Delta Optical Forest II 10x42

Binoculars with high magnification of 10 x, objective diameter of 42 mm and angular field of view of 6.8°. Designed for nature-tourist observation, including focused and distant objects. The optical system consists of 8 elements arranged in 6 groups, and the design uses high-quality BaK4 glass prisms . Filling the construction with nitrogen prevents the lenses from evaporation.

The prisms are coated with phase coatings and silver, which ensures a sharp and bright image. In addition, all lenses are covered with high-quality anti-reflection coatings. Thanks to them, the binoculars are characterized by high light transmission and neutral image colors. Well-etched interiors of the tube prevent the appearance of unwanted reflections and so-called ghosting in the image.

All Forest II series binoculars are equipped with a central focusing knob and individual diopter correction in the right eyepiece. The plastic Twist-Up eyecups slide out, allowing the binoculars' eyepieces to be comfortably adjusted to the observer's individual needs.

It is worth mentioning that the binoculars are able to withstand even the harshest weather conditions. The sealed housing allows the model to be used freely in wet terrain and in the rain, and the binoculars can even withstand immersion in water up to a depth of 1 meter for 5 minutes.

Included:
- case,
- binocular strap,
- strap for the case,
