Construction, repair, home improvement is one of the priority activities of modern man. Well, if we are talking about cosmetic repairs or a simple rearrangement. But such a trifle as drilling a wall can bring a lot of problems if simple safety standards are not followed.
The reason lies in hidden wiring, pipes, fittings laid in brick and panel arrays, under floor coverings.
How to identify the place where the electrical wire is located. The random drilling method is not suitable because the result can be a short circuit or a powerful electric shock.
A special device - a detector not only detects electrical wiring and other inclusions in wall panels, but also determines the location of a telephone or Internet cable break.
Content
A special scanner generates signals. The radiation penetrates into the medium under study, then there is a return reflected signal, which has either initial vibrations or modified ones, in accordance with the composition of the underlying object.
The device moves in a plane in four possible directions, which allows you to determine the length, density, possible breakage of the embedded system.
To obtain the result, sound and color indicators are used, the display gives detailed parameters.
The modern consumer is offered mainly devices made in digital format.
All modern devices designed to assist in the implementation of construction work can be divided into three types:
Models of search instruments are distinguished by several parameters.
When identifying wires and structures, alerts are produced in various ways.
The system operates on LEDs. For materials of different compositions, certain color indicators work.
The period of duration of the sound signal and a certain tonality informs about the characteristics of the internal object.
The liquid crystal display provides the most complete information about the internal structure.
Some models have all types of indication, such devices are expensive.
There is a wide range of domestic and foreign devices, with features and an individual range of functionality.
The quality and ease of use depend on the main parameters of a technical device.
Device datasheets indicate the maximum scanning depth for various types of material. In the case of active voltage in the wires to be detected, the standard is at around 5 cm.
The classical error is measured in the amount of 5 mm, a non-professional meter can give an error of up to 10 mm.
The more expensive the device, the more accurate the depth and characteristics of the breaks it is able to determine.
Manufacturers do not guarantee the final result in full, since it is difficult for a non-professional to take into account many related factors when measuring.
The main risk factors for reducing accuracy are:
Experts recommend insuring during work by additional familiarization with design and construction documentation.
A good level device can distinguish between a number of identified materials:
The device independently performs gradation of materials of both the occurrence and the studied massif.
The detectors are characterized by high power consumption, so it is important to turn off the device for a given period of inactive phase, which saves batteries.
The use of detection scanners provides for their operation in darkened rooms, in areas with a power outage, which determines the high value of having a backlight for convenient and accurate work.
The budget option at a price does not cross the borders of 1500 rubles.
The average price level is from 2,000 to 6,000 rubles.
All scanners from 7000 and above carry specifications suitable for professional use.
There are options for purchasing equipment on order from specialized online stores, from AliExpress and, directly, in shopping centers of the city. It is not difficult to make an online order with a choice of payment options and delivery methods.
What should you pay attention to when choosing a detector.
The most inexpensive type of finder for finding the location of the live cable. The peculiarity of such a device is that it will react to the wiring only if it is under load. By turning on, for example, a multicooker that does not belong to low-power appliances, you can get a positive detection result. Connecting to the network of a consumer with a weak impulse will not allow the electromagnetic detector to be activated.
In new buildings, empty buildings, premises subject to redevelopment, such devices are unacceptable for operation.
You should not rely on the possibility of eliminating the malfunction by repair or warranty replacement of the device. The manufacturer stipulates in advance in such cases the purchase of a new detector.
The detector from a world-renowned German manufacturer, which occupies a leading position in the production of high-quality electrical equipment, has a wide functionality.
The detector detects wiring, wooden internal structures, metal, including colored wire systems.

The use of embedded object detection detectors at the first stage of design guarantees cost savings by eliminating erroneous actions and damage from eliminating the consequences of technical miscalculations. In addition to the economic component, scanners will save the nerves of builders and the most precious thing - time.
