Hey, I just received my Leica CRF 1600 Rangemaster in the mail yesterday. I took it out to the range this morning and gave it a go. It is the best rangefinder I have ever used and will last me a long time. I went through many cheap rangefinders throughout the years that have under performed and then failed me. I have yet to not get a range on a target that I could hit with my long range set up. I wish I would have bought a nice rangefinder to begin with and would have saved money, but I am glad that I ended up with this one. I can't believe how small, fast, and how accurate it is.
If you can afford it (I can't but I bought it anyway), go with the Leica CRF 1600 Rangemaster. You will not be disappointed!
