Leupold BX4-Range HD Gen 2 TBR/W 12x50 Rangefinding Binocular
$1,999.99
The Leupold BX4-Range HD Gen 2 TBR/W 12x50 rangefinding binocular combines serious glass with ballistic computing—a real working tool for hunters and long-range shooters who need both superior optics and accurate distance measurement in the field. This isn't a straight binocular with a rangefinder bolted on; it's built around Leupold's Elite Optical System, which delivers the brightness and clarity you need from first light through dusk, plus their proven waterproof and fogproof construction that keeps moisture out and performance in, no matter what the weather throws at you.
The TBR/W (True Ballistic Range/Wind) technology calculates ballistic solutions for shots at distance and steep angles—it'll even generate a hold point for a 10-mph crosswind out to 800 yards. Bow Mode gives bowhunters a dedicated function accurate to roughly 70 yards and under 20-degree angles, while the Last Target feature locks onto the farthest object in your laser's path, cutting through rain, snow, and fog that would fool lesser rangefinders. The straight eyepiece design is practical: it works just as well glassing downhill or scanning through a truck window as it does at eye level, and it packs easier than angled glass. Three interchangeable eyecup sizes and easy-grip standoffs (useful even with heavy gloves) let you dial in comfort and control. A built-in tripod adapter and smooth focusing system round out the package—this is a binocular built for serious use, not fancy optics-case sitting.
Whether you're glassing new country, helping clients close the deal, or dialing in a long-range setup, the BX4-Range HD Gen 2 handles the job with the optical quality and rangefinding smarts that have made Leupold a standard in serious hunting and shooting. Leupold backs every unit with their lifetime guarantee: if it fails, they repair or replace it—no questions, no time limit.

Frequently Asked Questions
What rangefinding modes does the BX4-Range HD Gen 2 have?
Three primary modes: TBR/W (True Ballistic Range/Wind) for rifle hunters shooting at distance and angles with ballistic solutions out to 800 yards; Line of Sight (LOS) Mode for straight-line distance measurement regardless of terrain angle; and Bow Mode for bowhunters, accurate to roughly 70 yards at angles under 20 degrees. The binocular also includes Archer's Advantage Mode, which factors arrow weight, velocity, and peep height for steep-angle shots.
Can I use this binocular with eyeglasses?
Yes. The BX4-Range HD Gen 2 comes with three interchangeable eyecup sizes. The low eyecups are designed specifically to accommodate glasses wearers while maintaining a full field of view.
Is this binocular built to handle rough field conditions?
Absolutely. It's fully waterproof and fogproof with sealed internals that use advanced internal gases and sealing methods. Leupold designed it to withstand extreme temperatures and elevation changes, keeping moisture out and optics crystal clear for life. The Last Target rangefinding technology also works reliably in adverse weather like rain, snow, and fog.
Can I mount this to a tripod?
Yes. The BX4-Range HD Gen 2 features a built-in 1/4-20 rotatable tripod adapter port, making it easy to stabilize for extended glassing sessions or precise rangefinding.
