I've used a bunch of them and used to buy or trade for a different one every year or so. Until I bought a Leica CRF 1600-B when they came out a couple of years ago. I love it. I have no desire to trade for anything any different. It's a keeper.
It's performed flawlessly for me in all types of weather. Basically, if I can see it, I can range it, if whatever "it" is is within a mile or so.
Edited to say that I have NOT tried any Zeiss rangefinders, so I have absolutely no experience with that brand. They might be the cat's azz, but I've never touched one and have no friends that have one.
