This night vision device can be used as a hand-held monocular, hands-free, goggle, or weapon-mounted system. It comes with an f/1.2 objective lens, a CR123 battery and a head mount. This is a good choice for Law Enforcement professionals and private users who demand exquisite performance, friendly controls and easy system customization.

There are many different variables that affect the distance that one can see with a night vision device, among them the object's size, the level of details being sought from the object and the conditions of observation. 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 the method of calculation varies by manufacturer.

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. No matter what, bright light in any form is not good for the longevity and performance of image intensifier tubes.
