How to Choose the Right Walk Through Metal Detector
Selecting a security metal detector depends on your facility type, foot traffic volume, detection sensitivity requirements, and budget. Here is what to evaluate before you buy.
Single-Zone vs. Multi-Zone Detection
Walk through metal detectors fall into two categories. Single-zone models detect the presence of metal but do not indicate where on the body the object is located. Multi-zone models — available in 6, 18, 20, 33, and 66 zone configurations — pinpoint the exact location of the detected item using LED indicator lights on the side panels.
For high-traffic facilities like courthouses, airports, and large events, multi-zone walk through metal detectors with 18 or more zones are strongly recommended. They process visitors faster and give your security team actionable information with every alarm.
Sensitivity and Discrimination
Higher-end security metal detectors offer adjustable sensitivity settings — typically between 100 and 200 levels — that let you fine-tune detection thresholds for your environment. Models like the Garrett PD 6500i and the Zorpro 33 Zone include built-in discrimination settings that help distinguish between threatening and non-threatening items, reducing false alarm rates while maintaining strict security.
Portability and Installation
Every walk through metal detector we sell can be assembled in under 30 minutes without professional installation. Models designed for events and temporary deployments — such as the Garrett MZ 6100 and the Zorpro 6 Zone — are lighter, include optional caster wheels, and can run on battery backup power for outdoor use.
For permanent installations in courthouses, schools, and government buildings, heavier-duty models like the Garrett PD 6500i and Garrett Paragon offer network connectivity, directional counters, and advanced security lockouts.
Walk Through Metal Detectors by Application
Walk Through Metal Detectors for Schools
→ View All School Metal Detector Solutions
School security has become a national priority. Walk through metal detectors provide a visible deterrent and an effective first line of defense at school entrances. The most popular models for K-12 schools include the Zorpro 6 Zone and the Garrett MZ 6100, both of which balance affordability with multi-zone detection accuracy.
Key considerations for school metal detectors include ADA-compliant clearance width (32.5 inches minimum), battery backup for portable deployment during events, and quiet operation settings to avoid disrupting the school environment.
Walk Through Metal Detectors for Courthouses
→ View All Courthouse Metal Detector Solutions
Courthouses require the highest level of security screening with minimal disruption to daily operations. The Garrett PD 6500i remains the gold standard for courthouse security — its 33 pinpoint zones, TSA-level certification, and dual-panel detection make it the most widely deployed courthouse metal detector in the United States.
For courthouses with tighter budgets, the Zorpro 33 Zone offers comparable 33-zone detection technology at roughly 40% lower cost, with the same 2-year warranty and U.S.-based support.
Walk Through Metal Detectors for Events and Venues
Concerts, sporting events, conferences, and festivals need walk through metal detectors that are fast to deploy, portable, and able to handle high foot traffic. Models with optional caster wheels, battery backup modules, and quick-connect assembly are ideal for temporary event security.
We also offer walk through metal detector rentals for short-term events. Rental units ship tested and calibrated, with clear setup instructions and free phone support.
Walk Through Metal Detectors for Government Buildings
→ View Airport & Government Security Solutions
Federal, state, and municipal buildings require security archway metal detectors that meet or exceed national screening standards. The Garrett PD 6500i and Garrett Paragon are both deployed in U.S. airports and government buildings worldwide, offering network connectivity for multi-unit management.
Walk Through Metal Detectors for Loss Prevention
→ View XVS Loss Prevention Detectors
Manufacturing plants, warehouses, and distribution centers use walk through metal detectors to prevent employee theft of metal components, tools, electronics, and raw materials. Our Zorpro 33S Loss Prevention model and the XVS 10mi Ultra Sensitive are specifically designed for this application, featuring advanced reporting software that logs every alarm event.
Walk Through Metal Detector Prices: What to Expect
Walk through metal detector prices range from approximately $1,495 for a basic single-zone model to over $7,500 for a top-tier 66-zone security archway. Here is a general pricing breakdown by category:
Entry Level ($1,495 – $2,500)
Single-zone and basic 6-zone models like the Zorpro ZS1 and Zorpro 6 Zone. Best for small businesses, churches, and low-traffic entrances where budget is the primary concern.
Mid Range ($2,500 – $4,000)
Multi-zone models with 18 to 33 detection zones, adjustable sensitivity, and ADA compliance. Includes the Zorpro 18 Zone, Zorpro 33 Zone, and Garrett MZ 6100 — the most popular category for schools, courthouses, and event security.
Professional Grade ($4,000 – $6,000)
High-performance models with advanced discrimination, network connectivity, and dual-panel detection. The Garrett PD 6500i and Fisher M-Scope fall in this range and are trusted by airports, government buildings, and correctional facilities.
Maximum Security ($6,000+)
Top-of-the-line models like the Garrett Paragon with 66 detection zones, 200 sensitivity levels, and ECAC certification for the most demanding security environments.

How Walk Through Metal Detectors Work
Walk through metal detectors use pulse induction (PI) or continuous wave (CW) electromagnetic technology to detect metal objects on a person’s body. Each detector contains transmitter and receiver coils built into the side panels. When powered on, the transmitter coils generate a controlled electromagnetic field across the walkthrough portal.
When a person carrying a metal object — such as a firearm, knife, phone, or set of keys — passes through the archway, the metal disrupts the electromagnetic field. The receiver coils detect this disruption, and the detector’s processor analyzes the signal to determine the size, location, and composition of the object. The system then triggers an audible alarm and illuminates LED zone indicators on the side panels to show security personnel exactly where the item is located.
Modern security metal detectors can distinguish between ferrous metals (iron, steel), non-ferrous metals (aluminum, copper, brass), and metal alloys (stainless steel). Higher-end models use multi-frequency scanning and digital signal processing to improve accuracy and reduce false alarms from everyday items like belt buckles and coins.
Walk through metal detectors are safe for all individuals, including pregnant women, children, and people with pacemakers or implanted medical devices. The electromagnetic fields produced by these detectors operate at extremely low frequencies — well below the levels produced by common household electronics like cell phones and computer monitors.
