Leupold 182883 BX-4 Range HD TBR/W 10x42mm Rangefinding Binoculars

When speed is paramount, there’s no substitute for a range-finding binocular. The BX-4 Range HD TBR®/W 10x42mm fuses our DNA® engine and ballistics software with the optical performance diehard hunters and shooters demand. Now you can spot and range targets without wasting valuable seconds switching between gear. Its high-contrast red OLED display delivers visible readouts in any light, and its edge-to-edge clarity makes glassing sessions easy on the eyes. The next time you’re packing for a match or hunt, cut the excess. Take the BX-4 Range HD TBR/W.

This time-saving combo of tech and glass is built around our Elite Optical System. It delivers excellent dawn-to-dusk light transmission for a bright image when it matters most, elite-level glare reduction in harsh light, and the resolution and clarity you can count on in the backcountry. Compare it to other range-finding binoculars in its class, and you’ll see a difference, especially in low light.

But that’s just half of what this optic is all about. Its 10x magnification provides a large field of view for glassing in tight areas while still being powerful enough to make positive IDs from a distance. And when you finally spot your target, one press of the power button will tell you exactly how far to send your rounds. Backed by our Lifetime Optics Guarantee and a Two-Year Electronics Guarantee, the BX-4 Range HD is built for years of performance.
