Short Description:
Legendary binoculars "Secunda" of the Kazan factory. Stunningly volumetric image, depth of field created by binoculars B7x30 received respect and recognition throughout the world.
The binoculars have a unique wide-angle eyepiece design with a swivel-retractable eyecup system.
This model is currently out of production.
Split-focus binoculars are generally more reliable than center-focus binoculars. This is due to the absence of the central focusing unit, which many manufacturers do not pay enough attention to, and often skewing of the image occurs in this place. In turn, the central focusing is faster, but with its own peculiarities. If you plan to use binoculars in the field and extreme conditions, it is better to choose a separate focusing system.
