Leupold RX-1400i TBR/W Complete Operating Instructions page 12

Following is a reference table listing the ranges of the RX-1400i
TBR/W under different conditions:
CONDITION
Reflective Target
Trees
Deer
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 . Tan game coats are
more reflective (and thus provide a more solid reading) than a
black roof . 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 .
The sun generates infrared energy that can degrade ranging
performance in bright conditions or when ranging towards
the sun .
