I am going to venture out tomorrow on a boat and want to get some footage. I want to be as cautious as possible. I know I need to be still to establish GPS lock. I just want to confirm before I run into any issues, if I am on the dock and get home lock, I can keep the phantom on as the boat leave and then take off fine when I am x yards away from the dock, correct? I will later be in waist high water so can get GPS lock by holding it. Does anyone have any other words of wisdom from experience for things I should do/not do? Any advice is appreciated!
