Leica upgraded the Rangemaster 1600 with the ABC ballistic program to dial you in for dead-on accuracy. Never before has a rangefinder been capable of such precision. In the calculation of the ballistic curve, this innovative feature integrates data for the angle of declination, temperature and barometric pressure particularly useful on mountainous terrain. By also precisely integrating ammunition parameters, it delivers accurate sighting point corrections taking the guesswork out of rangefinding. High-performance optics deliver clear sighting of game, even at longer distances. The wide field of view ensures fast target identification. AquaDura hydrophobic coating on lenses repels water. Ranges out to 1,600 yards. Includes carrying cord, battery and Cordura nylon case. Dimensions: 2-1/4"H x 4-1/2"W x 1-1/4"D.
