Consequently, it can be used just as easily as the single-hinge Zeiss Victory design.  If you focus w/ your  right hand, fold the right side out all the way, then adjust the IPD by unfolding the left side the correct amount while looking though the binos.  As a bonus, this technique places the focus knob so that it can be rolled efficiently with the pad of your finger instead of the tip.  --AP</blockquote>
