Hi, I have used PVS 14 forever, but now am trying out a BNVD. I'm a little confused as to the recommended process for setting focus and diopter, as it is different from any other two eye optic (binocular) I have used. My instinct is to focus each eye to infinity with the objective lens, then to tune each with the diopter. Is this correct, or is there a better system to use? Many thanks.
