Properly Focus the Binocular
For the best reults, follow this two-step process to properly
adjust the center focus and diopter. Choose an object about
20 yards away 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. Look through your right
eye and adjust the diopter ring
(found on the right eyepiece)
until the object is in focus. Make
note of this diopter setting in case you need to set it
again. From this point on, you will only need to use the
center focus wheel.
