Shot the beam of my Sanwu Striker 7.5W blue laser with a DJI Mavic Pro 2 quadcopter from an altitude of 400 feet.
That does show how badly these diverge. I'll bet you even had a beam expander on it. I've got everything I need to build a cylinder lens corrected NUBM44 and the host takes a Sanwu 3.3X BE. As soon as I finish my current project, this one it next in line. Thanks for sharing your video here.
