The 10x42 Conquest HD Binocular from ZEISS has a higher magnification that allows concentrating on a more focused subject for greater detail. The golden-mean objective size provides 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. It is waterproof to 13' and nitrogen filled to provide fogproofing and inhibit any condensation buildup.
ZEISS high-quality optics play a major role in the superiority of this binocular. 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.
