Bushnell Yardage Pro 20-0750 User manual

Y A R D A G E P R O ® Your YARDAGE PRO
®
750 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 fine instrument. To
ensure optimal performance and longevity, please read these instructions before using your
YARDAGE PRO
®
750.
I N T R O D U C T I O N The YARDAGE PRO
®
750 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 YARDAGE PRO
®
750 is plus or minus
one yard / meter under most circumstances (see description of “Precision”
indicator below). The maximum range of the instrument depends on the
reflectivity of the target. The maximum distance for most objects is
750 yards / meters while for highly reflective objects the maximum is
999 yards / 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 effect 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.
O P E R A T I O N A L S U M M A R Y While looking through the
monocular, depress the fire button (see Figure 1) (top right hand side of unit)
once to activate the inview display system (LCD). Aim the YARDAGE PRO
®
750
at a target at least 21 yards away, depress and hold the fire button down
until range reading is displayed. Release the fire button. Note: Once
activated, the YARDAGE PRO
®
750’s LCD will remain active and display the last
distance measurement for 30 seconds. You can depress the fire 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.
F E A T U R E S The YARDAGE PRO’s sophisticated circuitry allows you to
select between various units of measure and targeting modes. In addition, your
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 (see Figure 2). A summary of these features is presented below:
U n i t o f M e a s u r e O p t i o n s The YARDAGE PRO
®
750 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 (see Figure 3) (lower right hand side of the unit) 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
YARDAGE PRO
®
750 will return to the last setting used, each time the unit is turned-on.
T a r g e t i n g M o d e s
STANDARD (LCD Indicator - none) – This setting allows most targets to be distanced up to
750 yards. Used for moderately reflective targets that are typical of most distancing situations.
SCAN (LCD Indicator - “SCAN”) – This mode allows the range to be continuously 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 at a closer distance. The minimum distance in this mode is the
same as in the standard mode.
Illuminating Indicators
AC T I VE LASER (LCD Indicator - “LASER”) – Located in the upper left portion of LCD. When
illuminated, indicates that energy pulses are being emitted from unit.
T A R G E T Q U A L I TY G A U G E (LCD Indicator - “TARGET QUALITY”) – Located in the upper
middle portion of 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).
P R E C I S I O N P A R A M E T E R I N D I C A T OR (LCD Indicator - “PRECISION”) –
When 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.
L O W B A T T E R Y C H A R G E (LCD Indicator - “BATT”) – When illuminated,
indicates the battery charge is low and battery should be replaced.
R o l l D o w n E y e c u p The YARDAGE PRO’s monocular is equipped
with a rubber eyecup designed for your comfort and to exclude extraneous
external light. If you wear sun / eyeglasses, roll down the eyecup. This will
bring your eye closer to the ocular lens, thus providing improved field of view.
S P E C I F I C A T I O N S :
O p t i c a l D e s i g n The YARDAGE PRO
®
750 features a Perma Focus
®
monocular optical 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 battery indicators. Inherent in the manufacturing process are
small black spots that appear in the optical system. These are a natural
characteristic of the LCD, cannot be fully eliminated in the manufacturing process
and do not affect the distancing performance of the unit.

750 is powered by one 9-volt
alkaline battery. (Use only high quality alkaline batteries. Do not use heavy duty or
lithium batteries).
C L E A N I N G 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
Unit does not turn on - LCD does not illuminate or L CD contrast has decreased:
• Depress fire button (top right hand side of unit).
• Check and if necessary, replace battery.
There is no reset button to clear last range reading before ranging another target:
• The last range reading does not need to be cleared before ranging another target. Simply aim at the new target using the
LCD’s reticle, depress the fire button and hold until new range reading is displayed.
There are black spots in the optical system:
• These are a natural characteristic of the LCD and can not be fully eliminated in the manufacturing process.
Target range cannot be obtained:
• Make sure LCD is illuminated.
• Make sure that the fire button is being depressed (as opposed to mode button).
• 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 fire button.
• A less reflective target will require you to scan its surface to find the most reflective point in order to obtain a distance. To
do this, hold the fire button and scan LCD reticle across the target’s surface to try and register a “hit” on the target quality
meter. When the target quality gauge registers a hit (indicated when the first square illuminates), stabilize the unit in place
and hold the fire button until a range reading is displayed.
