Outdoor enthusiasts know that durability, size, weight and optical performance are necessities when in the field. New for 2019 Sightron has added 2 new models to the popular SII Blue Sky line of binoculars. The new additions will feature High Definition Fully-Multi-Coated low dispersion ED glass. Performance is enhanced by dielectric coatings with Phase coated prisms. No matter the task at hand the new SII Blue Sky binoculars are ready for all jobs from bird watching, to hunting or viewing the night sky.

Phase Coated

Phase coatings are coatings applied to roof prism binoculars to aid in the elimination of light interference caused by intersecting light paths as they travel through the Prism.

Dielectric Coated

Dielectric coatings are thin layers of coatings applied to prisms and arranged in sequence so most of the light is reflected for increased light transmission.

Twist Up / Down Eyecups

Twist-up and twist-down eyecups are standard on all SII Blue Sky models. Simply twist-down for eyeglass wearers and twist-up for non-eyeglass wearers for perfect eye relief.

Fully Multi Coated Lenses

Featuring fully multi-coated lenses throughout, the binocular provides maximum light transmission and superior resolution for edge to edge clarity
