« 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 2 YP Sport 450 1LIM.indd 412/17/04 11:01:35 AM3 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 YARDAGE PRO SPORT at a target at least 5 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. FEATURES 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: UNIT OF MEASURE OPTIONS – The YARDAGE PRO SPORT 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, YP Sport 450 1LIM.indd 512/17/04 11:01:36 AMremove 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.
