Never shine a laser pointer toward any person, aircraft, or other vehicle. Never look directly into the beam of a laser pointer of any type. Do not allow children to use a pointer unsupervised. Laser pointers are not toys. If your telescope is equipped with a laser pointer that has a “constant-on” setting, do not leave the instrument unattended with the laser switched on. Do not aim a laser pointer toward mirrors or other shiny surfaces. The reflected beam may inadvertently strike someone in the eye. Do not aim a laser pointer in the direction of anyone using a telescope or binoculars for either astronomical or terrestrial viewing. Do not aim a laser pointer skyward if you hear or see an aircraft of any kind flying overhead. Do not use a laser pointer within 3 kilometres (2 miles) of an airport. The use of laser pointers is prohibited at some star parties and other astronomy gatherings. Always comply with such restrictions. Be aware of irresponsible uses of pointers so that the psychological effect will be minimized if you happen to be illuminated by one. Do not purchase a laser pointer if it does not have a “caution” or “danger” sticker on it identifying its class. In the box Box | Laser Pointer Pen | Rechargeable 18650 Battery | Battery Charger
