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.
Offers 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 that diehard hunters and shooters demand.
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.
We make sure our optics perform at the highest level in the harshest conditions by ensuring they will survive from -40 degrees Fahrenheit all the way up to 160 degrees Fahrenheit.
From torrential downpours to crossing rivers, you’ll never have to worry about a Leupold binocular leaking or fogging up. Our proprietary gas blend and seals are tested to a 33-foot depth and a multitude of pressure changes.
Last Target mode helps the laser punch through moisture in the air to give you accurate distance readings regardless of the weather.
