A metal detector is an electronic device that gives a signal when it is close to the metal. Metal detectors are devices that use electromagnetic fields to find metallic objects. These devices come in different models like portable metal detectors or wall-mounted metal detectors but all of them feature the same main function that is detecting metal. These detectors are mainly used in large industries like building, military, and construction. Most handheld metal detectors are compact and lightweight making them ideal for tailoring to your needs.
Types Of Metal Detectors
There are 3 main types of metal detectors named very-low-frequency detectors, pulse induction detectors, and specialty detectors.
- Very Low-Frequency Detectors (VLF)
VLF detectors like Bounty Hunter TK4 are the most affordable and common types of metal detectors available. This VLF detector comes with 2 coils. A transmitter coil creates a magnetic field and a detector coil to sense any disturbance created by conductive materials. These types of detectors are also lightweight and durable making them great for beginners.
- Pulse Induction Detectors (PI)
PI detectors come with a single cord design. This coil creates the magnetic field and also detects conductive materials. This coil is also less affected by ground mineralization. These detectors are great for searching beaches, rivers, or underwater. The customer reviews of Garrett 1140900 Pro-Pointer show that it is waterproof and perfect for working underwater.
- Specialty Detectors
These detectors include a variety of detectors like frequency detectors, gold detectors, and waterproof detectors. Specialty detectors can be both VLF or PI detectors. These detectors have the ability to execute specialized tasks.
Parts Of A Metal Detector
The three main parts of a metal detector are the control box, the shaft, and the coil. Some models also come with a stabilizer to detector steady. All these parts are replaceable in case of any damage. The control box contains the speaker, batteries, and microprocessor. The shaft connects the control box and coil. A search coil is a part that senses the metal.
Depth Detection Of Metal Detector
The depth of a metal detector depends on target size, target shape, target orientation, and target material. A metal detector can find larger targets faster than small ones. Target shapes like coins, rings, and flat rectangular objects are easier to detect. Flat lying targets are easier to detect than vertical ones. You can detect high electrical conductivity metals faster.
Market Overview
A metal detector is a handy as well as a portable tool. It consists of a device that can detect metal objects in the ground. Metal detectors are also widely used in archaeology to locate metal objects buried underground. These detectors can search for coins, jewelry, as well as other valuable items. Another widespread application of the metal detector is the military. The market overview of metal detectors is enhanced because of their efficiency and detection power.
