Every property manager, school administrator, or security officer eventually faces the same question when planning a screening checkpoint: do we install a walk-through metal detector, hand out handheld wands to guards, or run both together? The right answer depends less on budget alone and more on foot traffic, the layout of your entrance, and what level of screening your organization is expected to maintain.
How walk-through detectors work
A walk-through metal detector is a fixed archway that screens everyone passing through it, using multiple detection zones to flag both the presence and general location of metal on a person’s body — chest, waist, ankles, and so on. Modern units used across Philippine malls, schools, and government buildings support adjustable sensitivity, so operators can screen out small, harmless metal objects (belt buckles, coins) while still catching weapons.
Best suited for: high-traffic entrances — mall main entrances, school gates during peak arrival hours, event venues, government buildings with sustained visitor flow.
How handheld detectors work
A handheld metal detector (often called a wand) is a secondary screening tool. A guard sweeps it over a person who has already alarmed at a walk-through unit, or uses it as the sole screening method at lower-traffic entrances where installing a fixed archway isn’t practical. It’s also the standard tool specified in DepEd’s current school safety guidance — more on that below.
Best suited for: secondary/confirmation screening after a walk-through alarm, low-traffic entrances, mobile or temporary checkpoints, smaller campuses and offices without the space or budget for a fixed unit.

Side-by-side comparison
| Factor | Walk-Through | Handheld |
|---|---|---|
| Throughput | High — screens continuously as people pass through | Lower — one person at a time, guard-dependent |
| Upfront cost | Higher | Lower |
| Staffing required | 1-2 operators per unit | 1 guard per checkpoint, more guards for multiple entrances |
| Installation | Fixed placement, needs entrance space | Portable, no installation |
| Typical setting | Malls, large schools, government buildings, events | Smaller schools, offices, secondary screening, mobile checkpoints |
| DepEd current guidance | Not the specified minimum | Specifically named in DM 189 s. 2026 |
Many facilities use both. A walk-through detector as the first line of screening, with handheld units for secondary checks on anyone who alarms, or for entrances too small to justify a fixed installation — this layered approach is standard for malls and larger school campuses.
What this means for your procurement decision
If you’re a school administrator working through DepEd’s current safety directive, handheld units are the specified starting point. If you’re managing a mall, corporate lobby, or high-traffic venue, a walk-through unit at the main entrance paired with handheld units for secondary screening and side entrances is the more typical setup.
