Note:​​ The nominal range and accuracy are achieved under the environment of visibility not less than 10 km and relative humidity not greater than 60%. The ranging capability and accuracy of the rangefinder may vary under different environments and with different targets. Please refer to the actual measurement results. If the rangefinder is used on a stabilized platform, ensure that the platform can track the target steadily; otherwise, the ranging range or accuracy of the rangefinder may be affected.
