Outdoor enthusiasts know that durability, size, weight and optical performance are necessities when in the field.
Sightron has added 2 models to the popular SII Blue Sky line of binoculars. The 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 SII Blue Sky binoculars are ready for all jobs from bird watching, to hunting or viewing the night sky.
Features :
- 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
- Waterproof: Rain, snow or humidity, Sightron optics are built using 100% sealed system ensuring a lifetime of performance in the most extreme environmental conditions
- Nitrogen Gas Charged: Nitrogen filled to provide a lifetime of use from fogging and internal water buildup
