter clockwise and insert a 3-volt lithium  
battery into the compartment positive end first, then replace the battery cap.  
NOTE: It is recommended that the battery be replaced at least once every 12 months.  
Low Battery Indicator: If the “  
” is displayed within the in-view readout, this means “low battery” or  
battery charge is getting low and the 3-volt lithium battery should be replaced.

ADJUSTING THE EYEPIECE  
Your VLR II is constructed with an adjustable eyepiece (+/- 2 Diopter Adjustment) that allows one to focus  
the LCD display relative to the image. For users without eyeglasses, simply rotate the eyepiece until the  
reticle and object distanced to are in focus to your eye. If you wear glasses, place the eyepiece up to  
your glasses and rotate the eyepiece until the reticle and object distanced to are in focus to your eye.  
OPERATIONAL SUMMARY  
While looking through the 5x eyepiece, depress the power button once to activate the in-view Liquid  
Crystal Display (LCD). Place the aiming circle (located in the center of the field of view) upon a target at  
least 5 yards away, depress and hold the power button down until the range reading is displayed near  
the bottom of the in-view display. Crosshairs surrounding the aiming circle indicate that the laser is  
being transmitted. Once a range has been acquired, you can release the power button. The crosshairs

surrounding the aiming circle will disappear once the power button has been released (i.e. the laser is no  
longer being transmitted). Note: Once activated, the LCD will remain active and display the last distance  
measurement for 30 seconds. You can depress the power button again at any time to distance to a new  
target. As with any laser device, it is not recommended to directly view the emissions for long periods of  
time with magnified lenses. The maximum time the laser is transmitted (fired) is 10 seconds. To re-fire,  
press the button down again.  
OPTICAL DESIGN  
Magnification and Coatings  
The VLR II features 5x magnification and fully coated optics. A liquid crystal display (LCD) is mounted  
within the optical system and when activated, displays a reticle for targeting and a yards indicator.  
Inherent in the manufacturing process are small black spots that appear in the optical system. These are  
8
 
VLRII_1LIM.indd

7/11/08 9:00:28 AM  
a natural characteristic of the LCD and cannot be fully eliminated in the manufacturing process. They  
do not affect the distancing performance of the unit.  
LIQUID CRYSTAL DISPLAY (LCD) INDICATORS  
Your VLR II LCD incorporates illuminated indicators that advise the user unit of measure, when the laser  
is actively firing, when a target has been acquired, BullsEye™ targeting mode, and Bow mode.  
A summary of these features is presented below:  
UNIT OF MEASURE OPTIONS  
The VLR II provides distance in yards (indicated within the LCD to right of the main distance readout  
as Y).

ACTIVE LASER  
Crosshairs surrounding the aiming circle indicate that the laser is being  
transmitted. Once a range has been acquired, you can release the power  
button. The crosshairs surrounding the circle will disappear once the power  
button has been released (i.e. the laser is no longer being transmitted).  
BullsEye™ (LCD Indicator -  
)
The VLR II was especially designed with hunters in mind and will always function with BullsEye mode on.  
This advanced mode allows easy acquisition of small targets and game without inadvertently getting  
distances to background targets that have stronger signal strength. When  
more than one object has been acquired, distance of the closer object will be  
displayed and a crosshair will surround the BullsEye™ indicator informing the  
user that distance to the closer object is being displayed in the LCD.

7/11/08 9:00:28 AM  
Press the POWER button to turn the unit on. Next, align the aiming circle  
onto the object (i.e. deer) that you want distance to. Next, press and hold  
the POWER button and move the laser slowly over the deer until crosshairs  
surround the BullsEye indicator. If the laser beam recognized more than one  
object (i.e. deer and background trees), distance of the closer object (i.e.  
deer) will be displayed and crosshairs will surround the BullsEye indicator  
informing the user that distance to the closer object is being displayed in the  
LCD (Figure 1). There may be times when only the laser beam only sees one  
object in its path. In this case, the distance will be displayed, but because  
more than one object was not acquired, crosshairs will not surround the  
BullsEye indicator.

TIP: While pressing the POWER button, you can move (SCAN) the device slowly from object to object  
and intentionally force the laser to hit multiple objects to ensure that you are only displaying the closest  
of the objects recognized by the laser.  
ARC Angle Range Compensation): In addition to all of the features described above, the VLR II is an  
advanced premium laser rangefinder featuring a built-in accelerometer-based inclinometer that digitally  
displays the exact angle from -60 to +60 degrees of elevation and is +/- 1.0 degree accurate.  
The Cabela’s VLR II by Bushnell® solves a problem bow-hunters have been faced with for years. The  
problem: Bow-hunters have struggled with extreme uphill and downhill angles because of how these  
angles alter true horizontal distance to your target. The Solution: VLR II’s integrated inclinometer provides  
elevation angle to allow for distance compensation when targeting objects that are either uphill or  
downhill.

Bow Mode (  
): Displays line of sight distance, degree of elevation, and true distance range from  
5-99 yards / meters and a maximum inclination of +/- 60°.  
Once the range is displayed, continue to hold the POWER button down for approximately 2 seconds  
while holding the aiming circle on the object and keeping the unit as steady as possible so as to allow the  
inclinometer enough time to measure angle. Then release the POWER button. Once you have released  
the power button, a degree of angle and compensated range will be displayed beneath the line of sight  
distance as seen in the images below.  
BOW MODE EXAMPLE  
Line of sight is 32 yards, angle is -44 degrees, and the Angle Range Compensated distance is 23 yards.  
13  
 
VLRII_1LIM.indd 13

The “ ” means “play” or “shoot as,” so instead of shooting as 32 yards, shoot as 23 yards. If you were  
to shoot as if 32 yards, you would shoot over the top of the deer because of the severe angle.  
The line of sight distance will display in the primary numeric display and the inclination and horizontal  
distance will display in the secondary numeric displays. Bushnell determined through extensive testing and  
14  
 
VLRII_1LIM.indd 14  
7/11/08 9:00:30 AM  
interviews with high-profile bow hunting experts that multiple bow ballistic groups were not necessary.  
Bow-hunters want to know true horizontal distance because that is how they practice shooting, and once  
they confidently know that, they can make any necessary adjustments. Giving the bow-hunter anything  
else other than horizontal distance creates additional confusion and uncertainty.  
Many people mistakenly believe that uphill shots perform differently from downhill shots because of  
gravity. However, it is not due to gravity, but more of an aberration of the sighting system used on bows.  
The sighting pin on a bow resides several inches above the mechanical axis of the arrow. For example,  
when one is aiming 23 degrees up an incline, the arrow is at a different angle.  
NOTE: We simply took the most commonly used features and included them all in a simple to use, one  
button operation device. This laser rangefinder always functions in yards unit of measure, BullsEye™  
Targeting Mode, and Bow mode.

CLEANING  
Gently blow away any dust or debris on the lenses (or use a soft lens brush). To remove dirt or fingerprints,  
clean with a soft cotton cloth, rubbing in a circular motion. Use of a coarse cloth or unnecessary rubbing  
may scratch the lens surface and eventually cause permanent damage. For a more thorough cleaning,  
photographic lens tissue and photographic-type lens cleaning fluid or isopropyl alcohol may be used.  
Always apply the fluid to the cleaning cloth - never directly on the lens.  
TROUBLE SHOOTING TABLE  
If unit does not turn on - LCD does not illuminate:  
• Depress POWER button.  
• Check and if necessary, replace 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  
3 -volt lithium battery.

If target range cannot be obtained:  
• Make sure LCD 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.
