Futurus binoculars. Stereoscopic image
Based on Porro prism optical scheme, the Yukon Pro binoculars feature compact dimensions. A wide space between optical axes of the right and left optical channels provides better three-dimensionality as compared with binoculars designed on other optical schemes.
Eclipse™ lens caps
The Eclipse™ lens caps are incorporated in the Futurus' protective rubber armor body to prevent their loss. The objective lens caps can be thrown back on the binoculars' body, fitting closely on it without disturbing observation. The lens caps rotate for 360 degrees about the optical axis. The cap can be fixed in open position inside of the body between the optical channels.
Water-resistant body
The Futurus Pro's body is made of shockproof carbon-filled plastic featuring mechanical stability. The binoculars’ body is rubber armored, lightweight and compact and guarantees comfortable grip.
