Shopping guide

Whether you need to check electrical wiring or carry out a repair, to avoid damaging an internal pipe and finding yourself with a metal beam that will not allow you to drill, it is necessary to use a detector.

Fortunately, the market today offers a wide variety of cable detector models that allow you to locate different materials with varying depths. However, if you don’t know much about these devices, and you don’t know what you should take into account when making a choice; You should not worry, since we have prepared the following guide to buy the best cable detector.


If you are wondering how much a cable detector costs, it is important that you keep in mind that manufacturers offer a wide variety of models and prices that fit any user, therefore, before making your investment, take into account what use you will have. you will give In this way, you can avoid unnecessary spending or, on the contrary, that a very cheap model does not provide a solution to your needs.

In this sense, try to learn a little more about the functions offered by cable detectors, as well as the different types and models that exist.

sensor type

In any comparison of cable detectors, one of the most important aspects that you must take into account is the choice of the appropriate device for the work that you are going to carry out. Since each user has a different need, manufacturers have tried to cover them by offering various types of detectors.

These devices can be separated into two large groups, first of all the specific detectors and the multifunctional ones. On the one hand, the specific models are usually used by technicians and industry professionals. In this case, you can find models such as telecommunications cable detectors, which help locate and check analog telephone networks and local area networks or LANs. Also in this line, you can find models that specialize in detecting electrical wiring or pipes, being suitable tools for electrical engineers and builders.

On the other hand, multifunctional models are those that allow different types of materials to be located with the same device, being sensitive to wood, steel, copper, wiring and pipes. However, depending on the quality of the detector and the type of material you are looking for, the depth of detection can vary.

depth and precision

This is one of the most important technical characteristics to consider when evaluating what your new detector will be. As we mentioned before, depending on the type of device and material you need to locate, the depth of the search varies considerably. However, almost as a general rule, metallic materials are the ones that emit a stronger signal, being able to reach depths of 10 centimeters or more.

Others, such as wood buried in a wall, ceiling or floor, are usually less noticeable, so it is common to find detectors that locate wood up to 2 centimeters deep. Finally, if you want to locate a power cable, possibly a detector that reaches about 5 centimeters will be your alternative.

On the other hand, not only depth comes into play, but you will also have to analyze the precision or sensitivity of the device. This is very important so that the detector can correctly discriminate or recognize the material you are looking for. Keep in mind that a model that is too sensitive could give you erroneous reading data, increasing the chances of committing an accident.

On the other hand, if it is not very sensitive, it will not be able to give a clear signal of what it recognizes. This is why manufacturers have incorporated new automatic adjustment and calibration systems, which must be well understood in order to get the most out of the detector.


Finally, although many users let this aspect go completely unnoticed, the reality is that it is very important to pay attention to the design of your cable detector due to several factors.

In the first place, it is advisable to acquire one that is compact and light enough so that it is not cumbersome to carry and use, considering that you will use your hand to pass it over the surface several times until you locate the object.

Its manufacturing material must also be of quality and, if possible, with an ergonomic handle and a non-slip texture. This will allow you to hold it comfortably and more securely when maneuvering the detector.

In addition, some models incorporate a practical screen that makes it easy to see the strength of the signal and the precise location of the object, even indicating the location of the center of the object. Similarly, some screens make use of backlight technology, which allows the device to be used at night or in dark rooms.

Frequently asked questions


Q1: How to use a cable detector?

First of all, you will have to put the detector into operation and select the mode you want, whether you want to locate metal, wood or cables and calibrate it correctly. Proceed to place it on the surface and move it along the area where you think a pipe or other material may be.

You will notice how the lighting or proximity alert turns on and it will emit an acoustic signal. If this is the case, you will also be able to see the location of the center of the pipe on the screen and follow it while marking its direction with a pencil. You will also be able to know the depth of objects, so that you can drill more safely.

Q2: How to make an electric wire detector?

If you need to locate some electrical cable lines that are inside the wall that you are going to drill, the indicated thing is to use a cable detector. However, if you’re short on budget and don’t want to spend a lot of money on professional equipment, you can opt to make your own. 

Before you think that making one of these gadgets on your own is a complicated task, rest assured, it is actually quite the opposite.

To carry out this task, you will only need to have three bipolar transistors and a few components. You will quickly get a voltage amplifier with a gain of 6,000,000, as well as a presence detector that receives the signal from the static electricity emitted by buried objects.

Keep in mind that you can easily find this connection diagram on the net to carry out the union of all the components.

Q3: How deep does a cable detector work?

The depths at which these devices work is highly variable, so depending on the type of detector and the quality of its internal components, the intensity of the received signal will be greater or lesser. Also, keep in mind that depending on the type of material, the depth of the signal also varies considerably.

Normally, ferrous materials and cables are the ones that generate the greatest static signal, so they can be located at a greater depth than materials such as wood. Normally, a medium quality locator will be able to locate a metal object to a depth of 6 centimeters or more, while wood to about 3 or 4 centimeters.

Q4: What pipes can a cable detector detect?

Cable detectors typically detect pipes made of iron, steel, chrome, and even copper. All depending on the type of cable detector you have.

Q5: Does a wall cable detector work to detect buried cables?

Yes, the cable detector market offers users models that allow them to locate cables and other objects that are buried up to a certain depth. These devices are often used to track the location of pipes, wood and electrical and telephone wiring lines, which are found both in the walls, ceilings and floors.
