• Water condensation or mold may
occur on the lens surface because of
high humidity. Therefore, store the

dry place.
After use on a rainy day or at night,
thoroughly dry it at room
temperature, then store in a cool,

The Nikon Laser Rangefinder uses an invisible
laser beam for measuring. It measures the time the
laser beam takes to travel from the rangefinder
to the target and back. Laser reflectivity and
measurement results may vary according to climatic
and environmental conditions, as well as the color,
surface finish, size, shape and other characteristics
of the target.
The following conditions makes measuring easier:
• Cloudy weather
• Bright-colored target
• Target with highly reflective surface
• Large-size target
• When laser incident angle to the target is close to 90
degrees
Measurement may result in inaccuracy or failure in
the following cases:
• Target has small or slender reflective surface
• Target has diffusing reflective surface
• Target does not reflect the laser beam to the
rangefinder
• Target has totally reflective surface (glass, mirror,
etc.)
• Black target
• Target has stepped surface
• In snow, rain or fog
• Target measured through glass
• Reflective surface measured from diagonal direction
• Moving or vibrating target
• Obstacle cutting across in front of the target
• When measuring the surface of water
