This is a SNDWAY rangefinder. I've had it for about 3 years, but I haven't used it much. It works perfectly and is in good condition. Quick Focus System: Easily adjust the focus to clearly capture the target, and rotate the eyepiece to focus on the target. The rangefinder automatically turns off after 8 seconds to conserve battery power. You can turn it back on by simply pressing the power button. * It's the perfect combination of size, speed, and accuracy. Accurate to ±0.5 yards, with a range of 3 to 1000 meters and 6x magnification.
