A very helpful feature in DJI Go 4 is the center point option. It will allow you to select a variety of crosshairs and help you make your flight more precise. I use it for knowing exactly where my drone is going to land. If I gimbal straight down, I can see within inches where my drone is going to set down. While RTH is accurate most of the time, a center point will let you land exactly where you command it to. You can aim for the center of your landing pad, and see it all the way to the ground. Cant get more precise than that, even by eyeballing your drones position.
