 Instructions:
A laser pointer is a small laser designed to highlight something of interest by projecting a small bright spot of colored light onto it. The laser beam is not in itself visible from the side, but is visible as a result of light scattered by dust particles along the beam path. The small width of the beam and low power of typical laser pointers make the beam itself invisible in a reasonably clean atmosphere, showing a point of light when striking an opaque surface. Some higher powered laser pointers are faintly visible via Rayleigh scattering when viewed from the side in moderately or dimly lit conditions.

This laser can measure you the accurate position of the building in the faraway distance by avoiding going close to the dangerous field.
NOTE:
- The laser can be bright enough when you light it in normal temperature, so you had better not light it continually over 30 seconds
- When not using it, please take off the battery from the laser to avoid damage
- In some countries these laser pointers (especially the higher powered ones) may be illegal to own and/or use. Therefore, YOU (the customer) must accept all responsibly and liability to determine and fulfill the requirements and limitations of use or resale of these products in accordance with your country's laws and regulations. In the event of resale, you also need to agree to incorporate this notation in the product description, so that any potential buyer can be well informed before making an purchasing decision
Safety Considerations:
Laser pointers are effective tools when used properly. The following considerations should be observed when using laser pointers:
- Never look directly into the laser beam
- Never point a laser beam at a person
- Do not aim the laser at reflective surfaces
- Never view a laser pointer using an optical instrument, such as binocular or a microscope
- Do not allow children to use laser pointers unless under the supervision of an adult
Use only laser pointers meeting the following criteria:
- Labeled with FDA certification stating "DANGER: Laser Radiation" for Class 3R lasers or "CAUTION: Laser Radiation" for Class 2 pointers
- Classified as Class 2 or 3R according to the label. Do not use Class 3b or 4 products
- Operate at a wavelength between 630nm and 680nm
- Have a maximum output less than 5mW, the lower the better
Package Included:
- 1 x Flashlight Handheld Pure Red Laser Pointer Pen
