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.

Protect Lenses While Out in the Field

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.
