Leica makes excellent rangefinders, for sure, but they don't do angle compensation yet, even in the new 1600. If you're an archer I wouldn't get that one. They'll show you the angle, but that doesn't help much in the heat of the moment. If you're a riflehunter, it wouldn't be as big of a deal.
Leupolds units aren't waterproof, and won't do archery ranges past 60 yards.
That leaves Bushnell and Nikon. Nikon makes a better rangefinder right now. Look at the new riflehunter 600 or the archer's choice max.
