    12 to 36 power. So it will magnify up to 36 power. Hunting, seeing things at a distance, and birdwatching would be some uses. As for distance, they will enable you to see billions of miles or kilometers. Look at a star cluster for instance.

    I actually wouldn’t touch that with a ten foot pole. First of all it’s a zoom binocular, zoom optics are very complex to make, that means expensive. Not until very recently do good camera lenses comes in zoom, and those aren’t cheap. So such a high power lens at only $60, you’ll be looking at poor glass and poorly designed eye piece.

    Powerful binos in the 20-30 power range is used for astronomy, and marine uses, attached to a sturdy tripod. However it’ll be rather useless for bird watching. The high power makes for a very narrow field of view, makes it hard to actually find the bird.
