Rating of the best detectors of hidden wiring, plastic pipes and metal for 2020

Construction, repair, home improvement is one of the priority activities of a modern person. Well, when it comes to cosmetic repairs or simple rearrangements. But such a trifle as drilling a wall can bring many 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 accidental drilling method is not suitable because a short circuit or powerful electric shock may result.

A special device - the detector not only detects electrical wiring and other inclusions in wall panels, but also determines the location of the break in the telephone, Internet cable.

How the detector works

A special scanner generates signals. Radiation penetrates into the investigated medium, then there is a return reflected signal, which has either original vibrations or changed, in accordance with the composition of the underlying object.
The device moves in the plane in four possible directions, which makes it possible to determine the length, density, and possible breakage of the built-in 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.

What are the search devices for hidden objects

All modern devices designed to assist in the implementation of construction work can be divided into three types:

1. detectors of hidden wiring;
2. route finding devices;
3. identifiers of electromagnetic fields.

Search instrument models are distinguished by several parameters.

Indication

When wires and structures are identified, notifications are made in various ways.

• Light indication

The system operates on LEDs. For materials of different compositions, certain color indicators are triggered.

• Sound alert

The period of duration of the sound signal and a certain tonality informs about the characteristics of the internal object.

The liquid crystal display gives the most complete information about the internal structure.
Some models have all types of indication, such devices are expensive.

How to choose the right detection detector: selection criteria

There is a wide range of domestic and foreign devices, with features and an individual range of functionality.

The quality and usability depend on the basic parameters of the technical device.

Detection depth

The technical data sheets of the devices 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 the 5 cm mark.

Accuracy

The classic error is measured in the size 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 of occurrence and the characteristics of the breaks it is able to determine.
Manufacturers do not guarantee the final result in full, since it is difficult for a layman to take into account many related factors when measuring.

The main risk factors for reduced accuracy are:

• induced electric, magnetic fields of high values;
• many included in the array of transactions;
• material and composition of the wall, its moisture resistance, conductivity;
• the presence of metal hooks, loops and other items in the array.

Experts recommend insuring yourself during work by additional familiarization with the design and construction documentation.

Internal object material

A good device can distinguish between a number of identified materials:

• wiring;
• non-ferrous metals;
• black metals;
• fittings;
• plastic pipes;
• wooden structures.

Autocalibration

The device independently grades the materials of both the occurrence and the studied massif.

Disabling "Automatic"

The detectors are characterized by high power consumption, therefore, it is important to turn off the device at a given period of inactive phase, which saves batteries.

Backlight

The use of detection scanners involves their operation in darkened rooms, in areas with no power supply, which determines the high value of having a backlight for convenient and accurate work.

Price

The budget option for a price does not go beyond the boundaries of 1,500 rubles.
The average price level is from 2,000 to 6,000 rubles.
All scanners from 7000 and up come with specifications suitable for professional use.

Where to buy a detector

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 place an online order with a choice of payment options and delivery methods.

Selection errors

What to look for when choosing a detector.

Electromagnetic device

The most inexpensive type of cable finder for locating a 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, which does not belong to low-power devices, you can get a positive detection result. Connecting a consumer with a weak impulse to the network will not allow the electromagnetic detector to be triggered.

In new buildings, empty buildings, premises subject to redevelopment, such devices are unacceptable for operation.

Repair and replacement

You should not count on the possibility of eliminating the malfunction that has arisen by repairing or replacing the device under warranty. In such cases, the manufacturer stipulates the purchase of a new detector in advance.
