Most night-vision binoculars are used by security personnel. Using binoculars is not a risk free activity.
You may use your binoculars for sporting (watching your favorite team from the stands), hunting (they won't weigh you down or take much space), birdwatching (you can hold them steady for long periods without tiring), or just everyday nature lovers. Binoculars have two specifications marked on the body of the binocular in the form of 7x 50, where the first number represents the magnification, in this case 7 times, and the second the aperture ,50mm in this case. More than a few people have been surprised to learn that binoculars go out of whack when bashed.
You will need a magnification factor of at least 7, maybe up to 10 if you have a steady hand. A telescope allows the universe to come to you, in other words objects of long distance come closer, while a microscope puts small objects to become bigger so you can see. Distance measuring is important, but binoculars with a wide field of view allow you to see a larger picture, and keep an eye on several objects at once.
But still, a good pair of night-vision binoculars will cost at least a thousand dollars. Many things, such as overall design and quality of glass impact this specification, magnification and objective lens diameter are the chief components. A tripod may be a good thing to have if you re using binoculars with high magnification.
The greater the magnification, the narrower the field-of-view. When looking for a pair of binoculars to buy you may have to shop around.
