Following is a reference table listing the ranges of the various models under different conditions:
MAXIMUM RANGE
CONDITION | ||
Reflective Target (yd/m) | 600/550 | 750/685 |
Trees (yd/m) | 500/455 | 600/550 |
Deer (yd/m) | 400/365 | 500/455 |
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.
