RANGING ACCURACY
The ranging accuracy of the HYBRID 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 1000 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. Brightly colored
targets can be ranged at greater distances. 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. In reduced light (e.g. overcast skies) the unit’s maximum range will increase.
Conversely, very sunny days will decrease the unit’s maximum range.
MAGNIFICATION AND COATINGS
The HYBRID’s laser rangefinder features 5x magnification and multi-coated optics. A liquid crystal display
(LCD) is mounted within the optical system and when activated, displays a reticle for targeting, and
indicators for distance units (Yards/Meters) and PinSeeker operation. Inherent in the manufacturing
process are small black spots that appear in the optical system. These are a natural characteristic of
the LCD and cannot be fully eliminated in the manufacturing process. They do not affect the distancing
performance of the unit.
