Zeiss Terra ED 8x42

With its fiberglass-reinforced, waterproof casing, the Terra ED fulfills the high expectations of the outdoor enthusiast. The Terra ED line is designed to be compact, light, and sturdy. This means: the Terra ED is the ideal companion that weighs little, fits easily into every pocket, and is almost indestructible.

Whether on long journeys, in the open countryside, at racetrack or concerts, on city tours, in the mountains or on the open seas.

The green 2017 edition of ZEISS Terra 8 x 42 ED Binocular features a redesigned ergonomic chassis that makes holding them more comfortable, especially during long glassing sessions. Optically, they retain the exceptional elements that are the hallmarks of the Terra ED including compact Schmidt-Pechan roof prisms, SCHOTT extra-low-dispersion (ED) glass, and the proprietary multi-coatings.

These complementary technologies and elements work together to produce an immersive observational experience that presents clear and bright views, with accurate colour representation and virtually zero distortion, across the entire field of view. Adding to the binocular's usability is a short 5.25-foot close-focus distance that gives them the ability to resolve feathers or leaves in fine detail.

The comfortable ergonomic chassis is made of a fiberglass-reinforced polycarbonate to help reduce weight, without sacrificing strength while adding impact and temperature resistance.

Being resistant to temperature changes not only ensures that the housing will remain a constant temperature, even in cold and wet conditions, but will not experience the expansion and contraction common in metal chassis that can cause the optical elements to move out of alignment over time and preventing the binocular's ability to achieve sharp focus. The ZEISS Terra 8 x 42 chassis is covered in black rubber armouring that helps to protect it from drops and impacts and provides a slip-resistant grip.
