How Digital Technology Works; Ranging Accuracy - Bushnell GForce DX 1300 ARC User Manual

HOW OUR DIGITAL TECHNOLOGY WORKS
The G Force DX 1300 ARC™ emits invisible, eye safe, infrared energy pulses. The G Force DX 1300 ARC'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 G Force DX 1300 ARC™ 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 900 yards / 823 meters while for highly reflective objects the maximum is 1300 yards / 1189 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 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.
E.S.P.2™ (Extreme. Speed. Precision. 2nd generation), our advanced second generation ranging technology, provides the fastest, most
accurate ranging measurement based on target conditions. The laser analyzes multiple individual measurements to the target and calculates and
displays the best possible result. Target variations such as reflectance, shape and color can affect the accuracy of a laser measurement, but E.S.P.2™
automatically assesses the conditions and improves the measurement up to 1/2 Yard Accuracy whenever possible from 5–199 yards. When this occurs,
display readout precision will be refined to 1/10th yard.
