Precautions
As the handheld laser rangefinder uses lasers for distance measurement, and the pulsed laser beam is a monochromatic light source with very concentrated energy, do not look directly at the launch port with your eyes when using it, and do not observe the smooth reflective surface with an aiming telescope. , so as not to hurt people's eyes.
Be sure to measure according to the safe operation specification in the instrument manual.
