Bino's, like any good tool- You get what you pay for- is right onthe money.
I have some Nikon 10x42's I use for deer hunting. They work fine for that, and I like em just fine for what I use them for. I have used them glassing out west, and they really don't cut it. They're better than nothing, and what I could afford at the time.
I've since bought a pair of used Kahles 10x42's, which were made by Swaro. Good glasses, and I'll see how I like em out west this year.
All that said,my #1 priority purchase next year will be a pair of Swaro's.There are none better.
I'll let my son use the Nikons, then he can carry the tylenol for the headache that comes from staring through a pair "affordable" glasses for a few hours.
