Properly Focus the Binocular
For the best optical performance, follow
the two-step process below to properly
adjust the center focus and diopter of the
binocular.
Choose an object that is roughly 20 yards
away from you and stay in the same spot
until you have adjusted the binocular for
your eyes.
1. Adjust the center focus (E) - start by
closing your right eye or covering the right
objective lens with your hand.
Focus your left eye on the object and adjust
the center focus wheel until the image is in
focus. Leave the center focus (E) in
this position as you
adjust the diopter (A).
