You can’t go wrong with Leica.

I’ve got a Leupold rangefinder but if I upgrade I’ll look at the Sig Kilo since the Leica has a 5 or 10 year (don’t remember exactly) warranty on their electronic optics. Leica binos are top of the line and hard to beat.

I use Zeiss scopes on my Sako and Leupolds on everything else.

My binoculars are the made in Germany Minox. Schmidt and Bender makes the glass for the upper end Minox. I’ve been very pleased with them and are as clear as my eyes can discern. My buddy has Swarovski and they’re also great but pretty heavy. The Swarovski have an edge in clarity but not by enough for me to justify the extra cost. If money was no object I’d go with Leica binoculars and Sig Kilo rangefinder. The technology in glass and coatings have come a long way in the last decade.
