Someone falls into the water, how to rescue him quickly? Throw bamboo poles and lifebuoys? Maybe you can also try this.

Every second after falling into the water is crucial, and every second counts for rescue. The previously mentioned life-saving methods are effective in some situations, but if the environment is complex, such as strong winds, fast currents, long distances, obstacles, etc., these methods may not be effective.

However, there is now a new lifebuoy that can solve these problems. It not only has the buoyancy of a lifebuoy, but can also fly on the water like a drone, quickly flying to the side of the drowning person, and easily coping with various complex situations. If you are interested in this flying lifebuoy, you might as well learn about it.
