Hi - I’m Gregor Heinrich. Welcome to my "Golf & Tesla" channel. If you enjoy the channel, please make sure you hit the “like” button and “subscribe”.
The channel offers informative and entertaining videos on topics such as golf courses, my Tesla car, golf equipment, course VLOGs, occasional equipment reviews etc.
As to "Tesla”: you can also see reports on Supercharger stations I come across.
For both the golf courses as well as the Supercharger reviews I often use a DJI Mavic drone.
So if you are neither a fan of golf nor of Tesla, you can still enjoy the playlist "drone footage" on my channel or better, visit my travel destinations channel @gregorscapades
