Sleek and stylish with a gray body and black accents, ZEISS's 8x25 Terra ED Compact Binocular gives you a competent and compact optic that fits easily in the palm of your hand and looks good while it's there. A combination of technologies work together to produce bright and clear images with increased contrast and true-color rendition. They include: Schmidt-Pechan roof prisms, SCHOTT extra-low dispersion (ED) glass, and anti-reflection fully multi-coated optics. The Terra ED is offered here in an 8x power, which provides a nice general-purpose magnification with a generous field of view.
The lightweight housing is nitrogen filled and O-ring sealed, enabling it to withstand use in wet and snowy weather, and the rubberized armor offers protection from impacts while providing a slip-resistant grip. The Terra's double-hinge closed-bridge design allows it to fold compactly for an easy fit in most pockets or packs, while the knurled center focus wheel enables fast focusing. Twist-up eyecups make it comfortable to use with or without eyewear.
