Being super accurate and convenient, the UZI Laser Rangefinder Plus will change the way you hunt or shoot forever! It features a fog filter, flagpole scan and speed measurement. These extra features allow you to scan a specific item and lock in on it to the exclusion of anything around it, measure the speed of a moving object and prevent errors caused by fog. The rangefinder has a range of up to 600 yards with a +/- 1 yard accuracy. It has a 21 mm objective lens with 6X magnification and a tough, water-resistant housing. The compact, lightweight 5 oz. design uses one CR2 battery (not included). A carry pouch, neck strap and lens cloth are included.
