Leupold® RX®-1400i TBR®/W Gen 2 5x21mm Digital Rangefinder


SKU: LEU183727 Categories: ,

The RX-1400i TBR/W Gen 2 enters the market as the most versatile, feature-rich rangefinder in its class. Equipped with a bright red display and our high-performance DNA® laser engine, this lightning-fast rangefinder will take your hunting and shooting to the next level.

Its dead-on ranging engine delivers the speed and accuracy serious backcountry sportsmen demand, while its ballistically calculated ranges for riflemen—and Flightpath™ and trig solutions for archers—simplify even the most extreme uphill and downhill shots. Adaptable and powerful, the RX-1400i TBR/W is the perfect addition to any outdoorsman’s pack. It can also calculate 10-MPH windage holds and display additional holdovers in MOA, MIL, inches, and centimeters. Whether you’re carrying a rifle or a bow this season, you’ll want the RX-1400i TBR/W close at hand.


  • Line of Sight (LOS)
    • Line of Sight (LOS) calculates the distance to a target in a straight line, regardless of any incline or decline.
  • Bow Mode
    • Bow mode uses the distance and the angle of a shot to calculate a ballistic equivalent to the target for more accurate uphill and downhill archery shots.
  • Accurate Ballistics Solutions
    • True Ballistic Range/Wind (TBR/W) technology features 25 ballistic groups
      • 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.
  • Last Target Mode
    • Last Target mode ensures the rangefinder reads the farthest target in the laser’s path, so grasses and twigs don’t interfere with an accurate range.
  • Flightpath
    • Flightpath™ technology uses your bow’s ballistics to display the highest point of your arrow’s flight, so you can take tighter shots with more confidence.
    • Don’t know if you have a clear shot? Flightpath technology eliminates doubt by allowing you to see potential arrow obstructions out to a typical distance of 85 yards.
    • Once you finish a quick calibration process, Flightpath will display an illuminated tick mark, indicating exactly where your arrow will be at 20 yards. If you see tree limbs or thick brush above that mark, they’re not a problem, but if they’re at or below it, they could get in the way of your kill shot.
  • Visible Readouts in any Light
    • TOLED displays use bright red numbers and letters and have adjustable brightness settings to optimize readability in changing light conditions.
  • Selectable Reticles
    • Offers a variety of reticles to choose from to fit any use or preference.
  • Find Targets Fast
    • Clear 5x magnification
  • Extreme Climate Tested
    • We make sure our optics perform in the harshest conditions by subjecting them to temperatures ranging form -40 degrees Fahrenheit to 160 degrees Fahrenheit
  • Waterproof
    • Leupold RX rangefinders are weather sealed for guaranteed performance in harsh conditions, from snowstorms to heavy rain
  • Rain + Fog Readouts
    • Last Target mode helps the laser punch through moisture in the air to give you accurate distance readings regardless of the weather
      • Last Target mode ensures the rangefinder reads the farthest target in the laser’s path, so grasses and twigs don’t interfere with an accurate range.

Additional Information:

Whether you’re in a treestand, at the range, or in the backcountry, you’ll never have to second guess the distance of your next shot with an extremely accurate Leupold® RX® rangefinder.

Be More Exact with True Ballistic Range/Wind Technology

Leupold’s True Ballistic Range/Wind (TBR/W) technology takes precision to the next level by offering 25 selectable ballistics groups that account for your preferred cartridge, helping you dial in the exact range of your target.

Using the old rifleman’s rule on an angled 600-yard shot could result in a 10-15-inch margin of error when compared to the dead-on accuracy of Leupold’s TBR/W. And with TBR/W’s 10-mph wind holds, you’ll have all the information you need to experience more first-shot hits.
