Zeiss 10x42 Conquest HD Binoculars have a higher magnification that allows concentrating on a more focused subject for greater detail. The golden-mean objective size provides the sufficient light-gathering ability for the twilight zones of dusk and dawn without the added bulk of an oversized objective.Watersports and rainy days won't require leaving this item in the car or backpack. The binoculars are waterproof to 13' and nitrogen filled to provide fog proofing and inhibit any condensation buildup. ZEISS high-quality optics play a major role in the superiority of these binoculars. Multi-layer coating reduces light loss and glare due to reflection, offering a brighter, higher-contrast image and light transmission of more than 90%. High-density (HD) glass reduces the chromatic aberration that appears as unwanted "fringes" of color between dark and bright parts of an image.The LotuTec coating protects the lenses from dust and water. Rain just slides right off the exposed glass. A large center focusing knob is easily accessible in all kinds of weather. The twist-up eyecups feature is a comfort for eyeglass and sunglass wearers and the dioptric adjustment ring allows for individual eye differences. The close focus of an up-front 6.6'/2m means being able to catch the detail in that fluttery butterfly's wing before it disappears into thin air. Apparent angle of view: 66° High-density (HD) lens system provides clear and neutral colors Large focusing wheel and twist-up eyecups add user-friendly functionality Nitrogen purged for fog and waterproof protection to 400mbar or 13' / 4mDurable aluminum construction and a compact 6.1" size contribute to its light 1.6 lb weight Functional temperature range of -22 to 140°F/-30 to 60°C Multi-layer coating provides more than 90% light transmission for good twilight performance Schmidt-Pechan roof prisms work as an image-erecting system and allow for a more compact housing architecture LotuTec protective coating furnishes a clearer view in any weather and makes the optics easier to clean; water just beads up and rolls off the lenses
