The 120XLA & 120XTA are short range Laser Rangefinders loaded with the technology, adapted for the archer. High precision and improved accuracy are just two of the advantages of these Laser Rangefinders. Readings are taken in half yard increments, thus improving your accuracy. Narrower infrared beam gets you "through the brush readings" better than ever before. A narrower beam coupled with a superior detector also means acquiring smaller targets at greater distances.
