I have an old pair of Geovid (7 by 42) that I purchased at least 12 years ago and they haven't ever let me down. They have a great warrenty, I had a horse go down in a river one day and the glasses were damaged and filled with water. At the time I was a guide on a goat hunt, the next day I called Leica and they had a new pair fedex to me the next day. Can't do any better than that. I use them all the time and the range finder seems to work good out to about 1000 yards maybe 1200 if conditions are right. They are a little on the heave side, but I can live with that. Last year I ranged a 6 pt. bull at 738 yards and made one shot with my .408 chey tac. Again, best glasses I've ever owned.
