One thing I didn’t read in most posts is the ability of the glass you are using to remain fog free. I’ve owned spotters from Zeiss, Swarovski, and Leica and never had a fogging problem . Looking through spotters all day can be tiring, here is where I feel you get the most benefit from the expensive glass. Next would be Binos , I have been happy with the mid line Leica Trinovids 10X40’s three sets in 15 years, they are rugged, pretty clear and they don’t fog up. Probably my next upgrade in Bino’s will be to range finders. Rifle scopes are only used when it is time for the shot, not fogging , being rugged and reliable is the most important for me. I don’t spin dials. I have new model S&B’s in 3-12X50, 1.5-6X42 , 1.1-4 ,and older Leica & SB that has been all over , they have been well worth the extra money. I have purchased duplicates of my favorite Leica and S&B scopes .I have used Leupold Vari X3 on many important hunts and find them rugged, reliable and fog free. I live on a mountain with lots of various lighting conditions, I compare glass frequently . I am really surprised how well Leupold Vari X3 scopes compare to the European scopes. For me the Leupold Vari-3 line is base line for a quality scope . A lot of people (birders, sporting enthusiasts, hunters) are always changing gear and upgrading. There is a pretty good market of lightly used high end glass That offer some great deals. Usually you can tell what kind of use and care a optic has had by simply looking at its cosmetic condition .
