8x optical lens, high transmission prism, IP54 safety protection, lock target, one-key measurement. It is suitable for many occasions, such as mountaineering off-road, golf course, electric power survey, building construction survey, etc. Measurement mode ranging, scanning, angle measurement, height measurement, speed measurement, golf mode.Instructions: Single measurement: press the launch key once, the instrument displays the distance measured this time; Continuous measurement: long press the launch button to scan, the instrument will display the current measurement distance in real time;Distance test mode: During distance measurement, due to the influence of angle (A or -A), the measured value is the distance from A to B or C. Always press the power button without letting go, then press the mode button, and then release the Open two buttons to enter scan mode;Test mode: The distance difference between the two distances of the moving object divided by the time interval between the two sides is the speed of the object moving.Product name: TesterRanging range: 5-600mMagnification: 8XRanging accuracy: +/- 1M (Y) +/- 0.1%Exit pupil diameter: 4.1Measuring height and angle: +/- 90Angle measurement accuracy: +/- 0.5Objective lens diameter: 25mmLasering type: 905 nm, semiconductor laseringInstrument size: 117x42x79mmWorking temperature: -20~50Focus Mode: Manual FocusTripod mount: yesBattery Type: CR2 3v (without battery)Scanning function: yesAuto-off time: 20SColour: WhiteMaterial: ABSPackage Contents:1 * Rangefinder1 * English manualOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
