RvW - I'm a Zeiss fan as well. I've had 2 Diascope spotters and they've been fantastic! Currently I have a 85MM Diascope, and it's great for the open country we hunt.

When the boy was 11yo, he saved his money and bought a close-out Zeiss 4.5x14 for his Mdl 70 pre-64 .308 that was my great-grand fathers. He's 4-4 with it on deer (3-3 on bucks), including a 406 yard shot. It's clearer than my VX-3's.

I've heard the Sig RF has quite the following. For me, I wanted one less thing in my pocket or around my neck. I think the Leica warranty on my Binocs is 5 years. Everyone prefers lifetime warranties, but I decided if they were going to chit the bed they'd prob do it within 5 years? It's been 3 years now??? and now probs yet except the eye cups crack. Leica has been great about replacing them, and I think I figured out why they crack. I have a pretty good supply of them now.
