I found the 'Home Lock' feature really useful the first time I made a big 'away' flight. Home Lock makes it possible for you to use the right-hand stick in a mode where you push it forward and the drone goes away from you, and pull it back and the drone comes back to you - no matter what way the Mavic is pointing! This allows you to to do all the up & down and yaw that you want to do, but takes out that need to get the drone pointed exactly back at you to bring it home. That first time you let your Mavic go to 120 metres and half a km away, can be pretty nerve wracking - but once done, you'll be doing it all the time!
What is 'Home Lock' I can't find any mention of it in the User Guide?
