I have been using the same pair of older American made Burris Signature 12X50s for about 20 years. Stellar glasses. My dad runs a pair of Swarovski 10x42s that I bought him for Father's Day one year and sometimes when we are hunting the Burris slightly outperform the Swaros.
It is a shame Burris went overseas, as their American made stuff was pretty good back then.
