Maximal rangefinder range

Is the maximum distance to which the laser rangefinding device correctly performs the measurement and determines the distance to the observed object. What is also good to know is that the given maximum rangefinding distance is only at perfect environmental conditions. This means, the rangefinder with a maximum rangefinding distance till 1000 meters will measure this distance only in cloudy weather, or when the sun goes down. Ina bright sunny or rainy days the maximum rangefinding distance shortens.
