The Leupold BX4-Range HD Gen 2 TBR/W 10x42 rangefinder binocular merges spot-and-stalk hunting with on-board ballistics in a single optic. Instead of glassing with one tool and then reaching for a rangefinder, you get a 10x42 binocular that ranges targets out to 4000 yards on reflective surfaces—or 2000 yards on trees and natural terrain—while simultaneously delivering True Ballistic Range/Wind (TBR/W) calculations. That means you can dial your shot solution without ever lowering the glass. The high-contrast red OLED display reads clearly in low light and bright sun alike, and Leupold's HD optical system keeps the view edge-to-edge sharp so longer glassing sessions don't wear you out.

What sets these apart is the ballistics engine built in. TBR/W mode gives you a hold point for a 10-mph wind out to 800 yards, accounting for angle and distance. Bow Mode handles archery hunting out to roughly 70 yards with sub-20-degree angles. Archer's Advantage mode takes arrow weight, velocity, and peep height into account for steep-angle or distance shots. Last Target technology prioritizes the farthest object in the laser's path, cutting through rain, snow, and fog that would fool lesser rangefinders. Line of Sight mode measures straight-line distance regardless of slope.

Built rugged and user-friendly: interchangeable eyecups (winged, medium, or low-profile for glasses) let you dial in comfort. Easy-grip standoffs make button location intuitive even through heavy gloves and prevent accidental activation. The 1/4-20 tripod-ready port accepts any standard tripod. Waterproof and fogproof sealing keeps internals dry across temperature swings and elevation changes. The optical system delivers strong light transmission and glare reduction for reliable dawn-to-dusk use.
