Night Vision Binocular

Definition of a "pocket binocular"

You get big binoculars and then you get compact binoculars. Among the latter you get even smaller ones, known as "pocket binoculars".

A compact binocular is a pocket binocular when:

1.the compact is so small, it can actually fit into a jacket or even a shirt pocket, depending on how big the pocket is, which is about 153 millimeters (6 inches) in length, 101 millimeters (4 inches) in width and 77 millimeters (3 inches) in height;

2.Weight: It should be about 16 ounces if you wish to include reverse porro designs, but if not, not more than 12 ounces for roof prism pocket binoculars.

3.The best type of binocular design is the type where the objective lenses and eyepieces are in the same line, known as the roof prism binoculars. They are smaller and more light-weight than the porro binoculars. When you're not using it, it can fold even smaller.

Why should you consider a pocket binocular?

1.The smallness of all pocket binoculars - in particular a roof prism design - makes them very convenient.

2.A pocket binocular is light enough that the weight will not be a factor at all - whether you're attending a game at the super bowl or on a trip in the great outdoors or.

3.When you want to focus on something really close to you, nothing beats a pocket binocular. They are simply better than their bigger brothers.

4.A pocket can deliver a high quality image to the eyes of the beholder. It's small size does not necessarily impair its quality of viewing.

The negative points of pocket binoculars

1.How bright the image is which the beholder sees, is determined by the diameter of the objective lenses (apertures). Since pocket binoculars have smaller apertures than bigger binoculars, less light enters the instrument through the apertures. Luckily this will not be an issue when the sun is shining brightly - only when overcast conditions or when the light is not that clear (early morning, late afternoon).

2.The optics of the eyepieces, diameter of the apertures and power of a binocular determine the width of the scene you're seeing through your binocular, known as the field of view (FOV). Since pocket binoculars have smaller apertures, you could end up with a smaller FOV you would like. Check the specs before you buy.

Choices you have to make when considering buying a pocket binocular

1.Use: Why do you want a pocket binocular? Will this be the only pair of binoculars you have, or just an extra, convenient one? These considerations are important not only in terms of how much you're willing to pay, but also what model will suit you best.

2.How much are you willing to pay for your pocket binocular? In the case of binoculars quality does come at a price and for a good instrument you will have to be willing to pay more. All in all, the purpose you have in mind for the instrument will also play a role. If it will be the only binocular you'll have, consider paying more.

3.Quality: Requirements of quality remain the same - whether you're looking for pocket, compact or full-size binoculars. Lenses and coatings: Make sure that the lenses are made from Bak-4 glass and are "fully multi-coated". Excellent optics will have to make up for the fact that the smaller apertures will let in less light than in the case of ordinary size binoculars. Weatherproof: A weatherproof instrument is always a good idea, in particular if you intend using it on trips in the great outdoors.

4.The reverse porro pocket binoculars are slightly heavier than the roof prism pocket binoculars. Is this a problem to you? And what about size? Make sure it's not too small! Your hands and pocket size might differ from the average!
