PSA: A ground guy in Tacoma called me out on my hand signals
I was setting a big AC unit on a roof last month, and the spotter said my 'lower slowly' signal was too fast. He told me, 'Your hand is moving like you're swatting a fly, I can't tell the speed.' I started making my palm face down and moving it an inch at a time, way more clear. Has anyone else had a signal corrected on site that made a real difference?
