A BT external GPS works just as well on a Wifi only iPad. That's what the real pilots use in their airplanes, instead of a cellular iPad. Far more accurate and reliable, and won't burn up your iPad battery, like using internal GPS in a cellular iPad will.It's a convenience mostly. You can easily have the maps download to the Go4 app and see where the drone is on the map, in relation to the launch point, if you're connected. Without cellular service in the iPad/Tablet, you'll have to use your phone as a hotspot to download your maps in the field, which is just a little different is all. You can also pre-download maps at home before you fly, if you know where you're going to fly, but I find this restricting because I'll often fly spontaneously when I see something as I'm driving along. I'll just pull off the road and fly at a moments notice if I see something interesting.
Also important to know, that with iPad's, when connect to a hotspot, like your phone, you CANNOT reset your homepoint, during flights, if you move the RC location, like in a boat (RTH needs this) You must have an iPad with Cellular to have GPS location services, in order to reset the launch HOME POINT in the GO4 app. Most Android tablets that are non-cellular have GPS for location services, allowing HOME POINT RESET, so that's not an issue with Android.
