Following is a reference table listing the ranges of the RX-1300i TBR rangefinder
under different conditions:
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 .
