Nikon Laser 30 RangefinderThe Nikon Laser 30 Rangefinder is a multipurpose device that measures horizontal distance, actual distance, and angle up to 1600 yards, in 0. 1 yard increments. This makes it ideal for forestry, construction, or any outdoor activity. Distance readings are displayed in ~0. 3 seconds, and Nikon's Tru Target technology allows you to switch between First Target (object in front of background) or Distant Target (object behind obstructions such as trees).
