The rubber coating makes the binoculars easy to grip and protects against moisture such as dew, fog, and light rain. With the 11x magnification, you can bridge long distances and bring the night moon and starry sky close. The high-quality BAK-4 Porro prisms provide a high-contrast, color-accurate image. The large objective diameter of 70 mm allows a lot of light to enter, and the fully multi-coated front lenses ensure sharpness even at the edges. Focusing both eyepieces is done via the large central wheel. The diopter adjustment and foldable eyecups are ideal for glasses wearers. Due to the high magnification, we strongly recommend using a tripod for shake-free observation (optional available from DÖRR). Unscrew the cap below the central wheel - underneath is a ¼” tripod thread. Porro binoculars. Bring distant objects up close.
