Using hand-held magnetometers (wands) as back-up for additional screening with fixed screening equipment is NOT an effective use of this screening equipment.

• A. True
• B. Sometimes
• C. Not effective at all
• D. False

Answer: (D)

Hand-held magnetometers provide flexible, targeted screening that complements fixed screening equipment. Fixed detectors can quickly screen large crowds, while a handheld wand allows security personnel to localize and verify the exact location of a metal object after an alarm, or to follow up when a suspect item is suspected but not clearly identified. This layered approach also helps when fixed equipment is down, when space is limited, or when screening a specific person or area without running everyone through a fixed device. Because the wand adds precision and adaptability without dramatically slowing throughput, using it as a backup to fixed screening is an effective practice.
