The new 20×70 ED Ultra is the finest mid-size binocular in our product line. The ED (Extra-low Dispersion) glass objectives greatly minimize chromatic aberration, delivering terrestrial and astronomical views free of false-color fringing. Incredible sharpness across almost the the entire field. Very rugged yet relatively-lightweight magnesium-alloy construction, with precise individual focusers. This newest member of the Ultra family has an updated design, with gray rubber armor, with black and red highlights, and captive objective covers. Of course these are fully broadband multi-coated, waterproof, and nitrogen charged. Includes our exclusive Oberwerk Heavy-Duty aluminum-frame case. Also includes the Oberwerk Heavy-Duty L Adapter and neck strap.
