DCF BC features high-performance optics, a waterproof construction allowing fresh-water rinsing, and an ergonomic body design for a comfortable hold. An additional coating (silver-deposited) is applied to the auxiliary prisms to further enhance light transmittance. Combining outstanding optical performance and value with a compact, lightweight, carry-anywhere body, these new models may be used in a wide range of applications including nature observation, bird-watching, sports viewing, hunting and more. The new DCF series features an open-bridge configuration for a firm, comfortable hold. Protected with a rubber housing that features slight indentations for the user's thumbs, each model offers stable, fatigue-free observation, even while users continuously track a moving subject during extended observation.
