Description

Levenhuk Sherman BASE 10x50 Binoculars are a multifunctional optical device for observations in extreme conditions. These binoculars are dustproof, stay safe in hard rain or snow, and survive falling from low heights. The powerful optics allow observing distant objects, nature and city landscapes in maximum details. The binoculars can be installed on a tripod, which makes them comfortable for longtime static observations.

The optics are protected from bad weather conditions with a waterproof aluminum body. High humidity or rapid change of temperature cannot interrupt your observations – the binoculars’ body is filled with nitrogen and prevents the lenses from fogging. The coated optics give you a sharp and contrast image, and the wide field of view allows observing extended areas. With Levenhuk Sherman BASE 10x50 Binoculars it is easy to follow moving objects.

All the parameters can be set up to your specific needs. The diopters are adjustable with a ring on the right eyepiece. In addition, you can adjust interpupillary distance and the sharpness of the image. If you wear glasses, you can twist up the eyecups, or pull them out to protect the image from side light.
