Customizing the hurri Cane
Adjust the eyecups
The soft, rubber eyecups on a Hurricane binocular provide comfort,
folding up and down for viewing with or without eyeglasses.
For the best viewing
through eyeglasses, fold
the eyecups down. When
not using eyeglasses or
sunglasses, keep the
eyecups fully extended.
Adjust 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 so that you see a single image that is free of shading.
IPD
IPD is the distance between the
centers of the ocular lenses.
Rotate the binocular barrels
inward or outward to line your
eyes up with the ocular lenses.
