Which screening method is used to detect metallic objects during visitor entry screening?

• A. Metal detector searches.
• B. Verbal questioning.
• C. Fine art analysis.
• D. Footprint analysis.

Answer: (A)

Metal detector searches are used because they directly detect metallic objects by creating a magnetic field and sensing disturbances when metal passes through or near the sensor. This makes them the quickest and most reliable way to flag weapons or metal contraband during visitor entry screening. Verbal questioning may uncover intent but cannot reveal metal; fine art analysis and footprint analysis are unrelated to detecting metal objects. Therefore, the correct method is metal detector searches.
