Delta Optical Chase 8x42 ED Binoculars

Compact 8x42 binoculars in Schmidt-Pechan roof system with silver-coated reflective layer. The lenses have multi-layer anti-reflective coatings, which allow for a sharp and bright image even in bright sunlight. The lenses use low-dispersion ED glass.

The binoculars are equipped with an inner focusing mechanism. Dioptric correction takes place through the movement of internal optical elements, providing greater tightness. In addition, the space between the optics has been filled with nitrogen.

The binoculars are in the form of a compact body, easily fitting into a small bag or even a larger pocket. The body is covered with rubber, which guarantees a pleasant and comfortable grip in the hand. The comfort of use is enhanced by rubber eyecups with three degrees of extension.

It is ideal for wildlife observers, hunters, ornithologists or lovers of walks in the woods.

The kit includes a carrying case, optics care cloth, and eyepiece and objective lens caps. The binoculars are covered by a 10-year manufacturer's warranty.
