Hopefully this isn't too far off topic.
A few years ago, I inherited my grandaddy's binoculars, which are a pair of Bino-Luxe 10x50 with a compass mounted in the top of the leather case. Grandaddy really liked nature and bird-watching. He got them sometime in the late 50s or early 60s. They're not mint by any stretch, but they've been cared for. Sometimes when the local astronomy club has a star party, I'll take them with me since they are good for looking at the moon and viewing Jupiter and Saturn. They show up small, but you know what you're viewing.
These binocs aren't considered all that collectible or valuable, but I still don't want them getting damaged. I've been thinking about getting something like them that I can carry in the car without worrying about ruining my grandaddy's binoculars. I found a similar set on the 'bay at a reasonable price. They're newer than what I have, have porro prisms like the ones I have, and are also rated at 10x50.
My question is that the measurement on the newer set says that they are 360ft at 1000 yds, where the older pair I have is more like 281ft at 1000 yds. What's the difference? Since their lenses are the same size and magnification is supposed to be the same, shouldn't that spec be the same too?
Once upon a time, I would have considered getting something from the FSU or modern-day Russia, but I'm hearing that their optics aren't as good as they once were, and most older FSU stuff has become more attractive to collectors instead of users like me.
