What the RX-1400i TBR/W Gen 2 is
The RX-1400i TBR/W Gen 2, part 183727, is a Leupold hunting rangefinder: a 5x, 21 millimetre monocular with a laser, an inclinometer and a red TOLED display with adjustable brightness. Leupold's page and the manual both give 5.1 ounces. The page lists 4 by 1.4 by 3 inches, and the manual 3.9 by 3 by 1.4 inches.
It is built around three ranging outputs, which the manual lists as TBR, BOW and LOS. Line of sight gives the straight distance. TBR, or True Ballistic Range, gives rifle shooters a range matched to a ballistics group. Bow mode gives archers an angle-compensated range, with Leupold's Flightpath feature added.
The Amazon listing's variant line matches: Model 183727, RX-1400i TBR/W Gen 2 with Flightpath. Its colour field says red while the title says black and gray; the two listing fields disagree, so check the listing photos before ordering.
Range and accuracy by target
Leupold's manual gives typical maximum ranges of 1,400 yards to a reflective target, 1,200 yards to trees and 900 yards to deer, and the product page table repeats those figures. The manual says target reflectivity, plus haze, fog, rain and sun, all affect how far it will range.
The manual states accuracy as plus or minus half a yard or metre under 125 yards and plus or minus two yards beyond that. The product page table lists 0.5 yards to 125, 2 yards to 1,000 and 0.5 percent above 1,000 yards, which adds a figure the manual does not give.
Minimum range also differs slightly within Leupold's own material. The manual's introduction says 5 yards, while its hints section and the product page say 6 yards.
Rifle use: TBR, holdovers and the 10 mph wind value
The manual says TBR is matched to twenty-five firearm ballistics groups, and it includes load tables for choosing the group that fits your cartridge; those table pages were not part of what we read. Pick your group before relying on the TBR output.
Settings let you show that result as a shoot-to distance or as holdover in MOA, mils, inches or centimetres, according to both the product page and the manual. The wind function gives a fixed hold for a 10 mph full-value crosswind; Leupold's features list says out to 800 yards, and the manual explains how to scale that hold for other speeds and angles.
Leupold's product page specification table includes a line reading True Ballistic Range (TBR) Mode: No, while the same page, the manual and the model name all describe TBR/W.
Archery: bow mode and Flightpath
Leupold says bow mode, with its TRIG function, is accurate out to around 70 yards and at angles under 20 degrees. The manual lists BOW as one of the unit's three outputs, alongside TBR and line of sight, and the listing describes Bow mode with Flightpath.
Flightpath shows an illuminated tick mark at 20 yards to help you judge arrow obstructions, according to Leupold. Leupold's page says it works out to a typical 85 yards, while the manual says output is typical to about 70 yards. The two Leupold documents give different figures.
Flightpath only works once calibrated to your bow. The manual refers you to a separate calibration sheet, downloadable from Leupold, and notes that below 20 yards, or when the arrow's path exceeds the top mark, the marks blink.
Controls, battery and weather
Settings are made through Leupold's Quick Set Menu, which the manual says opens when you hold MODE for one second. The unit powers off after 30 seconds idle and saves your choices, and the manual describes a factory reset for returning to the original settings.
Last Target mode shows the farthest object, which Leupold's page presents as a setting for rain or fog. Scan mode updates the distance continuously while you hold the power button. Power is a CR2 battery; Leupold lists more than 3,000 actuations per battery.
Leupold's page describes RX rangefinders as weather sealed, and the manual calls the unit waterproof. The Amazon listing gives IP54 and a water resistance field of Water Resistant; Leupold's pages we read do not state an IP rating. A lanyard and attachment are included according to the manual.
Warranty and who this suits
The manual's warranty section says the Leupold Electronics Warranty covers the electronic components of RX rangefinders for five years from the date of purchase, and its specification table also says five years. It points to leupold.com/warranty for full details.
The Amazon warranty field instead quotes Leupold's lifetime guarantee for riflescopes, mounts, red dots, binoculars and spotting scopes, then refers to separate electronic warranties. That lifetime wording does not name rangefinders, while the manual gives five years for the electronic components of RX rangefinders.
This suits a hunter who shoots both rifle and bow, will set up a ballistics group and calibrate Flightpath, and wants hold values in the display. It suits you less if you only need line-of-sight distances, want an app connection, which Leupold's table lists as not supported, or want an IP rating stated by Leupold itself.
