How des 33 zones walk through metal detector work

The 33-zone walk-through metal detector is a medium-high precision security screening gate equipped with 33 independent detection zones. It sits between basic 6-zone and top-tier 45-zone models. It can accurately locate metal objects on the human body without the extra cost of the highest-end 45-zone version. Widely deployed in courts, prisons, government buildings and high-value factory checkpoints.
