CUSTOMIZE TO YOUR ARCHERY SETUP
Archer's Advantage calculates ballistic angle-compensated ranges for your specific archery setup.

TRUE DISTANCES AT STEEP ANGLES
TBR/W provides ballistically calculated solutions for rifle hunters at longer distances and steeper angles.

ELITE OPTICAL SYSTEM

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.

ADAPTABLE TO YOUR NEEDS

INTERCHANGEABLE FORM-FIT EYECUPS
Three different options provide a customized fit that reduces eyestrain to extend your field time.

MULTIPLE MAGNIFICATIONS
Available in 10x42 for a wider field of view or 12x50 for long-range observation.

PROGRAMMABLE POWER BUTTON
Switch your power and mode buttons to allow for left-handed or right-handed operation.

The BX-4 Range HD Gen 2 TBR®/W 12x50 fuses our DNA® engine and ballistics software with the optical performance diehard hunters and shooters demand. Now you can spot and range targets without switching optics. It has a maximum range of 4,000 yards on reflective targets and 2,200 yards on trees. Its high-contrast red OLED display delivers crisp readouts in any light, while edge-to-edge HD clarity reduces eye strain for longer glassing sessions. 

Features
Leupold’s Elite Optical System 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.
True Ballistic Range® / Wind (TBR®/W) technology provides ballistically calculated ranges for extremely accurate shots at longer distances and steeper angles. It can also generate a hold point for a 10-mph wind at a 90-degree angle out to 800 yards.
With its TRIG function, Bow Mode is an excellent “set it and forget it” feature that is simple to use and accurate out to around 70 yards and for angles less than 20 degrees. This function is ideal for Western spot-and-stalk hunters and tree-stand hunters, providing 10-ring target level accuracy.
Last Target guarantees that the rangefinder identifies the most distant target along the laser's trajectory, preventing inaccuracies caused by adverse weather conditions like rain, snow, or fog.
Line of Sight (LOS) calculates the distance to a target in a straight line, regardless of any incline or decline.
Our Form-Fit eyecups come in three different sizes, allowing you to customize your viewing experience based on your preferences. Choose the winged eyecups for blocking out stray light, opt for the medium eyecups for all-around comfort, or select the low eyecups designed specifically for use with glasses.
Archer's Advantage mode uses your arrow weight, arrow velocity, and peep height to deliver precise range calculations made for shooting at steep angles or over long distances.
Our ergonomic design ensures our products are slim, lightweight, and fit well in your hands no matter what size they are.
Easily locate the buttons with easy-grip standoffs, even through thick gloves. Prevents accidental activation and battery depletion.
A built-in 1/4-20 rotatable tripod adapter port makes it easy to mount to a tripod.
Features an extremely smooth focusing system for fine adjustments.
Leupold pioneered modern waterproof and fogproof technology using advanced internal gasses and sealing methods that withstand extreme temperatures and elevation changes, so the internals of the optics stay moisture free and crystal clear for life.
