I have Leica 10x42 Geovid HD-B binos that are very very nice. I haven't looked through any 10x binos I think are any better including the Swaro SLC and Leica Ultravid. They will range to 1400yds very reliably on trees, rocks, and other larger more solid objects. I've never had trouble ranging deer inside 900yds. Often they will range stuff up close to 2000yds in good conditions.
I also have Swaro SLC HD 15x binos. I've never used the big Leicas, but these are great glass. I can't think that the Leicas would be any better.
Get the big Swaros on a window mount or tripod and they are awesome. I have an Outdoorsmans tripod and mount I use, I like their quick release and pistol grip head so I can switch between optics and tripod or window easily.
