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.
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.
Located in the right eyepiece, the range-measuring scale enables you to determine the distance to an object. The range-measuring scale is calibrated to the height of the withers of a wild boar at 0.7 m and the average height of a buck with antlers at 1.75 m. The range-measuring scale is easy to use and can substitute for rangefinder while aiming on medium ranges.
The protective filter is for the use in harsh conditions to shield the objective lenses from dirt, sand, dust, fingerprints, water, and scratches. The orange filter permits yellow, orange and red light beams through. The filter will also enhance the quality of the image in poor conditions such as fog, haze, storm, sand storm, etc.
The eyepiece caps are fixed with help of spring rings. When open, they prevent lateral light exposure. The caps can be removed when adjusting diopters.
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. Moving parts of the binoculars, joints, lens locations have extra moisture protection. Thanks to the IPX4 degree of protection (IEC 60529 standard), the Futurus Pro binoculars can be operated in atmospheric precipitation.
