If you want to know which type of binoculars are the best or most powerful, you would have to separate them into their classifications or their categories. You can not compare apples and oranges and you also can not compare one type of binocular to another.They are the only ones in the world that provide three angular degrees of recognition range providing the most stabilized binoculars available. They come with a field of view of 168 at 1,000 yards with a 20 x magnification factor. With an eye relief of 11mm and a 2.5 exit pupil, these Monocular Telescope show things in a bright clear view.

There are also another type considered to be the most powerful long range observation binoculars. The list could go on and on and on for ever. The point I am trying to make is how can you say the Most Powerful Binoculars and expect to get one single product? There are so many different types of binoculars and so many specialty binoculars that you would have to be a lot more specific. Saying the most powerful is sort of like saying the most beautiful flower.
