HOVER ARK H3
This is a remote-controlled lifesaving buoy that can rush to rescue at 4m/s to save the drowned. Rescuers no longer need to risk their own lives. Just stand on the shore or a boat and use the remote control for the whole operation.
This fast moving watercraft is designed specially for first responders for emergency situations on the water. You can move it around with a car, carry to the shore by a single lifeguard and save lives in seconds.
