It does have a RTH (return to home function) . It's important that you sent the home point from exactly where you take off. Also you need to set the RTH altitude to a height that will clear anything on the way back. So best to set it high.....
Set your low batter warning for no less than 25% so it has lots of time to get back.
If it's possible... best to do this with two people... one as the operator with eyes always on the control display and the other right next to you as a spotter with eyes in the sky on the drone at all times.... Keep constant verbal communication. This way you can focus on getting images without constantly looking up to find your drone in the air to see if it's safe. You'll burn through a lot of battery just doing that.
You should do your best to never let it get out of sight of you or better, your observer.
Don't launch unless the batteries are 100%.
When you get to a point of interest. take your pic or if video... start rolling and wait a solid 10 seconds before you stop rolling and move to a new location
Once you're comfortable, switch to S (sport mode) to get to where you need to be quickly, then to normal or tripod mode to get your images.
Take off from a large flat area... this way if you do need to return to home, you have some wiggle room.
I know... I have some time on drones.
