#SundayGunday: Leupold BX-4 Range HD TBR/W 10X42mm

posted on June 9, 2024

This week on #SundayGunday, we’re taking a look at the BX-4 Range HD binos, from Leupold. Merging the True Ballistic Range accuracy of Leupold’s rangefinding technology with the company’s BX-4 High Definition binocular, the BX-4 Range HD provides shooters with the clarity to spot distant game, and the ability to range it in an instant when seconds count. Utilizing a DNA engine and ballistic software, the binoculars can return ranges out to 2600 yards on reflective targets, and was able to accurately range natural targets out to 1400 yards during our testing, to within a yard of our control unit. A high-contrast red OLED display has three brightness settings for use in the brightest daylight all the way to last light. It's obvious when a bright format is important, but the dimmer options are crucial as well, to avoid washing out the entire image in the evening.

Heads up display aside, the BX-4 Range HD boasts 10X magnification, widely considered optimal in balancing magnification with a wide field of view. On this model, it is 334 feet at 1000 yards. Forty-two millimeter objective lenses further complement this balance, providing a compact package while still allowing in plenty of lumens for those last-light scenarios. To the rear, oversized eyepieces and adjustable eye-relief cups make the binocular easy and comfortable to use. The eye relief cups can also be replaced or removed in the field if damaged. On the bridge of the binocular, a smooth focus wheel works in tandem with adjustable diopters for both eyes, to provide optimal clarity.

Herman Using BX-4 Range HD TBR W

Within, the TBR/W—aka, true ballistic range and windage—system can instantly calculate for shots at long distances and extreme angles, displaying the adjusted range to the user. It will also generate holds for a full-value 10-mph wind out to 800 yards. Bow mode utilizes the same engine, displaying the line of sight measurement with the button held, and recalculating to the proper yardage that should be aimed for when released. A standard, line of sight measurement is also included.

Despite their high-tech nature, the glasses are fully waterproof and fogproof. Their 39-ounce weight is light enough to glass without the need for a tripod, though they do include a 1/4-20 TPI tripod adapter should you want one, and the glass is shockingly clear for a rangefinding unit. For more information on this excellent rangefinding binocular, which utilizes a CR2 battery for up to 3000 ranges and retails for $1,599.99, visit leupold.com.
