B1™ ED/HD Binoculars

[ OVERVIEW ]

The B1™ binocular uses the finest ED (Extra-Low Dispersion) glass, and has amazing HD (High-Definition) performance. You have purchased a premium binocular for a lifetime of reliable use.

All lenses are fully multi-coated with our proprietary Diamond Bright coating for maximum glare reduction and light transmission, giving the viewer a satisfying, color-saturated view and exquisite optics suitable for long term, comfortable glassing of objects near and far. The BAK-4 internal roof prisms are treated with cutting-edge phase-corrected dialectric coatings that limit dispersion and help minimize diffraction. The generous eye relief means enjoyable viewing for eyeglass wearers, and the remarkable close focus capabilities mean that a backyard bird or butterfly can be as sharp and in focus as a distant animal or galaxy. The magnesium body shaves weight and adds superior rigidity, while allowing a pleasing and ergonomic grip for any sized hands.
