What is the best laser pointer in the world?
Scenarios that require directions to neighbors are convenient not only for remote areas but also for directions to neighbors. In the case of neighborhoods, if pointed to by physical means such as a pointer, shadows may appear, making it difficult to see. Meetings, small and precise things Scenarios that require directions to dangerous places Physically pointing at things that are hot or cold, in water, dangerous or harmful in themselves, etc. are dangerous. I was able to get rid of (Eurystomus orientalis, Buddhist monk), which I have not been able to get rid of until now. Crows in the distance are also effective. Bulbul (Bulbul, Baldbird, Hypsipetes amaurotis) also escaped instantly! Very satisfied. A nearby utility pole seems to work well during the day.

Traditional red high power laser pointer
Compared with the traditional red high power laser pointer, the green laser can see clearly in bright and even dark places, and the beam range is farther. The introduction of green laser pointers greatly reduces the production cost of modules. A high-power laser pointer HTPOW popular store is a portable pen type, which is not only the best choice for lighting, but also is used for many business trips in conference presentations, seminars, study groups, etc. . Laser pointers are not toys and can be very dangerous. Regardless, knowing that lasers can permanently damage your eyes, pop balloons, and set fire to tons of different things, we decided to find out how many lasers would be required to be lethal. Best for people. You'll also find some serious challenges facing individuals. The first must be eye trauma. Improper use of infrared laser pointers may cause temporary or even long-term vision damage to human eyes. Laser pointers programmed directly to 5mW power can cause temporary visual impairment. Having said that, extra effective lasers can eventually lead to permanent loss of vision as well as blindness. This difficulty is very serious, especially for underage children. If young people were given the device, they would randomly use a laser pointer to participate with their buddies every day.

Here's a little rant (update) I'm going to add, you can skip it if you want. First of all, some of you are taking the FDA-restricted thing seriously. The FDA states that blue laser pointer damage can come from beams >5mW, the lowest power they can think of. They did scientific testing to find the absolute lowest power that could damage your eyes, and every possible worse case (basically point blank range, low divergence, most sensitive part of the eye, etc.).
