Attach the padded neckstrap to the binocular in
three simple steps. Begin with the right barrel of the
binocular and repeat the process for the left barrel.
The Neckstrap
1. Push a few inches of the strap
through the neckstrap attachment
point on the binocular.
2. Loop the strap over the
attachment point, then thread the
strap through the strap buckle.
3. Secure the end of the
strap by slipping it
through the strap loop.
IPD
The eyecups on a Diamondback binocular twist up and
down so any viewer can take advantage of the long eye
relief and enjoy comfortable, full-field viewing.
With eyeglasses or sunglasses,
retract the eyecups.
Without eyeglasses or sunglasses,
extend the eyecups.
Adjusting the Eyecups.
The twist-up eyecups are built on a solid frame, tapered
to fit the contour of the eye, and covered with rubber.
Adjusting the Interpupillary Distance.
The interpupillary distance (IPD) is the distance
between the centers of the left and right eye pupils.
Match the IPD of your eyes
to that of the binocular by
rotating the binocular barrels
inward or outward until you see a
single image that is free of shading.
