active tracking

Was on the Exstew River and had my drone follow me down River. Worked great.

asking for some advice please... I want to walk around a lake, on a sparsely tree populated path, and use a mixture of active tracking and tripod mode to take some video of the path and the lake, from each fishing spot. Here's the lake: Could I ask for advice how to approach this project...

when a Spark loses sight of you does it stop and hover or return to home please? thanks for any help.
