Test in 3 different environments of the video transmission between the Mavic Mini and the display device connected to the remote controller. The 3 environments include a flight over the ocean, a suburban area, and in a city. See how the video feed is affected as a result of signal interference, and better understand what to expect when video feed becomes glitchy, lags, and even goes blank. Also, see some basic actions to take (or not to take) when the video feed becomes poor.
Quick Note: I'm actually impressed by the range capabilities of the Mavic Mini, especially for it's size and flight capabilities, and do enjoy flying this drone, however, it's important to be aware of the limitations, which this video sheds some light on.
