  • 8x Magnification: The Kowa BD-XD 8x56mm Prominar Roof Prism Binocular boasts a formidable 8x magnification, delivering powerful zoom capabilities for highly detailed and close-up views of distant subjects. 
  • 56mm Objective Lens: With its 56mm objective lens, this binocular excels in light-gathering ability, ensuring brighter and clearer images even in low-light environments such as dusk or dawn. 
  • Kowa Prominar XD Lenses: Embark on an unparalleled viewing experience with Kowa's Prominar XD Lenses. Meticulously crafted from eXtra-low dispersion glass, exhibiting characteristics similar to fluorite crystal, these lenses collaborate with a specialized dispersion concave lens. 
  • Schmidt-Pechan Roof Prism Lens and C³ Coating: The binoculars feature Schmidt-Pechan roof prisms designed to reflect light back through the optical path with minimal loss. Complementing this, the C³ coating on the prisms further enhances reflectivity, ensuring bright and sharp images with accurate color reproduction. 
  • Kowa's KR Coating: Facilitating easy maintenance, Kowa's KR Coating is applied to repel dirt and other foreign residues from the lenses. This coating ensures that the lenses stay clean and free of smudges, even after extended use. 
  • All-Surface Multi-Coating: An all-surface multi-coating on the lenses contributes to improved light transmission and reduced glare. This coating enhances the brightness and sharpness of the images, ensuring a clear and detailed view in various lighting conditions. 
  • Waterproof and Fogproof: Built to endure challenging conditions, the housing of these binoculars is waterproof to JIS Protection Class 7 standards, capable of withstanding immersion in water for up to 30 minutes. Additionally, the housing is filled with dry nitrogen gas, preventing internal fogging.
