It’s essential to note that the effectiveness of a metal detector depends on factors such as the type of targets you’re searching for, the ground conditions, and your level of experience. Additionally, newer models may have been released since my last update, so it’s advisable to check for the latest reviews and models that suit your specific needs. Always consider your intended application and the features that are most important to you when choosing a metal detector.

Powerful Pirat metal detector with his own hands

Such metal detectors can be bought for about 100-300 dollars. The price of metal detectors is strongly interconnected with their depth of detection, not every metal detector can “see” coins at a depth of 15 cm. In addition, the cost of metal detectors is still strongly affected by the presence of a detector type of metals well and the type of interface, fashionable metal detectors sometimes equip the display for convenient work.

This article will look at the example of assembling a powerful metal detector called Pirat with your hands. The device is able to capture coins underground at a depth of 20 cm. As for large objects, it is quite real work at depth and in all 150 cm.

This name is given to this metal detector because it is pulsed, it is the designation of its first two letters (PI-pulse). Well, RA-T is in tune with the word radioskot – this is the name of the site developers, where was laid out and homemade. According to the author, going pirate is very simple and fast, it will be enough even initial skills in working with electronics.

The disadvantage of such a device is that it does not have a discriminator, that is, it does not know how to recognize non-ferrous metals. So to work with him on contaminated various kinds of metals will not work.

Materials and tools to build:

– THE KR1006VI1 chip (or its foreign counterpart NE555) – it builds a transmitting node;

– Chip K157UD2 and transistor VS547 (they are assembled by the receiving knot);

PEV 0.5 wire (for reeling);

NPN-type transistors

Materials to build the case and so on.

Isolent;

The rest of the radio components can be seen on the diagram.

You also need to find a suitable plastic box for the installation of the electronic scheme. You will also need a plastic pipe to create a rod on which the coil is attached.

Step one. Create a circuit board

The most difficult part of the device is, of course, electronics, so it is advisable to start. First of all, you need to make a circuit board. There are several board options, depending on the radio elements used. There is a fee for THE NE555, and there is a fee on transistors. All the necessary files to create a board are there to the article. Also on the Internet you can find other options for boards.

Step two. Install electronic items on the board

Now the fee needs to be soldered, all electronic elements are installed exactly as on the scheme. In the picture on the left you can see the capacitors. These capacitors are film-based and have high thermostability. This will make the metal detector more stable. This is especially true if you use a metal detector in autumn, when the street is sometimes quite cold.

Step three. Power source for metal detector

To power the device you need a source from 9 to 12 B. It is important to note that the device in terms of energy consumption is quite voracious, and it is logical, because it is powerful. One battery crown here for a long time will not be enough, it is recommended to use at once 2-3 batteries that connect in parallel. You can also use one powerful battery (best charged).

Step four. Collect a coil for a metal detector

Due to the fact that it is a pulse metal detector, here the accuracy of the coil assembly is not so important. The optimal diameter is a 1900-200 mm frame, all you need to reen 25 revolutions. Once the coil is rewound, it should be wrapped well on top of the tape to insulate. To increase the depth of the coil detection, you need to reel it on a frame with a diameter of about 260-270 mm, and reduce the number of turns to 21-22. The wire is used with a diameter of 0.5 mm.

Once the coil is rewound, it should be installed on a hard body, it should not be metal. Here you need to think a little and look for any suitable body. It is needed to protect the coil from impact while working with the device.

Conclusions from the coil are glued to a long-distance wire, with a diameter of about 0.5-0.75 mm. It’s best if it’s two wires.

Step five. Setting up a metal detector

When assembling exactly according to the scheme to adjust the metal detector is not required, it already has the maximum sensitivity. To fine-tune the metal detector you need to spin the rheastor R13 variable resistor, you need to achieve rare clicks in the dynamics. If you achieve this only in the extreme position of the resistor, you need to change the denomination of the R12 resistor. The variable resistor should adjust the device to normal operation in the middle positions.

If there is an oscillograph, it can be used to measure the frequency on the t2 transistor shutter. The pulse duration should be 130-150 mx, and the normal working frequency is 120-150 Hz.

How to work with a metal detector

After turning on the device, you need to wait about 10-20 seconds for the metal detector to stabilize. Now you can spin the R13 resistor to set up. After that, you can start searchinge.
