6 best hidden wiring detectors

During repairs in a house or apartment, deep drilling of walls or ceilings is often required. However, there is always a high probability of getting into electrical wiring. On the one hand, this is a danger to the worker, on the other hand, there will be serious additional problems associated with the restoration of the damaged wire. The hidden wiring detector will help prevent a negative scenario. A small device can not only find wiring in the thickness of the concrete or under drywall, but also indicate to the owner the steel reinforcement or wooden structure. After studying the recommendations of experts, you can go to the store for this useful device.

How to choose a hidden wiring detector

1. Detection depth One of the main parameters of the hidden wiring detector is the depth of detection. In the technical specifications, the manufacturer indicates the maximum value for electrical wiring, wood, ferrous and non-ferrous metals. The optimal depth of a live wire is 5 cm. Serious devices on the display indicate the depth of the found object.
2. Accuracy. In order to minimize damage to the wall or ceiling during the repair process, it is important to pinpoint the location of the electrical wiring or plumbing. Professional devices demonstrate an error not exceeding 5 mm. For home appliances, an accuracy of 10 mm is considered normal.
3. Material definition. Since not only the electrical cable can be placed in the concrete or under the plasterboard, but also the fittings, the damaged wire, the plastic pipe or the wooden insert, it is important to correctly determine the type of object. Each manufacturer equips the device with light and sound indication, which may differ when the object is located. Decipher the signal will help instructions for use. For example, a non-ferrous metal is identified by a red circle, and live wiring is identified by a blinking red circle.
4. Auto Calibration. A useful option, especially for novice users, will be auto-calibration of the device. The owner does not need to manually enter data about the base material and type of object to be detected. The detector will do this work independently, minimizing the preparatory time.
5. Auto power off. Most hidden wiring detectors are battery powered. To save the charge level, many devices are equipped with an automatic shutdown function. It works if the device is idle for a certain time, for example, after 5 minutes.
6. Backlight. It is not always necessary to work with a hidden wiring detector in good light conditions. The presence of the display backlight becomes particularly relevant when repairing electrical wiring in the evening.

We have selected in our review of the 6 best detectors hidden wiring. All devices are approved by the expert community and received positive feedback from domestic users.

Bosch D-tect 150 SV Professional

Rating: 4.9

A serious search tool for professionals is the detector Bosch D-tect 150 SV Professional. This German specialist in the detection of reinforcing bars, non-ferrous metals and other objects in concrete is equipped with 3 modes of operation. The maximum depth of detection of steel and color parts is 150 mm. The electrical wiring is detected at a distance of 60 mm from the surface, and the wooden elements are fixed by the detector at a depth of up to 40 mm. After turning on the device, it is not necessary to adjust or calibrate it. The accuracy of the device is about 5 mm.

Professional installers wiring the device more than once rescued when the wiring had to look under the plasterboard panels or in concrete. Of the minuses can be noted only the high price.

Elitech D 100

Rating: 4.8

An excellent instrument for detecting various communications is the Elitech D 100 detector. The Russian design is made in China, due to which a competitive price has been achieved. Using the device, it is possible to detect ferrous and non-ferrous metals hidden in concrete or behind gypsum plasterboard, wooden structures or live electrical wires. To save battery capacity, the manufacturer has provided an automatic shutdown when the device is idle for 5 minutes.

The model loses to the winner of the rating in the depth of detection of ferrous metals (100 mm) and wood (20 mm), as well as in measurement accuracy (10 mm). Users praise the detector for availability and high-quality assembly, ease of operation. The disadvantages include fuzzy definition of a tree.

Bosch GMS 120 Professional

Rating: 4.7

Bosch GMS 120 Professional detector has a high accuracy in detecting hidden wiring. The maximum depth of detection of steel is 120 mm, the colors are 80 mm, electrical wiring is 50 mm and wood is 38 mm. The device takes the 3rd place at the expense of affordable prices. The search result is recorded on the informative display, a special scale indicates the center of the detected object. You can wear the device on your wrist thanks to an ergonomic strap. The presence of the backlight allows the owner to work in conditions of limited visibility.

Some users scold the detector without having read the instructions in detail. Therefore, it is not possible to detect even the wiring at a shallow depth. Perhaps the manufacturer should simplify the description of the device.

ADA instruments Wall Scanner 80

Rating: 4.7

Compactness and lightness (120 g) stands out from the competition of the Chinese concealed wiring detector ADA Wall Scanner 80. At the same time, the device is sold at the most attractive price. The device is designed to detect metals, wood and electrical wiring, but the depth of detection looks more modest than the leaders of the rating. In this way, a non-ferrous metal detector can detect in a concrete layer up to 60 mm thick, wood up to 20 mm, and steel reinforcement up to 80 mm. When an object is detected, a light alarm occurs, and the reading time of the results is 10 s. The time of continuous work is limited to 6 hours.

Users have no consensus regarding the quality of the device. Some praise him for accuracy and sensitivity, while others still do not understand how to use it.

Zubr Professional DX-750 45260

Rating: 4.6

Zubr Professional DX-750 detector is capable of detecting hidden electrical wiring at a depth of 50 mm, and steel reinforcement - up to 100 mm. Experts included this device in our rating for affordability and good performance. When objects are detected, multi-colored indicators appear on the display with which the identification of the material is simplified. The device is equipped with a discrete meter, thanks to the digital display it is possible to accurately determine the depth of the wiring.

However, it has a detector and a number of flaws that did not allow it to rise higher in the rating. It makes a very weak sound, the case has a tight battery compartment, and the LCD display has a small viewing angle.

Resanta DM-2 61/10/521

Rating: 4.5

High interest from domestic consumers allowed the Resanta DM-2 detector to get into our rating. Only in 2 months more than 10 thousand people were interested in the device at NM. First of all, the device looks attractive in terms of price. At a good depth, the detector finds ferrous (100 mm) and non-ferrous (80 mm) metals, electrical wiring (50 mm). Compared with the closest competitors in the budget segment, it looks somewhat more massive (weight 240 g). The uptime is 6 hours, when idle for 5 minutes, the device automatically turns off.

Users like comfortable grip, which provides embossed rubber inserts on the plastic case and a well-readable display. The disadvantages of the device include the lack of lighting and batteries included.
