•  20-second continuous measuring function

The Nikon Callaway id TECH 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 best range and accuracy:

•  Nighttime 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 (glass, a mirror, etc.)

•  Black target

•  Target has varing 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
