This booklet will help you achieve optimum performance by explaining its adjustments and features as well as how to care for this device. To ensure optimal performance and longevity, please read these instructions before using you're Sport® 850 laser rangefinder. HOW OUR DIGITAL TECHNOLOGY WORKS The Sport® 850 emits invisible, eye safe, infrared energy pulses. The Sport® 850's Advanced Digital microprocessor and ASIC chip (Application-Specific Integrated Circuit) results in instantaneous and accurate readings every time. 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. RANGING ACCURACY The ranging accuracy of the Sport® 850 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 600 yards / 549 meters while for highly reflective objects the maximum is 850 yards / 777 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. White 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 2
