Man Jumps Into Lake To Save Dying Drone Before It Lands In Water

posted by @BrianFink - 

This guy jumped into a lake and swam out to save his drone.  And just in time; he got to it right before it hit the water. The drone's battery had died.

I don't know a lot about drones, but shouldn't it be waterproof? And have a back up battery? Did he really need to rush out there like that?  Maybe he was worried about it floating away afterwards. 

If you know a lot about drones, help me understand this...
