Battery life

Approx. 9,400 times (at approx. 20°C (68°F))
This figure may differ according to conditions such as temperature and other factors. Use only as a guide.

• The battery supplied with this Nikon Laser Rangefinder is for operation checking. Due to natural electrical discharge, the life of this battery will likely be shorter than that noted above.

About laser

This product 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.

Measurement may be inaccurate or fail in the following cases:

• In snow, rain or fog
• Small or slender target
• Black or dark target
• Target has stepped surface
• Moving or vibrating target
• When measuring the surface of water
• Target measured through glass
• When the target is glass or a mirror
• When laser incidence to the target's reflective surface is oblique
