The Bushnell Bone Collector 850 Laser Rangefinder is designed with a 50-percent-larger fully multi-coated objective lens to effectively draw in more light to the eye for a brighter image, making this rangefinder an essential tool for hunts at dawn and dusk. The sharp display delivers exceptional light transmission to optimize performance in all environments, and the all-glass optical system features ultra-wide band coatings that provide vivid, true-to-life colors, so you can clearly see your target. This rangefinder with ARC technology is specially designed to account for angled terrain, giving you the true distance to your target regardless of whether you are above or below it. Scan mode updates ranges four times per second, delivering instant, real-time feedback on your shot. This 6x24mm laser rangefinder measures distances up to 850 yards reflective, 500 yards to tree, and 350 yards to deer. One button design makes it easy to operate the unit and quickly range a target. The vivid display reticle offers easy-to-read distances in yards, meters, or feet as well as the incline angle and remaining battery life. A fast-focus eyepiece lets you quickly adjust the reticle to your eye, so you can focus in on your target with perfect clarity.
