Laser rangefinders work by emitting a brief pulse of light
aimed at a target object. Distance is determined by the
amount of time taken for the light to emit and return to the
laser’s internal receiver. A laser’s ability to read range can
be affected by many things—mostly relating to the target
objects. Under ideal conditions, the Ranger can be expected
to range a large reflective object out to 1500 yards and deer-
sized game out to 750 yards.
Laser Performance Tips
• Light colors will usually reflect the laser pulse better than
dark ones. An exception would be snow, which can be
difficult to range.
• Shiny, reflective surfaces will usually reflect the laser
pulse better than dull, textured surfaces. Animal hair will
not reflect as well as a hard surface.
• Ranging while under cloud cover can improve laser
performance compared to ranging while under bright
sunny conditions.
• Solid objects, such as rock piles, will reflect the laser
pulse better than less dense items such as bushes.
• Flat surfaces perpendicular to the laser pulse will reflect
better than curved surfaces or surfaces angled in relation
to laser pulse.
• Ranging over water can sometimes cause false reflections
and readings.
• At longer distances, larger objects will be easier to range
than small objects.
• If you are having difficulty ranging an animal or object,
try ranging a different nearby object or use the Scan
feature to pan back and forth while watching for changes
in range number.
