Yes, that is great! Soon they'll carry sonar transducers to send back.
As an engineer, I expect we will soon see either submarine or surface drones with 3D sidescan to locate fish with longer duration. We have all the tech. so it's just waiting for the cost reduction. There's already an ROV that lets you watch on a camera and put your bait in front of the fish.
I wonder if they have regs against drone spearing of fish?
