It is not viable for cave exploration, much less body recovery.
Salt water already makes communication hard enough at that depth I think, the rock layers make it harder. The subs also cannot get everywhere a person can. A person can drag themselves through tight holes if needed, the drone cannot. Finally, body retrieval. The bodies are bloated and decomposing in salt water. How would you attach the drone to them, much less get the bodies out of the cave without risking rubbing them on the harsh and shredding rocks of the cave? The way divers do it, is by putting them in a body bag before taking them out.
There are autonomous miniature subs. Why not send them in?
