The monocular is the most popular among the night vision. This device has low weight, as well as compact size. The device lies comfortably in your hand, in case you need to focus on a target for accurate observation. However, almost all night vision monoculars are equipped with a monocular attachment, right before the eye of the beholder, thus freeing up hands for other manipulations.
Another advantage over dimensional devices is the ability to attach a monocular night vision to a helmet or rifle using special fasteners. Due to its parameters, it will not obstruct human movement and will increase opportunities for vision in the dark many times.
There are two types of devices - digital and electronic-optical. Some models are equipped with multiple lenses to match the required magnification.
