Give me a Model 3 with a 44-3 and I'll find 1KCPM all day long in NYC. But not at drone levels, 300-400'.
Did a job in Philly and was doing drive around surveys on a dreary day. Found 16KCPM while traveling through a railroad overpass. But, I failed to convince the EPA to shut down the train traffic to rebuild the overpass.
Fun times.
