Raise binoculars to your eyes and you can see everything far away as if it was right in front of you. Here, since they are, in effect, half the size of a regular pair of field glasses, better quality optics can be afforded, as the cost will be proportionally lower.
There are small as well as giant binoculars. How does one choose a binocular? Fortunately, the new weatherproof binoculars are fit for rough use.
Size is dictated by the objective lens. Cost is another factor to consider. 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.
It is also useful in ranging an object that is not perfectly horizontal or vertical, enabling you to determine the range without tilting the entire binoculars. The coating cuts down on reflected and fragmented light inside your binoculars, and so increases, the brightness and clarity of the image. Capturing as much of that as possible is good as it means all the available light is getting to where you want it.
There is nothing like owning your own telescope, and being able to direct it through the sky to uncover a sea of beauty. It's really easier to choose when you know more about them.
