The Nikon Laser Rangefinder 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. Laser reflectivity and measurement results

may vary according to climatic and environmental

conditions, the colour, surface finish, size, shape and

other characteristics of the target.

The following factors ensure better range and

accuracy:

• Night time use

• Cloudy weather

• Bright-coloured 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 to the

rangefinder (glass, a mirror, etc.)

• Black target

• Target has varying depths

• 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
