What is a Nigh Vision Device
A night vision device (NVD), also known as NOD – is a night observation device, an optoelectronic device that enables you to see the objects in absolute darkness. The image produced is a monochrome, generally with shades of green or gray. It can be used for wildlife observation, hunting, law enforcement and even for military aims.
Those who use night vision devices for hunting should also get a red dot sight which will help you hit the target.
What Features to Compare
Firstly, you have to decide where and how you are going to use it. What model suits you the best - binocular or monocular? Do you prefer a headgear or a wrist strap? Bigger or smaller lens diameter? In order to make the right choice, discover more about Design and Construction.
Detection is the second criterion you should pay attention to. We mean such important features as a visual field or a focus range. Besides, there are some other characteristics that present productivity.
Lens Protection is a really significant feature. It is one of the main features of the night vision scopes. As a rule, manufacturers take care of kicks, drops or frost protection.
Battery life plays the great role when you take NVD outside. You never know how much time your observation will take and if there is a chance for charging.
Portability is also very important. It is preferable to have a light Night Vision Device. Your observation may require more time and fewer moves. In some cases, small size and compact design can help you to hide it in a pocket or purse.
