OUR PRICE $3,399.00

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 our Two-Year Electronics Guarantee, the BX-4 Range HD is built for years of performance.


Leupold’s True Ballistic Range/Wind (TBR/W) technology takes precision to the next level by offering 25 selectable ballistics groups that account for your preferred cartridge, helping you dial in the exact range of your target.

Using the old rifleman's rule on an angled 600-yard shot could result in a 10-15-inch margin of error when compared to the dead-on accuracy of Leupold’s TBR/W. And with TBR/W’s 10-mph wind holds, you’ll have all the information you need to experience more first-shot hits.
