Congratulations on your purchase of a Diamondback
binocular—a great value for any outdoor experience.
Binoculars are not intended for looking at the sun, or any other
intense light source. Such viewing could damage the retina and
cornea of your eyes—even to the point of causing blindness.
Caution:
The
Binocular Series
D IAMONDBACK
The bright images you’ll see with a Diamondback
binocular are the result of fully multi-coated optics,
working to increase light transmission throughout the
optical system. Phase correction, a coating on the prism
surfaces, further improves the color fidelity, quality, and
contrast for sharp imaging that is especially noticeable
under low light conditions.
