Metal and hidden wiring detectors: concept, types, principle of operation
Hidden wiring detector
How to find a live cable in the wall? In such situations, you cannot do without a device for searching wiring. It is quite simple and has a wide range of uses. It is used during renovations of apartments and houses to find wires in a concrete or, for example, wooden wall. Also, detectors are often used in the process of car repair.
The operating principle of the device is based on the generation of certain vibrations. The device generates them itself, so it easily reads the vibrations that come from the wiring and sends a signal to the diode. It starts flashing, notifying you that wires have been found.
All detectors are divided into three categories:
- testers;
- indicators;
- metal detectors.
The first ones are simple and highly reliable. But they are recommended for indoor use, as high humidity levels can create unnecessary interference. Also, testers do not react well to steel; it is a strong interference for detecting wires. Despite this, the devices have found wide application, being used in various fields.
Indicators are even simpler, but they only “see” wires under high voltage. Therefore, their range of operation is greatly limited.
Classic metal detectors, by their operating principle, cannot be classified as effective devices for detecting wiring, since they react to any metal objects. As a result, the process of searching for wires may drag on indefinitely. But still, in some situations such devices will be useful.
Important! Detectors are widely available on the market. Therefore, initially decide on the type of device and only then start looking for a suitable model in the store.
Professional detectors
Detectors belonging to this group guarantee detection of the desired element with maximum accuracy. However, the cost of such devices differs significantly from those previously considered. If any of the budget or medium-sized radars can be purchased for home use (own construction), then purchasing professional devices will simply not be economically feasible. Therefore, they can only be found in the hands of real specialists.
Bosch D-tect 150 SV Professional, 42,900 – 45,800 rubles
Premium class detector Bosch D-tect 150 SV Professional Source 6.allegroimg.com
The best wiring detector for professionals with a corresponding price tag. Finds metal fittings at a depth of up to 150 mm, live cables at a depth of 60 mm. Able to recognize plastic water pipes, it runs on classic AA batteries. Among the distinctive advantages of the device are the following:
- The presence of four most necessary sensors for detecting metal, wood, plastic, and electrical wiring.
- Possibility of pre-classification of materials for greater safety.
- Auto calibration option.
- Compact design and excellent ergonomics.
- Maximum detection depth, up to 15 cm.

The Bosch D-tect 150 SV Professional uses Ultrawideband technology, which ensures maximum accuracy and determination of the desired material. The signal is played only when the device is in direct contact with the wall and moves. When a pulse intersects with extraneous signals (propagating from mobile phones, Wi-Fi router, remote control), an error notification is displayed on the screen. In this case, the operator needs to repeat the search process from the place where the overlap was detected.

Leading manufacturers of sensors for detecting hidden wiring
Wire and metal detectors are produced by many companies. If you have never purchased such devices before, then focus only on the most famous and reliable manufacturers:
- Rexant . A domestic company that does not produce products itself, selling items produced at Chinese industrial sites. Devices from this brand are affordable and quite reliable. Wiring sensors have different types of indication and are lightweight.
- Precision Mastech Enterprises Co . The Hong Kong company is in great demand on the market, since its testers are able to “see” even cables that do not work. In addition, they do not damage the insulation and are most often equipped with a display on which all information is displayed.
- Duwi. The company from Poland has been producing measuring instruments and other specialized products for a long time. Meters of this brand are in demand among professionals and ordinary people, as they are able to “see” wires at great depths. They are equipped with screens and a convenient notification system.
- Bison This Russian manufacturer is well known on the market. It produces lightweight and easy-to-use meters equipped with displays, backlighting and sound indication.
- Allsun. The Chinese manufacturer offers consumers very worthy products. It “sees” at great depths, is capable of working at low and high temperatures, and is also very light.
- Eltes. A company from Ukraine has been producing scanners for over 20 years. They are durable and have high sensitivity, thanks to which they even detect a break in the line.
- Bosch. Leader in scanner production. The company produces devices that scan walls to a depth of 7 centimeters. In addition, they recognize different metals and are extremely easy to operate.
How to choose a reliable hidden wiring detector: important criteria
The best detector for searching for hidden wiring is selected based on a number of parameters:
- Device type. Decide whether you need the device to distinguish between metals and be able to find objects made of other materials. Based on this, choose a tester, indicator or metal detector.
- Depth . The scanning range varies from 3 to 10 centimeters.
- Spectrum of work. It is determined by the buyer's objectives. Some need to “see” network wiring, others need to see non-ferrous metals, and so on.
- Error. For a number of wiring operations, a small error is acceptable, but there are situations where extreme accuracy comes first. For example, when searching for pipes.
- Additional features. They are relevant mainly for professional devices. But the display on which all the information is displayed is also interesting to ordinary users.
A hidden wiring detector is not a one-time tool.
With the right choice, it will help cope with various tasks and will serve for many years. The best hidden wiring detectors video

Bosch Truvo, 2,900 – 3,500 rub.
Inexpensive but reliable Bosch Truvo Source ali-buy.com
A device designed for determining electrical wiring at home. Notification of detection is carried out by changing the glowing green diode to red. In addition, the presence of voltage on the wire is reflected by the blinking of the light bulb; a uniform glow means that there is a wire or other metal object in the wall.
The “stuffing” of the device involves searching for a source of electricity with a voltage of 110-240V and a frequency of 50/60Hz. It will find a cable with direct current, but it will show it like an ordinary piece of hardware.
