Properly focus the binocular
For the best views, follow this two-step
process to properly adjust the center focus
and diopter. Choose an object that is about
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—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 in this position
as you adjust the diopter.
2. Adjust the diopter—start by closing your left eye or covering
the left objective lens with your hand. Lift the diopter ring to
unlock and, looking through your
right eye, adjust the diopter so that the
object is in focus. Make note of this
diopter setting in case you need to set
it again. Push the diopter ring down to
lock—from this point on, you will only need to use the center
focus wheel.
