Prismatic Cosina 20-100X70

Description

Designed to resist water and air tight so it can be used in extreme conditions. Even if they are exposed to rain or wind, it is difficult to produce blur or mold inside the optical system even when exposed to splashes of the sea on board a boat, even if they are used in a humid or dusty place. The eyepieces are very comfortable, fold to use with glasses and fold out to use without. They provide comfort and facilitate vision. And what to say about the optics, in addition to being made in Japan, BaK-4, with high luminosity and a large field of vision, are zoom type, which means that by moving the wheel that is between both objectives, you can increase or decrease focus power. Being a robust binocular, it will always be more comfortable to hold it through a tripod that will be a great help to observe the sky in the open sky.
