Bushnell Yardage Pro 20-1925 User Manual page 5

INTRODUCTION
Your Bushnell Yardage Pro X500 is the world's most simple to use, yet advanced laser rangefinder. Using Digital
Technology and measuring a mere 4.2 x 3.6 x 1.9 inches, the 7.4 ounce Yardage Pro X500 delivers superb and accurate
range performance to +/- one yard. Range to 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 X500 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 X500 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 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. 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.
