Binoculars come in different sizes and shapes to suit different purposes. Think about it, binoculars are inexpensive, highly portable and require no complicated setting up procedure.
Perhaps you are planning a sight-seeing trip to some exotic location. 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. A telescope also gives you the ability to learn and see something new every day.
Another feature to consider are the lens caps. So if you have a pair of binoculars with 8x magnification, they should have an objective diameter of 40. The best result is achieved when multiple layers of coatings are applied, to the front and rear of the lens.
The range of you binocular depends on three things, its gain, resolution and magnification. You may not be planning on getting them wet, but things happen; you might trip and drop them in a mud puddle, take them out on a foggy day, or you might get caught in a freak rain shower. Maritime binoculars are now being crafted with state-of-the-art compasses, and lightweight water proof casing.
Hunter's binoculars are now being designed with range finders and birdwatchers are seeing more of the increasing stabilization features they need in the latest birdwatching binoculars. Also be aware, that night binoculars cost much more than ordinary binoculars.
