Mostly because I live right at the foot of mountain ranges and one side of my valley is open grasslands as I'm close to the Great Basin desert and so I hike up the tree filled other side of the valley and just scope the other side which could be three or more miles away. On my upper deck I have a pair of 25x100 Oberwerks and often see the elk and coyotes, Golden Eagles and Red Tails, fairly close up or some hikers passing a joint on top of Grizzly Peak. That's fun as it's about three miles away or more as I said. I'm a spy on a mission doing surveillance so watch out lol. I often look down into town and watch all the humans like a giant colorful ant hill of action. I love a wide FOV as I deal with winter blues and If it's a sunny day I love just to see bushes and brown grass in the sunlight. I think that's my favorite sight in a bino. You don't really need top notch optics for that.
You are a lucky guy Crow - many would much rather be in a great location with a not so good binocular than vice versa. Here in the UK not all that many birders will have seen a wild golden eagle - I never have. You'll have to go a long way north to places like the Scottish Highlands, and often cover a lot of ground, just to see one in Britain. Being able to see birds like that on a regular basis would be a real privilege, and your area looks like it would let you follow them for miles, too, with that 25x100 setup. As Proverbs 30:18/19 goes:
There be three things which are too wonderful for me, yea, four which I know not: The way of an eagle in the air; the way of a serpent upon a rock; the way of a ship in the midst of the sea; and the way of a man with a maid.
Regarding your original post, I haven't personally used the 10x30 class binoculars (only looked through a Canon 10x30IS briefly) and wouldn't be able to recommend one that is good value for $200, or $500 for that matter. But when others here express that making a binocular of that magnification x objective configuration is more difficult (and therefore costly) than say an 8x40, I can relate to that, because the same is true with photographic lenses. A quality 50mm f1.8, for instance, can cost a fraction of some other focal lengths because of its simpler optical design. But then, it's very true that not everyone wants, needs, or can perceive alpha-level optical quality. Some situations are more demanding than others: enjoying the view over a city or a mountainside, for instance, compared to trying to tell whether a bird something like 1.5 km away is a black-headed gull or a peregrine. I have tried a fair number of binoculars for that latter job, from classics to alphas, and sadly (as I dearly wish I could distinguish no differences between them) to my eyes, the older glass is definitely outperformed at long distance, and/or against grey cloud and when visibility is a little on the marginal side.
Over the last two or three months I have become uncomfortably aware that my eyes' accommodation is not what it used to be, and am looking forward (forgive the pun) to the further age-related deterioration of my eyesight with dread. I am keeping a couple of the old classics for that day, as they feel nicer in the hands than anything else, and I guess that won't change even if my eyesight has gone to pot.
