Developing a Combined Method for Detection of Buried Metal Objects
Detection of buried metal objects (BO) has many important applications in the construction and operation of utility infrastructures, civil engineering, geological surveying, archeology, forensics, and geophysical logging, as well as treasure hunting and mine/weapon search [1,2,3,4,5,6].For instance, public utility infrastructures are nowadays How the Vlf Detector Works. The Vlf detector works by detecting and amplifying very low frequency electrical signals. The power source provides the necessary energy to the sensing element of the device. This element then amplifies the signal and passes it on to the output. The output is usually connected to an alarm system, which will circuit diagram of vlf detector Wiring Diagram

First, prove that the metal detector works by placing a spoon on the table. Run the detector over the spoon and listen for the detector to beep or give off a new sound (different from the steady tone that it is producing). Now, you can take it outside or around your house to locate other metal objects. Method 2.Consider another homemade metal detector called “VLF Madera metal detector” that requires a minimum investment and not so much knowledge to assemble. The uniqueness of the metal detector is that it does not have a round coil, as in classic models, but an oval (or almost square) shape. The type of metal detector can be attributed toVLF Madera metal detector Pulse Induction Metal Detectors

The difference between PI and VLF metal detectors
Here are the differences, along with their pros and cons. VLF stands for very low frequency and PI stands for pulsed induction. VLF technology is found in most metal detectors. VLF transceiver coils measure the phase shift between the transmitted and returned frequencies. PI detectors send pulses of current through their coil (s) and VLF metal detectors are more sensitive to ground mineralization than PI Detectors, which can lead to false signals and decreased performance in highly mineralized areas. Ground mineralization can cause the detector Types of Metal Detectors: VLF, PI, and BFO Gear Up.

After that I made all the required connections and put metal detctor to the test!The circuit diagram of a VLF metal detector typically consists of four components: an oscillator, a mixer, a detector circuit, and a power supply. The oscillator is responsible for generating an alternating current in the coil that is responsible for detecting metal. This alternating current creates an electromagnetic field which can sense thecircuit diagram of vlf metal detector Diagram Board

The AT Pro is a single frequency, VLF detector, operating at 15 kHz. Features of the AT Pro are: 6 search modes, adjustable discrimination, manual ground balance, target ID, programmable target ID, 12 target ID segments, depth indicator, and pinpoint mode. It can also operate in standard or professional mode.Phase shift provides VLF-based metal detectors with a capability called discrimination. Since most metals vary in both inductance and resistance, a VLF metal detector examines the amount of phase shift, using a pair of electronic circuits called phase demodulators, and compares it with the average for a particular type of metal.
