Focus your binocular
For the best views, use the center focus and diopter to adjust for
vision differences in each eye. Choose an object that is about 20
yards away from you and perform this two-step process:
1. Adjust the center focus. Close your right eye or cover
the right objective lens with your
hand. Look at the object with your
left eye and adjust the center focus
dial until the image is in focus.
Note: Keep the center focus in this
position as you adjust the diopter.
2. Adjust the diopter. Close your left eye or cover the left
objective lens with your hand and rotate
the diopter ring until the object is in
focus. Note: Be sure to record this setting
so you can go back to it if someone
changes the diopter setting.
After setting the diopter you only need
to use the center dial to focus your binocular. If your vision
changes, you may need to repeat this process.
Accessories
Use the provided eyepiece rainguard to protect lenses when you
are not using your binocular. Between viewing sessions, safely
store your binocular in the case. Note: If the optics are exposed
to moisture, keep the rainguard off and allow the optics to dry
out completely before putting them in the case for storage.
Neckstrap
Securely attach the binocular strap to your binocular:
1. Thread the end of
the strap from the
bottom up through
the strap attachment
loop. 3. Adjust the overall
length and pull the
strap webbing tight
so it is secure within
the buckle. 2. Hold the buckle
and thread the end
of the strap inside
the buckle.
Note: Please do not thread a metal ring directly onto the strap
attachment loop when attaching rings or clips for other after-
market equipment. Instead, use nylon zip ties according to the
manufacturer’s instructions.
