Dual-Switch Handheld Security Metal Detector Scanner

The MD3003B1-D Dual-Switch Handheld Security Metal Detector Scanner is a versatile, commercial-grade security wand engineered for intensive body screening, loss prevention, and access control. Operating at 22KHz with low standby power consumption (<5mA), this ergonomically balanced 360g scanner efficiently detects ferrous and non-ferrous metals, including razor blades, pins, handguns, and steel spheres.

Equipped with a dual-switch control interface, the MD3003B1-D allows security personnel to independently select between sound/light alarms and silent vibration mode, as well as press-and-hold the side low-sensitivity switch to lower sensitivity by over 5 times for filtering out harmless metal clutter. Complete with a manual sensitivity adjustment trimmer, an external 10V DC charging port, and constant-voltage battery regulation down to 7V, it provides a dependable inspection solution for transit terminals, courts, events, and industrial plants.

Dual-Switch Mode Selection

Features separate, independent switches for audio/vibration mode toggling and low-sensitivity activation, giving security operators complete tactile control during inspections.

Press-to-Hold Low-Sensitivity De-Tune

Includes a side low-sensitivity button that reduces sensitivity by over 5x when pressed, enabling guards to ignore micro-metals and focus strictly on larger hidden weapons or contraband.

Reinforced 360g Structural Housing

Crafted with a solid 360g reinforced housing designed to endure demanding commercial use and high-throughput checkpoint environments.

Constant Sensitivity Across Battery Discharge

Internal voltage stabilization logic maintains consistent detection depth and performance even as the standard 9V battery power drains down to 7V.

40+ Hour Battery Autonomy with Charging Jack

Consumes minimal standby power (<5mA) for over 40 hours of operation. Includes a built-in 10V DC charging socket for direct in-unit battery recharging.

Public Transit Hubs & Border Customs

Provides reliable, high-throughput body and luggage checks at airports, ferry terminals, railway stations, and border checkpoints.

Judicial Systems & Government Buildings

Inspects visitors, staff, and contractors at courthouses, detention centers, and secure administrative facilities.

Precious Metal Plants & Loss Prevention

Prevents unauthorized removal of raw gold, electronic components, and high-value tools in manufacturing plants.

Q1: What is the key difference between the MD3003B1-D and MD3003B1-S models?

A: The MD3003B1-D features a dual-switch control interface and a 360g reinforced housing for versatile operation in high-traffic commercial environments, whereas the MD3003B1-S uses a single-switch layout with an ultra-lightweight 230g body.

Q2: How does the low-sensitivity function work on the MD3003B1-D?

A: Pressing and holding the dedicated low-sensitivity switch reduces detection sensitivity by over 5 times, allowing security officers to bypass small harmless metals (like shoe eyelets or zipper teeth) and quickly scan for larger metallic objects or weapons.

Q3: Does the scanner lose detection distance as the battery drains?

A: No. Built-in constant-voltage regulation maintains stable detection depth and sensitivity even as battery power drops from 9V down to approximately 7V.
