I picked up a 1600B demo off of Camera Land early last year and am very pleased with it. Fast readings, very nice glass, easy to use. I choose the Leica over the Zeiss because it has a smaller beam divergence. I can range trees, free hand out to 1400ish yards in the first attempt. I have had no trouble ranging ground hogs in open fields out to 500 yards free hand. Looking forward to getting a mount for my RRS TVC-33 and seeing how far and accurate the Leica is.
