Have the means to inspect that backyard bird and switch to a sharp and in focus distant animal or galaxy. The B1™ binocular uses the finest ED (Extra-Low Dispersion) glass commercially available and produces stunning HD (High-Definition) images. All lenses are coated with our proprietary Diamond Bright coating for maximum glare reduction and light transmission for a satisfying, color-saturated view suitable for long term comfortable viewing.
The BAK-4 internal roof prisms are treated with cutting-edge phase-corrected dielectric coatings that limit dispersion and minimize diffraction. The magnesium body shaves weight and adds superior rigidity, while allowing a pleasing and ergonomic grip for any sized hands.
