I had leica hd b.. Went back to stand alone leica 1600 b and my swaro binocs. I just refuse to sacrifice optics quality for rangefinding even as convenient as it is to have both in one unit. For less demanding viewing i could make a combo work.
That's pretty much my opinion as well having used the Lieca too... not to mention the expense, size, complication of having an all-in-one unit that can fail. Electronics can and do fail.
Keeping them separate is KISS.
