(OWTOADJUSTFORDISTANCEBETWEENYOUREYES The distance between the eyes, called “interpupillary
distance,” varies from person to person. To achieve perfect alignment of lens to eye, follow these simple steps:
1. Hold your binoculars in the normal viewing position
2. Grasp each barrel firmly. Move the barrels closer together
or farther apart until you see a single circular field.
Always reset your binoculars to this position before using.
2OOF0RISM3YSTEM the prisms overlap closely allowing the objective (front)
lens to line up directly with the eyepieces. The result is a slim, streamlined
shape in which the lenses and prisms that magnify and correct the image
are in a straight line.
0ORRO0RISM3YSTEMS the objective lens is offset from the eyepiece.
Light is redirected through the binocular internally. The result is a shorter,
stockier shaped binocular. In general, porro prism binoculars offer a wider
field of view. Most zoom binoculars use the porro prism system.

Most binoculars have a center focus wheel and an independent right diopter eyepiece to account for
small differences in the strength of each eye. Please follow the steps below to focus properly:
1. Adjust the interpupillary distance.
2. Rotate the right eyepiece to its index mark and sight on a fixed distant object.
3. Cover the right objective (front) lens with your hand, then rotate the
central focusing wheel until the image in the left eyepiece is sharp.
4. Cover the left objective (front) lens with your hand then
rotate the right eyepiece until the image is sharp.
(Note this setting for future use.)
5. Image should now be focused to
your individual eyestrength.
