What are the advantages of the laser pointer around
The laser pointer is easy to understand the instructions even in dark places. In the case of pointers, the physical length is the instruction range. Even if the range of the instructor is taken into account, the instruction can only be about 2m at most. Further, according to this principle, the longer the pointer, the heavier the hand, which is more painful for the operator. In addition, the long stick will be obstructed when it is not in use. However, when a blue laser pointer is recommended, even a product that can be pointed at a distance of 300m is relatively short, and holding it will hardly feel tired.
