The Nikon Laser IRT emits invisible, eyesafe, infrared energy pulses that reflect off
the selected target back to its optical receiver. Sophisticated precision charge
circuitry is used to instantaneously calculate distances, by measuring the time it
takes for each pulse to travel from the rangefinder to the target and back. The
maximum range of the instrument depends on the reflectivity of the target, its color,
surface finish, size and shape.
The following factors ensure best range and accuracy:
• Nighttime use
• Cloudy weather
• Bright-colored targets
• Targets with highly reflective surfaces
• Targets with shiny exteriors
• Large-size targets
• Shooting targets facing at 90 degrees
Measurement may result in inaccuracy or failure in the following cases:
• Slender or small target
• Target has diffusing reflective surface
• Target does not reflect the laser beam (glass, a mirror, etc.)
• Black target
• Target has pronounced depth
• In snow, rain or fog
• Target measured through glass
• Reflective surface measured from diagonal direction
• Moving target
• Obstacle moving in front of the target
• When targeting the surface of water
