NBA Arena Security has implemented new standards this season, with walkthrough metal detectors (WTMD) serving as the primary method of fan screening at all NBA games. These are now in effect at the BMO Harris Bradley Center for all Bucks games.
Minimize the number of personal items you bring to the game.
Remove from your clothing and belongings all heavy metal items that may trigger a WTMD alarm.
Hold those items visibly in your hand or, as a better option, place them in bins provided for inspection.
If the WTMD alarm sounds, you will be subject to a secondary screening which may slow their entry into the arena.
The NBA bag policy has not changed: all permitted bags must be searched thoroughly. Permitted bags should be soft-sided, not larger than 14” x 6” x 14” and able to fit completely beneath an arena seat. Bags that are fully packed take longer to search; clear bags and those packed loosely are more easily examined.
