I have had Zeiss RF's for 4 years or so now...They are great binos. They bring up ranges immediately. I have ranged out to 1700 yards...Cant really tell ya how close though, 15ish or so. In all honesty, for bow hunting, I have a Leupold handheld for single hand use that i pack with me along with my zeiss binos. It is a lot easier to have a small one handed use RF for close bow hunting scenarios that using the binos. . The only negative I have with my zeiss, is im not to big a fan how they designed the eye cups, which may have been redesigned by now, and they are hefty, so you want to make sure to have a good bino carrying system. The zeiss dont have a true Angle compensation feature, you can program 5 different ballistic profiles into them that correlate to the majority of common rifle calibers, and then up to 600 yards it will tell you the exact drop of the bullets. . If you are dead set on angle comp, you will probably have to go with swaros, but when it comes to shooting long distance at angle, you just need to know your ballistic profile and how your rifle shoots, and remember to hold for less yardage.
