Design features of binocular BKC 20х50 with stabilization
Binoculars Farvision BKC 20х50 equipped with image stabilization system, which compensates (suppresses) vibrations of the sighting axis that occur during observations with the movable base, or a longer observation with it. The angle of correction of the fluctuations in the housing is +/-6°. Thus for the proper functioning of the stabilizer does not require a power source (battery), as the inertial stabilization system is enabled by changing the position of the lever located in the lower part of the body. The instrument does not generate acoustic noise during operation, not distracting and not unmask the observer. You can conduct a panoramic observation without loss of image quality.
This model is made in high impact plastic case, well protected from mechanical damage, dust and moisture. Ribbed inserts of rubber on the sides of the casing ensures easy hold and grip during observation or transport. It is also worth noting that the binoculars Farvision BKC 20х50 stabilization operates in a wide temperature range of -40°C to +50°C.
The user is able to configure the device under base eyes, to fine-tune the sharpness (split system focus) and diopter correction.
