As for the 1600B, it costs barely over half the price and it fits in a shirt pocket, which makes a big diff. when you're covering many miles a day. Am I missing anything?
The main drawback to the 1600 and 1600-B when comparing them to the G7 unit is the ballistic curve calculations. Both Leica's use preset ballistic curves based on commonly used BC curves whereas the G7 can be uniquely tailored to your exact drops from your specific rifle/load combination. If you are shooting out to 6-800 yards, and you are lucky enough to find 1 of the 12 curves that fit your setup then it shouldn't be much of an issue but beyond that they are useless.
I would personally try to find a deal on the 1600, there were some sweet deals about a month ago, and pass on the 1600-B. If you really want a do-all rangefinder the G7 is as good as it gets right now IMO.
