The DJI Mavic is a wonderful drone for aerial video. With DJI Goggles and other accessories, you can get even more out of it. The PolarPro Katana allows you to use your drone to capture video in no-fly zones. It also comes with a smartphone mount to let you frame your subject better.
Katana relies on your Mavic’s camera and gimbal to let you shoot smooth video. The kit comes with tray, harness, and phone mount. More info is available here.
