Chinese company Didiok Makings has come up with a flying lifebuoy, which is useful in cases where rescuers can not throw ordinary or quickly get to the drowning.

The device is essentially a controlled drone. Thanks to the IP68 moisture protection, it can land and hold on to water, and is not afraid to dive to a depth of one meter for half an hour.

As the developers say, such a hybrid copter and lifebuoy is able to keep two adults. In the air, it reaches a speed of 47 km/h, and before landing on the water, it turns off the engines to avoid hurting the drowning.

In China, the device is offered at a price of about $11 800
