Factors affecting the distance measurement and accuracy

Laser reflection: The rangefinder measures the distance based on the time it takes the laser beam to travel to the target and back. The larger the target or lighter the surface the more accurate the measurement will be.

Influence of glare: The rangefinder applies 905nm laser, which is the same as the sunlight 905 band wavelength. If the sunlight is very bright and glaring, it can interfere with the light returning and reduce the measurement distance.

Rain and fog: Adverse weather such as rain and fog may affect the laser ray path. This could lead to a measurement error.
