Overview
The Leupold RX-1400i TBR/W Gen 2 is a laser rangefinder for hunting and archery, ranging up to 1,400 yards on reflective targets and 1,200 yards on trees, with ballistic-compensated readings and a switchable bow mode.
TBR/W stands for True Ballistic Range/Wind, meaning the unit does more than measure straight-line distance: it factors in shot angle and can output a wind hold at 10 mph out to 800 yards. The added Flightpath bow mode is meant for archers checking for obstructions along an arrow's path, on top of the rifle-focused ballistic calculations.
- Ranges to 1,400 yards on reflective objects, 1,200 on trees
- True Ballistic Range/Wind (TBR/W) calculation
- Wind hold output at 10 mph out to 800 yards
- Selectable Bow mode with Flightpath technology
Who it's for
Fits hunters and shooters who need angle-compensated range and wind data at longer distances, and archers who want the bow-specific Flightpath mode. Overkill for someone who just needs a basic yardage number at short range.
What buyers say
From Amazon customer reviews.
Reviewers repeatedly credited the Leupold name for build quality and called the readings accurate and easy to use in the field, including a first-time buyer using it on a hunt. The only variance noted was a single reviewer's reading running about 2 yards off from a separate rangefinder.
Strengths and trade-offs
Drawn from this product's published specifications.
- Accurate readings reported across multiple reviewers
- Bright, adjustable red display readable in low light
- Ballistic-compensated range for angled shots
- Selectable bow mode with Flightpath obstruction detection
- Small variance noted against a second rangefinder
Performance notes
The red TOLED display adjusts brightness for low light and stays legible against the field of view, and reviewers describe readings as consistent and fast to acquire. One reviewer measured a reading 2 yards off compared to another rangefinder, which falls within the kind of variance expected between two different units at range.
