I am using some Nikon 10x42 Monarch binoculars and their OK. I am thinking of steping up to a Steiner or Zeiss. I did look through a pair of Steiner and some Swarovski, one after the other and I could not see a lot of differance. I have not looked through the Zeiss. I want 12 power or more. What do you guy's use? Bill Maylor.
