What is Hand Held Metal Detector?
Hand held metal detector is designed for quick and efficient body search scanning for knives, weapons and concealed metal objects. Metal detector wands offer a practical, low cost alternative to airport style walk through, arch type detectors which are designed for rapid scanning of high volumes of people. Hand held metal detectors are often used in conjunction with walk-through metal detectors, enabling operators to scan a person’s body to locate exactly where metal objects are concealed. They are extremely easy to operate simply requiring a single sweep across a subject’s body or across a bag or container, to detect hidden metal objects.
How do Hand Held Metal Detectors Work?
Metal detectors use electromagnetic fields to actively detect the presence of metallic objects. A hand held metal detector wand has two primary components, a transmitter coil that creates the electromagnetic field and a receiver coil that detects electromagnetism. An electromagnetic field is generated around the transmitter coil which extends to around 20cm from the security wand. When the wand is passed over a subjects body, if a metal object falls into the generated electromagnetic field a further electromagnetic field is induced around the hidden metal object. This new electromagnetic field is detected by the receiver coil which will trigger an alert for the operator.
Applications of Hand Held Metal Detector
Security metal detectors are now widely used almost anywhere that groups of people gather. Here`s a short list of typical locations:
- Airports
- Train Stations, Bus Stations and Ferry Terminals
- Schools, Colleges and Universities
- Top Hotels
- Conference Centers
- Concerts and Pop Gigs
- Events, both indoor and outdoor
- Public Buildings
- Door security at nightclubs.
- Football stadia or other sporting events.
- Music festivals and other events.
In order to avoid the risk of being accused of bias or victimization when scanning randomly selected subjects it’s important to ensure that selection is entirely random. Our Random Search Selector ensures that operators will not be accused of bias or prejudice by ensuring genuinely random selection.
Advantages of Hand Held Metal Detector
- The feeling of safety can be created while in an airport, college, office building, or any other area where these detectors are being used. People that are using them can control who enters a specific area and what’s brings inside it.
- With the help of a hand held detector, security personnel can physically detect if a person is carrying a metallic object.
- How metal detectors work is quite simple – they use the principles of electromagnetic induction to detect metallic objects. The detection of a dangerous object is notified with an alarm.
- Metal detectors are able to deter potential would-be criminals because the would-be criminal will think twice before walking through a security check point.
Types of Metal Detectors
Metal detectors are categorized based on how they are used and the items they detect. There are three main types of metal detectors: Very low frequency (VLF) detectors, pulse induction (PI) detectors, and specialty detectors.
- Very Low Frequency (VLF) Detectors: Very low frequency (VLF) detectors are the most common and affordable types of metal detectors. A VLF detector has two coils: a transmitter coil that creates the magnetic field and a detector coil that senses any disturbance in the field created by conductive materials.
- Pulse Induction (PI) Detectors: In contrast to the VLF detector’s two-coil design, Pulse induction (PI) metal detectors have just a single coil. This one coil transits the magnetic field and detects conductive materials. PI detectors’ single-coil design is less affected by ground mineralization than VLF detectors, which is why it’s better to use PI detectors when searching beaches, rivers, or underwater.
- Specialty Detectors: Specialty metal detectors such as multi-frequency detectors, gold detectors, and waterproof detectors can be either VLF or PI detectors, but they also have functions that enable them to execute specialized tasks.
What to Consider When Choosing the Best Metal Detector
Before choosing a metal detector, take a few minutes to think about the ways you’ll use it to find hidden treasures, and the features that will help you do this.
- Target Type
- Discrimination
- Ground Balance
- Target Identification
- Operating Frequency
- Metal Sensitivity
- Search Depth
- Product Weight
