10X32 Terra Ed Binocular

Zeiss's 10x32 Terra ED Binocular combines SCHOTT ED extra low-dispersion glass elements and a compact weather-sealed housing to create a multi-purpose optic that delivers the image quality and streamlined silhouette for birders and hunters a set of smaller glasses that do not sacrifice twilight performance or functionality. At the core of Terra ED are fully multicoated optical surfaces designed to eliminate chromatic aberration, maximize light transmission and render contrast-rich images. They also boast the ability to focus down to 5 feet, allowing observers to get up close to the bird or other nearby subject of interest. Thanks to the space-saving Schmidt-Pechan roof prism design and lightweight composite housing, this binocular weighs just over a pound.

Complementing the high-transmission optical path and modest form factor, the Terra ED has a nitrogen-filled housing that provides fogproof performance and has been tested to withstand submersion to 100 mbar of pressure. This water and fogproof performance, coupled with a broad operating temperature range, enables these binoculars to stand up to almost any outdoor observational situation. A textured center focus wheel and twist-up rubber eyecups supply additional handling features that enhance the overall ergonomics and help make it a full-featured binocular for close to mid-range use.
