Re: compact binoculars?
Many years ago, I got tired of carrying a heavy binocular on a neck strap all day, and decided to get a small roof prism. Went to different stores, bought Bushnell, Simmons, Tasco and other cheapos. Did not like any of them, mostly because in bumping around they all lost focus. Returned every one for a refund. I finally bit the bullet and bought a high end Leica roof prism 10x25 binocular. That was 20 years ago, it cost $300, and now they are near $500. I still carry that binocular every time I hunt anything, and have never had a problem with it. The glass is outstanding. It is always in focus. In optics, you get just what you pay for.
