Bushnell Yardage Pro 20-0602 Instruction Manual

Your BUSHNELL YARDAGE PRO 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 BUSHNELL
YARDAGE PRO.
INTRODUCTION
The BUSHNELL YARDAGE PRO emits invisible, eyesafe, infrared energy pulses.
Sophisticated circuitry 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 BUSHNELL YARDAGE PRO 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 700 yards / 640 meters while for highly reflective objects the maximum is 999
yards / 913 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 inview display system (LCD).
Aim the BUSHNELL YARDAGE PRO at a target at least 20
yards away, depress and hold the power button down
until range reading is displayed. Release the power
button. Note: Once activated, the BUSHNELL
YARDAGE PRO's 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.
FEATURES
The BUSHNELL YARDAGE PRO's sophisticated circuitry allows you to select
between various units of measure and targeting modes. In addition, your
BUSHNELL YARDAGE PRO's LCD incorporates illuminated indicators that advise
you when the laser is active, what the quality level (a measure of reflectivity) of
the target is, what the precision tolerances of a specific measurement are and
when the battery charge is low. A summary of these features is presented below:

INSTRUCTION MANUAL
UNIT OF MEASURE OPTIONS
The BUSHNELL YARDAGE PRO can be used to measure distances in yards or
meters. The unit of measure indicators are located in the lower right portion of the
LCD. To select between yards and meters, look through the monocular, depress
the "mode" button and hold it down for approximately 5 seconds. If you are
changing from yards to meters, a change in unit of measure will be indicated by
the illumination of the METER indicator while the YARD indicator is turned off. If
you are changing from meters to yards, the opposite will occur. Note: The
BUSHNELL YARDAGE PRO will return to the last setting used, each time the unit
is turned on.

TARGETING MODES
Standard (LCD Indicator - none)
up to 700 yards. Used for moderately reflective targets that are typical of most
distancing situations. The minimum distance in the standard mode is 20 yards.
SCAN (LCD Indicator - "SCAN")
updated for 10 seconds when the fire button remains depressed. It can be used
to scan an area containing several objects or a single object that is moving.
NOTE: Objects further away require a slower scanning pace than objects a
closer distance. The minimum distance in this mode is the same as in the
standard mode.
To select between these modes, while looking through the monocular, depress
and release the mode button. Each successive depression of the mode button
will activate a different mode designation in the following order: 1) Standard (no
indicator), 2) Scan ("SCAN"), NOTE: The BUSHNELL YARDAGE PRO will return
to the last setting used, each time the unit is turned-on.
ILLUMINATING INDICATORS
ACTIVE LASER (LCD Indicator – "LASER")
LCD. When illuminated, indicates that energy pulses are being emitted from unit.
TARGET QUALITY GAUGE (LCD Indicator – "TARGET QUALITY")
upper middle portion of the LCD. Gauge indicating amount of energy pulses being
received back from the target. Gauge is calibrated to fill squares from left to right.
The higher the number of returning energy pulses, the greater the number of
squares that will fill with illumination. This gauge can be used to scan across a
target that is difficult to acquire to find the most reflective point for ranging (see
Trouble Shooting Table).
PRECISION PARAMETER INDICATOR (LCD Indicator – "PRECISION")
illuminated, indicates the distance measurement is within plus or minus 1 yard or
meter. If it is not illuminated after obtaining a measurement, the distance
measurement is within plus or minus 3 yards or meters.
LOW BATTERY CHARGE (LCD Indicator – "BATT")
When illuminated, indicates the battery charge is
low and battery should be replaced with a 9-volt
alkaline battery.

OPTICAL DESIGN
The BUSHNELL YARDAGE PRO features a Perma Focus
system for viewing your target. A liquid crystal display (LCD) is mounted within
the optical system and when activated, displays a reticle for targeting, yard /
meter and mode designations, a target quality gauge, as well as precision and low
