Fishing with a Phantom - Fisherman flying out their fishing line with a Phantom

Amazing what some fishermen in Taiwan do with their DJI Phantom.
They hooking up the fishing line to the Phantom and fly several hundred meters out to the sea. Then they unhook the line and let the Phantom automatically flying back while they concentrated on the fishing.

 

I just wanna know what model they used for taking that video so stable and nice

 

I just use a DJI Phantom 2 Vison +

 

Oh, that's nice. I supposed it's a hexacopter so stable.

 

Very interesting.
