I had a Sig Kilo 2000, wouldn't come close to ranging advertised distances (most don't, but this was worse than most), so I got rid of it. I'd suggest a Vortex, they're one of the few optics companies that warranty their electronics for life too. No questions asked, they'll fix it or send you a replacement. I've got 3 of their scopes and their range finding binos, never had an issue, but i like the peace of mind if something ever happens.
