With a magnification and objective lens combination favored for its versatility, even in challenging light, the Opticron 8x42 DBA VHD+ Monocular is an ideal companion for those who spend their time in the field or at the range. The DBA is outfitted with anti-reflection fully multi-coated extra low-dispersion glass and phase-corrected dielectric-coated roof prisms to deliver bright and clear high-contrast images that are free from comas and fringing with accurate color fidelity. For those who want to observe small insects, bugs, birds, flora, and fauna the DBA is engineered with a short 5-foot close focus distance.
Complementing the optical performance are construction details that will help it withstand the rigors of the outdoors. The optical tube is nitrogen-filled and O-ring sealed to be waterproof and submersible to a depth of 5 feet, while also being resistant to internal fogging when moving through extreme changes in temperature or environmental conditions. The tube is wrapped in a protective rubber armor that provides a slip-resistant grip in cold and wet weather. Weighing under 12 ounces and measuring less than 6 inches in length, the DBA VHD+ will easily fit in a pack or pocket without adding excessive bulk to make it an invaluable addition to your kit.

- Roof prism optical path ensures a slim and compact form factor
- Phase-correcting prism coatings eliminate internal interference to improve color and contrast
- Dielectric-coated prisms deliver greater than 99% light transmission across the entire visible spectrum resulting in increased brightness and clarity
- Extra low-dispersion (ED) glass lens elements reduce chromatic and spherical aberrations for increased contrast, and improved color rendition and sharpness without distortion across the entire field of view
- Proprietary S-H anti-reflection fully multi-coated optics maximize light transmission and improve contrast and color fidelity across the entire visible spectrum
- Short 5-foot close focus distance allows for detailed observations of small insects, bugs, flora, and fauna
