I have looked through Swarovski binoculars and they definitely have a wow factor. As others have said, just too expensive for me.
I have several used Nikons which were at one time top of the line. An old 7X50 Polaris with very worn leatherette but the optics are perfect. The range finding reticle is probably useful but I am getting too old to do the math in my mind.
I got an Army surplus Steiner and they also have the wow factor. A lot less expensive than the Zeiss etc.
As for Scopes, Leupold are the best for the money.
I have a pair of the ultra high dollar Zeiss 10x56 binos. There is a difference, but there are a bunch that are close to being as good that are in the $500-$750 range.
I won mine in a sales contest, that was the only way I can justify having them. At daybreak and dusk, they are fantastic. The rest of the day, I use a pair of higher end Bushnells that I acquired in a gun trade, paid $375 for the rifle, kept it 10 years, then got the binos and $600 for it, they are lighter to pack than the huge Zeiss glass.
I was doing some research and discovered that my Nikon 7X50s are actually the model called “Tropical”. They look just like a WWII era Navy Bausch & Lomb but the optics are even better.
The 6X30 are of the exact same construction.
