Leupold BX-4 Range Gen 2 Rangefinder Binoculars

At 37 ounces, these binoculars are heavier than a standard pair of 12x50 glass, but they replace the need to carry a separate rangefinder. This trade-off is generally worth it for backcountry hunters who prefer a streamlined kit over carrying two distinct devices.

With an eye relief of 14mm, these binoculars are usable with glasses, though it is tighter than some dedicated birding optics. You may need to adjust the eyecups down to find the full field of view, so it is worth testing them with your specific eyewear if possible.

The unit runs on a single CR2 battery. These are compact and widely available, making them easy to pack as a spare, though the battery compartment is designed to be secure and weather-sealed for field use.

TBR/W (True Ballistic Range/Wind) calculates the angle-compensated distance to your target, which is essential for shooting uphill or downhill. It provides a precise shooting solution so you don't have to manually calculate holdovers for steep terrain.

Yes, the 50mm objective lens is specifically designed to gather more light, which significantly improves visibility during the critical dawn and dusk hours when game is most active.

Leupold offers a lifetime guarantee on their optics, which covers defects in materials and workmanship. If the product fails due to these reasons, they will repair or replace it, regardless of whether you are the original owner.
