Archers beware doesnt read dark targets (black or dark brown) 3d targets - Nikon ACULON Laser Rangefinder - 6x20mm

Great price nice size unit !! 3D archery black pig target was 30 yards and range finder read 61.Its stated on page 8 of owners manual that product may be inaccurate on "Black Target" My opinion Nikon should state this on product specs.3D archers shoot black targets.Hunters shoot black animals.I'm going to contact Nikon but I dont think its going to do any good far as return or upgrade to a range finder that reads black targets.Probably for golf or open well lit fields ranger finder will work fine.
