The DCF BC 9x32 Binocular from Pentax is waterproof to the point where they can be rinsed clean with fresh water. They are nitrogen filled, insuring a fog free viewing. The open-bridge architecture provides a light-weight, firm, and comfortable hold. Rubber housing with slight indentations for the thumbs helps stabilize and ease the fatigue of long viewing sessions.
Optically these binoculars are silver deposited on their auxiliary prisms for decreased internal light loss while the roof prisms are phase coated ensuring a high contrast, high resolution viewing experience. They are fully multicoated so that all the lens elements have multiple layers on all the air to glass surfaces for a brighter, higher-contrast image with less eyestrain.
The element movement for focusing takes place internally improving the fogproofing and waterproofing sealing. The housing, a compact under 4 1/2 inches square, is fully rubber coated adding protection to the binocular from bumps and bruises. A diopter ring and helicoids eyepieces with 5 click stops permits customization for those who do or do not wear sun/eyeglasses.
