The 120XL laser rangefinders measure up to 120 yards, making them the perfect rangefinders for bow hunters, small game hunters and golf course professionals looking for a low cost amenity. The XL Series rangefinders also come in 400-yard, 600-yard, and 800-yard models. All models have an accuracy of +/- 1 yard and operate on a single 9-volt battery. The 400XL and 600XL models are user programmable for measurement in feet, yards or meters. The 120XL can be factory calibrated for feet, yards or meters. The XL units can be set to audible "chirp" mode or silent "stealth" mode to suit the application and can be used at an industry leading four-yard minimum.
