Overview
Your NVD-NORS210 Night Vision Scope is a modern, universal
night vision device designed for a wide range of activities
from professional to amateur activity:
• Night observation and hunting
• Patrolling and safeguarding
• Rescuing and searching works
• Night photo and video shooting.
The device is equipped with a First plus Generation high-
quality electronic-optical image intensifier (Gen. Super I+)
employing the principle of multiple intensification of the
image brightness in the visible and IR radiation which
guarantees an up to 150-350 m observation range.
NOTE.
Observation and identification range provided by the
device depends on the value of natural night light,
type of the objective lens used, transparency of the
atmosphere and contrast between the target and
background. The identification range increases in the
conditions of good lighting, at moonlight night given
outside illumination, if the target is situated on a
light background (sand, snow). The identification range
decreases in the conditions of weak lighting, low
transparency of the atmosphere, if the target is
situated on the dark background (plough-land, stems of
trees, etc.).
