Leupold BX-4 Range HD Gen 2 TBR/W 10x42 Rangefinder Binoculars
The Leupold BX-4 Range HD Gen 2 TBR/W 10x42 is built for hunters and shooters who want to glass, range and make confident distance calls without swapping between binoculars and a separate rangefinder. It combines Leupold’s HD optical performance, a powerful laser rangefinder, red OLED display, Bow Mode, Archer’s Advantage and True Ballistic Range/Wind technology in one rugged field-ready optic.
Glass and Range in One Motion
When seconds matter, the BX-4 Range HD Gen 2 lets you stay behind the glass and range directly through the binocular. The 10x42 configuration gives a strong balance of magnification, field of view and low-light usability, making it ideal for stalking, open-country hunting, ridge glassing and general long-distance observation.
Its high-contrast red OLED display is designed to stay readable in changing light, while the HD optical system helps maintain clarity and contrast during long glassing sessions.
Key Features
Elite Optical System
Built for bright, sharp and high-contrast viewing, with edge-to-edge clarity that helps reduce eye strain during extended observation.
Built-In Rangefinder
Range directly through the binocular with maximum capability up to 4,000 yards on reflective targets, 2,000 yards on trees and 1,300 yards on deer-sized targets.
TBR/W Ballistics
True Ballistic Range/Wind technology provides ballistically calculated solutions for rifle hunters, including support for steep-angle shooting scenarios.
Bow Mode
Designed for archery use, Bow Mode uses angle compensation to help provide practical equivalent distances for uphill and downhill shots.
Archer’s Advantage
Archer’s Advantage allows setup around bow-specific information such as arrow weight, arrow velocity and peep height for more tailored archery range calculations.
Waterproof and Fogproof
Built for demanding field conditions, with sealing and internal protection designed to keep the optic clear through wet, cold and changing environments.
Built for Hunters Who Move Fast
The BX-4 Range HD Gen 2 is designed to cut down on gear changes in the field. Instead of locating game with binoculars, lowering them, grabbing a rangefinder and trying to reacquire the target, this unit lets you identify and range with the same optic.
- 10x magnification gives useful reach while maintaining a practical field of view.
- 42 mm objective lenses balance brightness, portability and all-day carry comfort.
- Red OLED display provides crisp, high-contrast readouts.
- Programmable power button allows left- or right-handed operation.
- Interchangeable Form-Fit eyecups help customise comfort and block stray light.
- 1/4-20 tripod compatibility supports steadier long-distance glassing.
- CR2 battery power with up to 3,000 actuations.
Ranging and Ballistic Modes
The BX-4 Range HD Gen 2 TBR/W is more than a simple line-of-sight rangefinder. Its ballistic modes are designed to support both rifle and archery use, making it a flexible choice for hunters who move between different seasons and setups.
| Mode / Function | What It Does |
|---|---|
| TBR/W | Provides ballistically calculated ranges for rifle use, including steep-angle shooting scenarios and wind-hold information. |
| Bow Mode | Designed for archery, giving angle-compensated distance information for more practical uphill and downhill shot decisions. |
| Archer’s Advantage | Allows bow-specific setup using information such as arrow weight, arrow velocity and peep height. |
| LOS Mode | Provides straight-line distance to the target without incline or decline compensation. |
| Last Target | Helps prioritise the farthest target along the laser path, useful when ranging through rain, snow, fog or foreground clutter. |

Why Choose the BX-4 Range HD Gen 2 10x42?
Choose the 10x42 model if you want a practical field binocular that still gives serious ranging capability. It offers a wider, more manageable view than higher-magnification rangefinding binoculars, while still giving enough reach for confident identification and distance readings across hillsides, bush edges, paddocks and open country.
For hunters who want fewer tools, less movement and faster target confirmation, the BX-4 Range HD Gen 2 TBR/W is a smart all-in-one solution: quality glass, accurate ranging and useful ballistic data in one compact optic.
