About this product
When tactical operations take place in challenging conditions – and they always do – these are the optics to count on. Proven on missions from extreme darkness to high-altitude sun, arctic cold to desert heat, they give you exactly the optical capabilities you need: mid-90% light transmission, image clarity from edge to edge, belly crawling toughness, even integrated compass, range-finding or custom reticles, and laser protection if desired. When your mission demands optical superiority, now you have it with the Steiner 10x50 binocular.
Binocular Features
• Floating Prism System uses flexible silicon lens mount to absorb severe shock, impact and abuse without damage
• Multicoated Optics are state-of-art for brighter picture, higher contrast and sharply contoured images with natural color definition.
• Sports-Auto Focus™ System lets you focus each eyepiece to your vision once, then keeps images razor sharp from 20 meters to infinity. No more chasing focus on moving objects.
• N2 Injection™ system seals 14-psi pressurized dry nitrogen into the optic, for fogproof clarity in any condition - from artic cold to desert heat.
• Cylindrical Eyecups shield the eyes from sun, grit and wind, and can be folded down for viewing with sunglasses or gas masks.
• NBR Rubber Armoring is durable, slip-proof and noiseless to ensure secure, chassis protecting grip in all conditions.
• Makrolon® housing is durable polycarbonate with NBR Long Life rubber armoring, creating a lightweight, rugged chassis that withstands 11 Gs of impact. Impervious to harsh conditions for generations of trusted use.
• Ranging Reticle a versatile ranging reticle found on all "r" models that can be used to judge both the height and distance to a target.
• Waterproof up to 5 meters. Pressurized nitrogen-filled tubes resist water intrusion even when submerged.
