I've searched everyway I can think of and could not find what I was looking for. So here I am, is there anyway to assign a Lat Long Position such that my Mavic Air 2 can go to that point?

Bascially, I am trying to find a property line marker in dense brush and would like a general idea of where it is before cleaering the entire property line.

Any advice or suggestions would be greatly appreciated.

To my best knowledge this is not possible with the stock DJI app.
Maybe with waypoints or litchi, but I have no experience with that.

check out the drone deploy trial,  it should do what you need.
