The laser pointer can not only be a useful device

People who often go camping or hiking may find themselves in trouble or in trouble at any time and need to help solve their problems. However, the essence of the outdoors is that unless they are lucky enough to pass at the right time, it is difficult to ask for help. Using laser pointers, they can attract the attention of people hundreds of meters away, which can help them get rid of their situation. In such cases, they can be an invaluable gadget.
