Google Earth Pro PC + Garmin GPS = Super GPS
Anyone doing offroad traveling knows a regular gps is almost worthless. The real-time tracking feature of Google Earth is the closest you can get to having your own drone flying above you providing video. It is also extremely buggy unless you do several things to make it happy. Well worth the effort though, wish I had this many years ago. It only cost $100. I go through the whole process in this video.
