Bushnell Sport 450 Instruction manual

Lit. #: 91-0179/03-01
Your YARDAGE PRO SPORT’s LCD incorporates illuminated indicators that advise you unit of
measure, when the laser is active, the battery charge is low, and when a target has been
acquired. A summary of these features is presented below:
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, remove the battery cover slide.
Locate the internal yards to meter slide switch. To measure in yards, slide the switch to the
"Y" position. To measure in meters, slide the switch to the "M" position.
) When the low battery symbol
is displayed in the upper right-hand portion of the LCD, the battery charge is getting low and
the 9-volt alkaline battery should be replaced.
Target Acquired: Informs the user that a distance measurement has been obtained. The
message "TARGET ACQUIRED" will appear in the top portion of the LCD. The distance
measured will appear at the bottom of the LCD in numerical form.

Your YARDAGE PRO SPORT 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
Power Button
Your Bushnell YARDAGE PRO SPORT is the world’s most simple to use, yet
advanced laser rangefinder. Using Digital Technology and measuring a mere
3.9 x 3.1 x 1.7 inches, the 7.4 ounce YARDAGE PRO SPORT delivers superb and
accurate range performance to +/- one yard. Range to a deer or a golf flag as
far as 200 yards out, or to a tree 450 yards away for a reference point. The
single button operation allows outdoor enthusiasts to easily measure
distance with confidence.
The YARDAGE PRO SPORT emits invisible, eyesafe, 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.
The ranging accuracy of the YARDAGE PRO SPORT 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 450 yards / 411 meters while for highly reflective objects the
maximum 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. 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.
OPTICAL DESIGN The YARDAGE PRO SPORT 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, yards / meters, 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 and cannot be fully eliminated
in the manufacturing process. They do not affect the distancing performance of the unit.

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.
While looking through the monocular, depress the power
button once to activate the inview display system (LCD).
Aim the YARDAGE PRO SPORT at a target at least 10 yards
away, depress and hold the power button down until range
reading is displayed. Release the power button. Note: Once
activated, the YARDAGE PRO SPORT’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.

Before returning for repair, consult the Trouble Shooting Table below.
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
alkaline battery. Heavy Duty alkaline batteries are NOT recommended.
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 power button and hold
until new range reading is displayed.
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.
