The device is a high-thech portable machine, which combines the functions of telescope and laser range fingers, it changes the distance measuring distances and also improves efficiency.The device can measure the distance and speed while using the bright images, and have some advances, such as high precision, short divergence time, visual display, low consumption and automatic power-off.The device is safe for the eyes and body using 905 nm and multi-coating lens, and it can be used on different fields such as the electricity, the safe guard, the Golfand the forest.Before surgery, rotate the body until the images through the two eyepieces aimed at one object, then adjust the eyepieces, the images are then Transparent.Remove the glasses to fit the glasses or adjust the cups of the eyepiece.Magnification: 6x lens: 24 mm maximum distance: 600m -1500mMinimum distance range: 5m Uy5 yard accuracy: +-1m field angle: 7 speed range: 300 km H HWavelength: 905 nm Power Supply: CR2 3.0V Battery Item Size: 123,77,43 mm Item Weight: 168G PackageSize: 118x81x41mmPackage weight: 210 gPackage list: 1.RangeFinder 1CarryCase 1Cleaning Cloth 1User Manual (English) 1Battery CR2 3.0V
