The life preserver idea of the Splash Drone 3 is a commendable one. Who would have thought that drones can be used to save lives, unlike to what most people would normally do to a drone- to take aerial videos and pictures or to have a race against other UAV's. That is why they say, a drone is a big man's toy. But Splash Drone 3 stands out because of it's being 100% waterproof and it's payload release system which can carry a lifesaver such as Personal Flotation Device (PFD) and bring it to someone who would need immediate help in cases of drowning or being stranded to somewhere like what this demo in this video.
