Search & Recovery - Drone Lost

Small group for divers called to work as a team finding a valuable Camera Drone that was recording a Nation Canoe race with live television streaming.
Diving in 10 degrees, low visibility and in a fresh water area where i have caught huge fish .. haha.. Now i know it looks like down here in Rodeplaat Dam.
My role in the team was to hold a solid anker, and release the line to the other teammates, controlling their movements outwards, and on return.
