I joined the Trusted Traveler program to avoid this, the zapper machine, and to expedite entry into the country.
Also, lines are much, much shorter.
Yep pre check helps, i also pay the ~150$ or so a year for CLEAR
Saves me 30 minutes to an hour each time in a lot of airports...walk up to kiosk, look into retina scanner and get escorted straight to tsa precheck screening , no lore waiting on ID check
