Nikon’s Laser 30 Laser Rangefinder provides precise measurements up to 1600 yards away in an ergonomic, handheld package. It comes equipped with First Target Priority Mode and Distant Target Priority Mode. Frist Target Priority delivers the exact distance to the closest object in a group of targets. This allows accurate range finding for smaller objects. Distant Target Priority gauges the range of the farthest target among a group of objects, a useful feature for finding the distance of a target behind tall grass or brush. In addition, the Laser 30 features Nikons own ID (incline/decline) technology, this advanced software provides the horizontal distance to the target even when gauging the distance at various incline/ decline angles, up to an incredible +/- 89 degrees.
