At first glance, a 10x
binocular, instead of a 7x or 8x
binocular would seem to be the best choice for a hiking or
hunting binocular in the mountains. After all, distances can be enourmous in the mountains with great valleys, ridges, canyons and so on greeting us as we hike. Is a 10x binocular, though, really an automatic choice for
mountain work? Put yourself in my place. I have backpacked and camped above 10,000 feet more than once. I am in good shape, but I am a flatlander (not by choice). The air is thin at high elevations and, unless you are acclimated to higher altitudes, any activity will have your heart pounding like a hammer. For sure, getting aclimated does not happen, overnight and if you are out of shape, you probably didn't take a long enough vacation. Then, too, you might already have your hands full with a heavy pack and/or other gear. So, do you really want to fight with a 10x
binocular to hold it steady? A 10x binocular can be a challenge to steady even on the flats for many people. That's why my favorite mountain binoculars have always been a 7x or 8x. Besides, when you really need more magnification than a 7x or 8x, you need a spotting scope, not a 10x binocular.
