72030 SkyMaster Pro 15 x 70 Porro Prism Binoculars, Black

Featuring large objective lenses, BaK-4 prisms, and fully multi-coated optics with proprietary coatings, these binoculars deliver exceptional viewing performance for their price point. The unique detachable RSR (Reflex Sight Ready) rail allows for the mounting of an optional red dot finderscope or other reflex sight, making it easier to point at astronomical or land-based targets. Every lens surface is coated multiple times with unique coatings to improve color, contrast, and maximize brightness, resulting in sharper and brighter images even in low light. The durable body features a rubber-armored, polycarbonate housing that protects against damage and harsh weather. It is fully waterproof and nitrogen purged to prevent internal lens fogging.
