The rubber grip on my Swarovski scope's zoom dial broke last week so I called the manufacturer about getting it fixed. They looked up my scope by serial number and I was shocked to find out that I've had my scope since 1991. Time does fly because I didn't realized it had been that long. It's a Swarovski Nova Habicht 3x12-56 and has performed flawless through the years. Anyway, I started talking to the knowledgeable support tech and he said their scopes are way better today. I just wanted to check with everyone here and see if they agree? I would say I've gotten my money's worth out of it since I've had it for 23 years. I don't have any complaints with my scope, but if the glass has vastly improved, I don't mind spending the money on a new Swarvoski. I would also love to know if the Z5 or Z6 is the better way to go for what I need. 90% of my hunting is for Whitetails in MS. Most shots are 20-500 yards, with the average being around 300 yards. There are plenty of opportunities for shots out to 1,000 yards, but I would need to be comfortable consistently hitting an eight inch target at the given range before taking a shot at a deer. Right now I limit my shots to 500 yards. Thanks!
