LEUPOLD BX-3A(R) ALPINEA(R) HD 10X42MM BINOCULAR Built for hunters who push deeper, glass longer, and demand more from their optics, the BX-3 Alpine HD delivers elite optical performance that far outworks its price. Designed around Leupold's Elite Optical System, these binoculars maximize light transmission to provide bright, edge-to-edge clarity and an expanded field of view-so you can pick apart terrain with confidence from dawn to dusk. A lightweight yet rugged magnesium chassis keeps weight down without sacrificing durability, while the enhanced armor texture and ergonomic design ensure a secure, natural grip in any weather.
