Several people have stated "put your glass on a tripod" and I agree. But.....since that answer was already given, I am going to say, carefully choose a bino that you can actually use in the scenarios you will use them. My 15x Meoptas are awesome!! But only on a tripod. If I had to handhold them, I would never use them. Way too much shakiness noticed.
I learned the hard way, over years and several pairs of good glass trying, that I CANNOT use a 10x or higher glass free handed. I was good with 8x and 9x was mostly good. The 8.5x Swaros I own now, are good if I am handholding, and absolutely terrific on a tripod etc. Just because people say that 10x42 is the way to go, doesn't mean that 10x42 is the way to go for everyone. I tried, multiple times, and I failed. But I can use a good 8x and see like crazy.
So...my 1 thing that made me a better glasser, was choosing an appropriately magnified bino for the way I hunt.
