I bought a Mavic Pro and am still a beginner. I used it to inspect my rig, and my roof at home, and it’s truly an amazing piece of technology.
I look forward to more pictures of my boat under sail, new perspectives on sunrise and sunset, etc.
As for privacy, I try to be careful not to fly low or close to private property or people outside my own. I respect FAA guidelines and asked permission before flying low above my boatyard. I think drone operators need to be extra careful because there are “paranoid” people who are irrationally sensitive and and might make unjustified accusations.
FYI, there’s an app called Verifly that lets you buy Drone operation liability insurance by the flight.
