EPOCH Body
The EPOCH offers a single hinge adjustment for fast eye width adjustment,
a Magnesium Alloy body and grip-friendly armor coating making it incredibly
light and durable. In addition, the EPOCH is fully waterproof, dust-proof, and
filled with nitrogen to make interior fog-ups impossible.
Eye-width Adjustment
The distance between the center of the eye pupils is known as interpupillary
distance. Since everyone has a different interpupillary distance, the EPOCH
has a hinge which allows for eye width adjustment.

Optical Quality
EPOCHTM Lenses
All external lens surfaces have a Hard CoatTM anti-reflective coating for
durability, and an anti-fog coating so inclement weather is never a problem.
Ocular lenses are hybrid aspheric for the least distortion of image and color.
The combination of Full-Multi coating on ocular lenses and Flat-lightTM
transmission coated objective lenses work to yield near perfect image
transmission.
EPOCH Prisms
Unique SF prism material combined with next generation phase correction
coating, and AL-HR reflective prism coatings complete a system with near
perfect light reflectivity.
Prisms are secured with five retention screws for extra impact resistance.

Using the Bino Glove™ Lens Covers
Each Epoch Zoom binocular comes with a pair of
Brunton’s custom neoprene Bino Gloves and neck-
strap. The Bino Gloves are designed to protect
your binocular’s lenses, and they are made to be
easily removed or replaced in the field. It is rec-
ommended that you attach the female ends of the
neckstrap connectors to the binocular strap hooks
before placing the Gloves on the binocular. These
female ends can then be squeezed through the
strap connector eyelets on each Bino Glove. If
you need to remove the Bino Gloves while in the
field, they can be snapped to the neckstrap, keep-
ing them out of your way, yet easily accessible.

1. NEVER look directly into the Sun! Severe and permanent eye damage
could occur.
2. NEVER expose the EPOCH protective rubber coating to insect repellant
with DEET! Deet causes deterioration of rubber.
3. ALWAYS supervise children using the EPOCH! The neck strap could
cause strangulation.
4. Avoid extreme temperature changes, and protect the EPOCH lenses from
extreme heat and cold. Do not store in your vehicle.
5. Very carefully remove and replace the eyepieces, when cleaning. The
threads are delicate and could strip if care is not taken.
6. Do not wipe coarse debris off of the lenses. Either blow, or remove it
with a small, bristle brush, in a gentle circular motion.
7. Always wipe moisture off the entire binocular before storing in its
hard case.
8. Storing the EPOCH in its case will prevent damage from dust, debris,
extreme temperature changes, saltwater and high humidity.

Locking Diopter Adjustment
To correct for the difference of visual acuity between your left and right eyes,
the Epoch Zoom is equipped with a diopter adjustment ring. Adjustment can
be made by pulling down the focus wheel and turning the ring left or right,
depending on your needs. After choosing a suitable diopter setting, push the
focus wheel up to lock the ring, preventing readjustment during use.
Variable Speed FocusTM
The EPOCH is engineered with a Variable Speed Focus system allowing you
to focus from infinity to 6 feet in less than one rotation. A varying gear ratio
changes the rate of focus smoothly throughout the rotation of the focus
wheel for quick and precise adjustment.
Left Eye Focus Adjustment
1. Completely cover right objective lens to block all light.
2. Look through binocular at an object at least 100 feet away.
 Do not look through a window, or anything that could cause
distortion of light.
3. Rotate center focus wheel until left eye is
focused on the object, figure 5.
 Object should be a sharp, detailed
image.
4. Remove EPOCH from your eyes, and
uncover the right objective lens.
 Process should take at least 10
seconds to allow your eyes to readjust.

Very little maintenance is required on the EPOCH. However, to obtain the full
optic brilliance of the binocular, both the ocular and objective lenses must be
free of dirt, debris, oil and grease.
EPOCH lens cleaning
Remove large debris particles by blowing on the lenses, or by using a small,
soft bristle brush in a circular motion. Wipe lenses in a gentle circular mo-
tion, using a dry micro-fiber, optic cleaning cloth.
To remove oil and/or grease, use the moisture in your breath, then wipe in a
gentle circular motion, using the optic cleaning cloth.
Household glass cleaners and lens cleaning solutions are not recommended.
They can damage the Hard CoatTM.

Optional Pelican™Hard Case
The EPOCH Hard Case incorporates a neoprene o-ring which makes it a
completely waterproof and dust-proof storage system. It also has an o-
ring sealed, pressure purge valve, for quick equalization due to changes in
altitude or pressure.
For best protection, store the EPOCH and accessory items in this hard case.
