This monocular has a magnification of 2.5x with bright 42mm objective lenses to gather lots of light.
PLEASE NOTE: There are many variables which influence the distance one sees with night vision devices-amongst them the object's size, the level of detail being sought and the observation conditions. Night vision devices detect much further under a full moon and clear skies than they will under a new moon and cloudy skies. Many different formulas are used to determine the statistic of maximum viewing range and this varies by manufacturer, so ultimately the generation of the intensifier tube is much more relevant than any quoted statistic when determining the maximum viewing range.
All night vision devices sold by B&H have mechanisms in place to protect the intensifier tube from a sudden burst of bright light, but this does not mean that bright light doesn't damage the device. Bright light in any form is not good for the longevity and performance of image intensifier tubes.
