“National Geographic compact binoculars have a attractive, pocket sized design. The fully coated BK-7 optics  and solid mechanics enable a true colour picture replication.


*A diopter, is a unit of measurement of the optical power of a
lens or curved mirror, which is equal to the reciprocal of the focal
length measured in metres (that is, 1/metres). It is thus a unit of reciprocal length

At only 170 g, these water-resistant, rubber-armored binoculars are ideal for tossing in your backpack wherever you travel. Individually focusing eyepieces with BAK-4 roof prisms and multicoated lenses increase contrast and resolution and bring birds and wildlife eight times closer.
