The 10-30x50mm Gladiator Zoom Binocular from Barska is designed for long distance terrestrial and astronomical viewing. The variable magnification range of the binocular allows the viewer to scan a large field of view and then zoom in on the selected object for a closer and greater detailed look. A zoom thumb-lever for making quick and smooth magnification changes is featured. Fold-down eyecups are incorporated into the eyepieces for comfort viewing with or without eyeglasses.
The 10-30x50mm Gladiator Zoom binocular has BAK7 porro prisms and tinted ruby colored lenses to help lessen ultra-violet glare. Zoom magnification, multicoated optics, large objective, shock-absorbing rubber armor, and tripod-adaptable fittings for a steady view, contribute to a binocular that's ideal for all outdoor activities and sporting events.

Comments about BARSKA 10-30x50mm Gladiator Zoom Binocular:
The focus is a little bit hard to get because the mechanism is not so precise. When you get, the image is very good even in low light situations. Regarding the zoom option, it's useless. It's impossible to obtain focus with it. And mechanism gets even worse to use - hard and not precise.
Well, in normal use, without zoom (this means 10x) it's ok, otherwise, not so good. But it's cheap at least.
