The Leupold GX series of rangefinders emit a series of invisible, infrared energy
pulses that are reflected off the selected target back to the optical unit. State-
of-the-art circuitry and precision computing circuits are used to calculate the
distance instantaneously by measuring the time it takes for each pulse to travel
from the GX rangefinder to the object and back.
Surface texture, color, size, and shape of the target all affect reflectivity, which
in turn affects the maximum range of the instrument. As a rule of thumb,
brightly colored targets are much more reflective than darker targets, with
black being the least reflective color. A shiny surface is more reflective than
a dull surface. Smaller targets are more difficult to range than larger targets.
Light conditions, haze, fog, rain, and other environmental conditions can all
affect ranging performance. Any factor which degrades air clarity will reduce
the maximum effective range. Bright lighting conditions (sunny) reduce the
effectiveness, producing shorter maximum ranges than those possible on
darker (overcast) days. The steadier the GX unit is held, the greater the
maximum distance.
