Interpupillary Distance Adjustment
The distance between the eyes, called “interpupillary
distance” (IPD), varies from person to person. To
achieve perfect alignment of lens to eye, follow
these steps.
1. Hold your binocular in the normal viewing position
and look at an object in the distance.
2. Grasp each of the binocular barrels firmly. Move the
barrels closer together or further apart until you see a
single circular field.
Focusing
After adjusting the interpupillary distance, follow steps
below to focus the binoculars.
1. Close your right eye and look at an object in the
distance through the left eyepiece with your left eye.
Rotate the center focus until image is clear.
2. Close your left eye and look at the same object in the
distance through the right eyepiece with your right
eye. Rotate the right eye diopter until the image
is clear.
3. Look through the binocular with both eyes and image
should be clear, rotate the center focus for any further
image adjustments.
Eye Cups
The binocular is designed with twist up eye cups for
your comfort. To exclude extraneous external light thus

Waterproof / Fog Proof
The binocular is O-ring sealed for complete waterproof
protection to keep the inside dry after contact with
moisture. Fog proof protection is achieved from argon
purging which removes all internal moisture to prevent
anti-fogging inside the optical surfaces.
Tripod Adapter Fitting
The binocular is equipped with a built in tripod adapter
fitting. Carefully unscrew the cover screw located at the
base of the binocular hinge to expose the threaded
mounting socket for the tripod adapter to attach to.
Tripod adapter NOT included.
Care and Cleaning
Care
If handled with care, this binocular will provide years of
trouble-free service. Like any fine optical instrument
your binocular should be given sensible care.
- Keep the lens covers on the lenses when binoculars
are not in use.
- Store binoculars with the eye cups down.
- Avoid banging and dropping.
- Store in a cool, dry place.
Cleaning
- Blow away any dust or debris on the lens (or use a
soft lens brush)
- To remove dirt or fingerprints, clean with a soft cotton
cloth rubbing in a circular motion. Use of a coarse
cloth or unnecessary rubbing may scratch the lens
surface and eventually cause permanent damage.
- For a more thorough cleaning, photographic lens
tissue and photographic-type lens cleaning fluid or
isopropyl alcohol may be used. Always apply the fluid
to the cleaning cloth never directly on the lens.
NEVER attempt to clean your binocular internally or
try to take it apart.
