That's really cool to see the Solo being used in that circumstance, but really, I'd use a Phantom for better range and longer flight time...Mavic better still...both easier to transport to the flying location if a person is walking in.
And use Drone Deploy to upload a search grid, press a button and let the DJI product just go do it while watching the FPV in goggles. (I know the Solo can do that as well, but the Phantom/Mavic/Drone Deploy is just so damn quick/simple.)
