Re: leica 1600b or Zeiss rangefinder
I own both and feel there has been an accurate discussion. It comes down to what your priorities are. the Ziess is less expensive, has better glass, 8x vs 7x magnification, it is easier to hold stable and the "button release" method of ranging is better than the Leica "double punch" method.
despite all of those advantages for the Zeiss, I use the Leica 1600 since it's smaller beam divergence does a much better job of ranging whitetails past 480 yards.
thus for less than 480 yards, I'd reccomend the Zeiss; however, mine is simply not effective at ranging whitetails beyond 480 yards.
used to have a Swaro. to me, the Swaro is a virtual twin to the pros/cons of the Zeiss, just costs a lot more and its push button is difficult and disruptive to a steady hold.
