Your Bushnell ELITE 1500 w/ARC is an advanced premium laser rangefinder comprised of Digital Technology allowing range readings from 5-1500 yards / 5-1372 meters. Measuring 1.7 x 5.1 x 3.7 inches, the 10-ounce ELITE® 1500 delivers superb and accurate range performance to +/- one yard. Featuring Angle Range Compensation (ARC) that Accounts for steep terrain. The ELITE® 1500 features Selective Targeting Modes, Superb Optical Quality, 100% Waterproof Construction, and Bushnell's RainGuard® coating.The ELITE® 1500 emits invisible, eye safe, infrared energy pulses. The ELITE® 1500'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.The ranging accuracy of the ELITE® 1500 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 1000 yards / 914 meters while for highly reflective objects the maximum is 1500 yards / 1373 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
