BASIC OPERATION
Adjust the Eyecups
The eyecups on a Vanquish®binocular twist up and down so any
viewer can see the full field of view and enjoy comfortable
viewing—with or without eyeglasses.
When not using eyeglasses or
sunglasses, keep the eyecups
fully extended. For the best
viewing when viewing through
eyeglasses, twist eyecups down.
Adjust the Interpupillary Distance
The interpupillary distance (IPD) is the distance between the centers
of the left and the right eye pupils. Match the IPD of your eyes to the
binocular so that you see a single image free of edge distortion.
IPD Rotate the binocular barrels inward
or outward to line your eyes up with
ocular lenses.
Distance between the centers of
the ocular lenses.
Focus the Binocular
The Vanquish®binocular is
equipped with a single
diopter on the right-hand
barrel. For best views,
follow this two-step
process to properly adjust
the center focus and
diopter. Choose an object
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. Look
through the left barrel and adjust the
center focus wheel until the imagine is in
focus. Leave the center focus in 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 the
right barrel and adjust the diopter until
the object is in focus. Make note of the
position of the diopter setting in case
you need to set it again. From this point
on, you will only need to use the center
focus wheel.
Caution: Binoculars are not intended for looking at the sun, or any
other intense light source. Such viewing can damage your eyes to
the point of causing blindness.
