Your CABELA’S VLR by BUSHNELL® is a precision 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 precise laser rangefinding instrument. To ensure optimal performance and
longevity, please read these instructions before using your Cabela’s VLR.

INTRODUCTION

Your CABELA’S VLR is a very compact advanced laser rangefinder. Using Digital Technology and
measuring a mere 1.5x4x2.75 inches and weighing 6.8 ounces, the CABELA’S VLR delivers superb and
accurate range performance to +/- one yard. Range to a deer as far as 300 yards out or to a tree at 570
yards away for a reference point. The unique shape and palm size allows outdoor enthusiasts to easily
grip the rangefinder with a single hand and drop it into a pocket when not in use.

The rugged and weather resistant CABELA’S VLR features popular “Scan” and “>150” modes and includes
a carrying case. Scan mode provides continuous distance measurements as multiple targets in the field of
view are scanned. The “>150” mode only captures distance measurements of objects greater than 150
yards away, enabling distance measurement through foreground clutter like brush and branches.

The CABELA’S VLR emits invisible, eye-safe, infrared energy pulses. Sophisticated digital technology and
a high-speed clock are used to instantaneously calculate distances, by measuring the time it takes for each
pulse to travel from the rangefinder, to the target, and back.

The ranging accuracy of the CABELA’S VLR 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 570 yards / 521 meters while for highly reflective objects the maximum is 700
yards / 640 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 object is
being distanced to.

The color, surface finish, size and shape of the target all affect reflectivity and range. The brighter the
color, the longer the range. Red 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.

OPERATIONAL SUMMARY

While looking through the monocular, depress the power button once to activate the in-view display
system (LCD). Aim the CABELA’S VLR at a target at least 10 yards away, depress and hold the power
button down until range reading is displayed. Release the power button. Your CABELA’S VLR features an
adjustable eyepiece. Simply rotate the monocular until the reticle and object distanced to are in focus to
your eye. Note: Once activated, the LCD will remain active and display the last distance measurement for
6 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.
