Focusing the Binocular
Choose an object that is about 20 yards away from you
and follow this two-step process to properly adjust the
focus. Be sure to stay in the same spot until you have
adjusted both the center focus and diopter.
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 center
focus dial) 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 only need to adjust the center focus.
Maintain the optical brilliance of the Vulture binocular by
keeping the lens surfaces free of dirt, oils, and dust.

Caring for the Lenses
Make use of the rainguard and tethered objective lens
covers to protect the lenses when not viewing. Store the
Vulture binocular in its carry case.
Keep Lenses Clean
Along with normal use comes the need to clean the
binocular lenses. Follow these guidelines for cleaning:
1. Remove any dust or grit from lenses before wiping. Use
a can of pressurized air or soft camel hair brush (acrylic
optical brushes also work well).
2. Clear lenses of smudges, fingerprints, or eyelash oil.
Fog the lenses with your own breath and wipe with
the non-abrasive lens cloth included with the Vulture
binocular.
Cleaning
fl
uid and optical paper can also be used. However, you
should never use facial tissue, heavy cotton, or
fl
annel clothing on
lenses—these materials can scratch the lens surfaces.
