The Leupold(R) RX-1200i TBR/W with DNA(R) Digital Laser Rangefinder takes the guesswork out of allowing for wind drift, without having to use wind gauges or other devices. Just select your ballistic group and true ballistic range/wind automatically calculates wind hold values, designed to work with Leupold's ballistic reticles. The RX-1200i also features TBR (True Ballistic Range(R)) technology, with 4 ballistic range readouts, that matches your rifle's ballistics with hold over or turret adjustments. Digitally eNhanced Accuracy? (DNA) reaches out to 1200 yards to process and display distances with incredible speed and accuracy to the nearest 1/10th yard. Measurements are easily seen on this Leupold rangefinder on the OLED (Organic Light Emitting Diode) display, without interfering with the image. Fully multicoated lenses provide clear, vivid contrast for seeing game against natural backgrounds. The 6x magnification with clicking fast-focus enables hunters to acquire targets quickly. Scan mode gives continuous updates on distance as user sweeps across varied terrain. A Quick-Set Menu(R) and 1-handed controls make the RX-1200i TBR/W simple to use, with a choice of 3 reticles. Fold-down rubber eyecups accommodate users with eyeglasses, and a fast-focus eyepiece brings in targets sharply. The Leupold RX-1200i TBR/W with DNA Digital Laser Rangefinder operates on 1 CR2 Lithium battery (included)
