Leupold 172707 overview

  • 1Description

Bridging a comfortable middle ground between compact and full-sized, the Leupold 10x30 BX-1 Yosemite Binocular, in gray, is designed with smaller objectives and narrower interpupillary adjustment range so they can be comfortably used by children as well as most adults. To help offset the lower light-gathering ability of the smaller objectives, the Porro prisms are phase-corrected and the entire optical path is fully multi-coated; which improves light transmission, color rendition, clarity, and contrast across the wide field of view.

Built for the trail, the Yosemite's optical tubes are nitrogen-filled and O-ring sealed to be waterproof and prevent internal fogging when moving through extreme temperature changes. The entire chassis is wrapped in a gray protective rubber armoring that provides a slip-resistant grip in cold or wet conditions. These binoculars are offered here with a case and shoulder strap.

    Leupold 172707 reviews

    10x30 BX-1 Yosemite Binocular (Shadow Gray) is rated 4.8 out of 5 by 5.
    Rated 5 out of 5 by from Great buy I have a pair of 8x30 Leupold yosemites and I wanted to get some 10x binoculars. I read all the great reviews about the 10x42 Redfield Rebel binoculars and ordered a pair. I was disappointed in both the brightness and clarity of the Redfields. I have some blue spruce trees that at 100 yds. I could easily make out individual needles with the Leupold Yosemite's. The Redfield's image was not nearly as clear and had less depth. I went to a local store and compared a pair of 10x30 Yosemite's with some 10x42 Redfield Rebels. In the store I couldn't note too much difference in brightness but the Leupold's image had a lot better resolution (clarity) and depth. The Leupold's are porro prisms while the Redfields are roof prisms. Most sources say that porro prism binoculars can be made a lot cheaper for the some quality of image. Many of the reviews on the Redfields said they had as good of image as binoculars costing $400 or more. I checked out several $300 to $400 pairs of binoculars and the rebels compared quite well. But I found the Leupold Yosemite's to be much superior. The Yosemite's are quite small and easily used by young children as well as adults. They also only weigh 17 oz. about 1/2 pound less than the Redfields. I returned the Rebels and will be getting another pair of the Leupolds. This time I'm ordering the 10x30 Yosemite's. They are a tremendous value.

    Rated 5 out of 5 by from My Wife scarfed them I bought the 10X30 Leupolds for two reasons: One, they are light weight, and Two, wide angle views. I got to use them one night (tried them on the stars) and my wife scarfed them next day. We go birding often and they were just what she wanted. She was using a pair of 8X40 Bell and Howells. The Leupolds are much lighter and according to her much more powerful. She is one very happy camper with them.
