DFMD vs HHMD — What's the Difference?

Last updated: 6 Jul 2026Reviewed by Ms. Rubab Nizami, Lead AVSEC Faculty

In short

A DFMD (Door Frame Metal Detector) is the walk-through archway that alarms when a person carries metal. An HHMD (Hand-Held Metal Detector) is the wand a screener passes over the body to pinpoint that metal. The DFMD detects; the HHMD locates.

Which should you use?

You walk through the DFMD; if it alarms, a screener uses the HHMD to find the metal. They work together.

Quick answers

Is a DFMD the same as an HHMD?
