Best laser range finder for 1 mile shots

Would your scenario be suited to something like a DJI Mavic Mini? It will fly that distance easily and give you readings on distance and altitude. A more robust drone and you probably mount a wind speed meter on top to measure speeds at various distances along the course as well.

You would be looking somewhere in the $500 range for a drone that is using gps for measurement.

I am a little scared to try and run a drone, but my interest is peaked.
