Why is laser effective to catch crows?
Crow-killing measures: In recent years, mysterious weapons have appeared on the market. Scientists have invented a weapon that can drive away birds. This is a super powerful green laser pointer crow insect repellent. Use the principle of rays to drive away crows. The wavelength of the light emitted by the green pen laser pointer is 532nm, which belongs to Class IIIB. Use section 2 of AAA battery. The light of the green laser is slightly stronger, which is more harmful to the eyes, and the higher the output, the greater the harm. Usually, 5mw is often used. In the US market, a 5mw laser pointer is acceptable, but if it exceeds 5mw, it cannot be used without approval. At home, it is not so strict. Therefore, special care must be taken during use. Do not irradiate eyes and fragile parts! It is also important to be careful that the laser light enters your eyes due to reflections. Laser pointers that can adjust the focus of the green light usually also have a protection switch.

This laser pointer is not only red, but also green. Not only for cats, we also recommend leather pointers for conferences, expeditions, exhibitions, tourism leaders and many other places, as shown in the picture below. A wide range of! If you want an instant repelling effect, you should use a green laser of 3000mw-10000mw and a blue laser pointer of 1000mw or more. The 10,000 mW blue laser pointer and 10,000 mW high power laser pointer are sacred treasures that are instantly repelled. (Note: drive away crows, not kill them) For red lasers, it is best to have 3000mw or more. (Red laser is not as effective as green laser and blue laser, so we recommend high-power green and blue light)
