The Nikon Callaway 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 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

SAFETY AND OPERATION PRECAUTIONS

• Do not look into the optics from the objective side after havng depressed the POWER button and even after measurement has been completed, as this may result is serious damage to your eyesight.
• Never look directly at the laser beam or directly at the sun when using the Nikon Callaway Laser Rangefinder.
• Do not aim at the eye while operating the Nikon Callaway Laser Rangefinder.
• Do not operate the unit with other additional optical elements, such as lenses or binoculars. Using an optical instrument together with the Callaway Laser Rangefinder increases the danger of damaging the eyes.
