The latest long-range rifles and ammunition go farther than ever. The RX-2800 TBR/W goes way, way out there, too. Powered by Alpha IQ, it ranges farther, faster, and more accurately than any other monocular you can carry. At 7x, it�s also the most powerful Leupold monocular, with the optical performance you need to pick out distant game. TBR/W technology takes into account the angle of your shot and your rifles ballistics to put you dead on. Line-of-sight measurements wont put you on target and any other rangefinder wont give you accurate ranges because they use basic trigonometry to calculate the distances instead of true ballistics. TBR/W is also the easiest way to account for wind out to distances of 800 yards. It generates hold point for 10-mph wind at 90 degree angle to your direction of aim.
