The circuit diagram of the metal detector on Arduino with metal discrimination is shown in the following figure. When metal is detected, the device will emit a sound signal, and the LCD display will display the proximity of the metal using a bar graph, as well as indicate the type of metal – iron (ferrous) or non-ferrous (non-ferrous).

One of the main problems when developing a good pulse induction metal detector with digital signal processing is a proper design of the power supply. The system will contain three power users which each their own specific needs. Peak currents in one part of the power supply should not have any negative effect on other parts in the system.

VLF metal detectors work by sending a constant alternating current through a coil which, due to the polarity being reversed thousands of times per second, creates a transmit frequency that is sent into the ground. If this transmit signal encounters metal, a signal which is opposite in polarity to the transmit coil is produced within the object.
The SSP-3100 Digital Discriminator is a unique combination of Metal Detector and Magnetometer that works hand in hand to detect "Eddy Currents" and "Ferrous Metals". Using Pulse Indection technology you can quickly discriminate between Ferrous and Non-Ferrous metals.
History of A.H. Electronics and the now Vintage Metal detectors from 1970-80s and still in use today. A.H. Electronics was issued a Patent on the first "true" discriminating metal detector with several later patents on enhancements and a patent on the first "Ground Balancing" metal detection system. A list of products manufacturered is shown below.

The Tesoro Pantera is a VLF discriminating metal detector that was produced around 1990 by Tesoro Electronics. It had a cult following due to its proficiency in extracting non-ferrous targets from dense ferrous trash. Information on it is rare so I am reproducing the material from the catalog pag...
This article presents an oscillator-free pulse generator using direct digital-to-impulse technique. The pulse generator is based on an all-digital phase discrimination circuit fabricated in a standard 65 nm CMOS process. A 55.6 mV output pulse with an 18.9-ps full width at half maximum can be achieved.
Hello All, I don't have a lot of analog experience and would like opinions on this circuit. General parameters and goals: Take a gaussian-ish shaped input pulse on the order of 100-200 ns wide at 50-200 mV received randomly and at rates "as high as possible", maybe high kHz to low mHz range. Bring this pulse up to a sharply defined …
Digital designs don't have that problem, but they do have the problem you bring up. Every disc or notch setting can have (and probably does have) a "brick wall" cut-off. With digital discrimination it's a none-or-all situation, unlike analog disc where it's a none-or-a-lot-less situation.
2: Components and Materials Needed for Construction To build a high-range pulse induction metal detector, you will need several key components and materials.These include a microcontroller or Arduino board, a pulse generator, a power supply, a search coil, capacitors, resistors, diodes, and transistors.
