I just got a BR2 rangefinder from a friend and had a quick test run with it. Admittedly I didn't spend much time with it, but I did test it side by side with my Zeiss range finding binos. What go me was that unless it had a very good, clean target it would not range. For example off a hillside covered with forest I could jot get a reading, while the Ziess had no problems. Also I could not get reading off anything past about 800 yards. I found the length of time needed to get a range to be a little long too, again, the Ziess is almost instant or close enough. So what gives? Is this what I should have expected or is there possibly something wrong with this particular unit?
