Being someone who has used 3rd tier binoculars around $300+; and second tier binoculars in the $1,000ish range in part-time State law enforcement; at each level I was thrilled because I didn't know anything else existed.
When I stepped up from the Steiners to the Zeiss Marines where the latter are probably just not quite alphas but well better than Conquests I thought that was just stunning and they were.
But then one day just outside of Montgomery, Alabama I looked across a massive Bass Pro out the window and to the highway through some Swarovision EL 10X42's and I thought, "are you kidding me?" So now I own an Ultravid HD Plus, and my personal answer to are the alphas worth the extra coin is resoundingly yes.
I don't begin to have the experience or frame-of-expertise most who post on this forum do. I did know those Zeiss Marines permitted me to clearly look right in to a car as they came over a hill, even at dusk, and write the seat-belt ticket as a result.
With the alphas, the law of diminishing returns is undeniably in play, but even so, they are fully worth the price of admission.
