Top 10 wiring detectors

This device of the “home” class is extremely simple: the entire display of it is the “traffic light” of the indicator lamp, which changes its luminescence from green to yellow when approaching metal and to red - when it is impossible to drill at this point. Moreover, the constant burning of the red signal means just metal, and the blinking red signal means wiring under voltage.

Using Truvo is also easy - turn it on. Calibration is automatic. The corners are provided with marking corners that will quickly mark dangerous places. Please note that the device is designed to search for exactly the wiring of a household AC network of 110-240 V with a frequency of 50/60 Hz, and, for example, it will “see” the DC bus like a normal metal with lower accuracy. The depth of detection of hidden wiring here is traditional for this class - 50 mm, Truvo steel reinforcement can feel at a depth of up to 70 mm, and “tsvetnin” - at 60. For household needs is enough.

Power supply - three AAA batteries. To be honest, a built-in battery would be much more appropriate - the device would still hardly work from one shift to another without being connected to a power outlet, and you can recharge from USB in our time everywhere, even to bus stops.

A good universal detector that can “see” wiring under voltage at a depth of 50 mm, steel - up to 120. When searching for de-energized wiring, you will have to rely on a “color” mode with a maximum detection depth of 80 mm. Tree search is possible at a depth of up to 38 mm.

The display of the device is double - a liquid crystal display and a “eye” rim that changes color, through which you can immediately mark the place found with a pencil or thin marker. However, it is worth noting the feature of the device, which is not always paid attention to (it’s customary to read the instructions when something breaks, as you know): the device’s auto-calibration time after switching on is at least 8 seconds, and all this time it should be guaranteed it is distant from metal, otherwise it will begin to show if not “the weather on Mars”, then “the average temperature in the hospital” - exactly. Also, do not forget about manual calibration, fulfilling the conditions specified in the same instructions.

A curious feature of the GMS 120 is a separate “drywall” mode, in which, by the way, the device can also find plastic pipes with water. The rest of the set of modes is traditional - "metal", "non-metal", "wire under current".

Alas, despite belonging to the "blue" professional series, the device is not attributed to the truly professional - this is not the case when the "Bosch" everything turned out as planned. The device is still not enough "long-range", and elementary capricious to working conditions.

But this is already a serious "universal" of the professional class, albeit with an appropriate price. He recognizes metal at a depth of up to 150 mm, wiring under voltage - up to 60. He and plastic pipes with water “see”. The power source is again batteries (although in Bosch levels, for example, they have already begun to replace standard lithium-ion batteries), but at least not the damned “Kron”, but 4 AA batteries that can be replaced with batteries of the same size.

The display at the detector is informative, but Russification is killing - it issues all messages in transliteration, like “Dvigat” or “Kabel pod napryaz”. For an expensive device, it looks strange - although, perhaps, razrabotchiki simply re-read Burgess and started a gadget on a nassat? But the signal viewing mode (the one called Prosmotr signala ... no, we’d better in English - Signal View) is often able to show even two adjacent valves separately, rather than as a single object: the accuracy is excellent. Additionally, a useful mode of measuring raw concrete separately from dry is introduced, which is so lacking in cheaper instruments.

A very interesting device that is specifically designed to search for wiring, including deep, and not necessarily a household network under standard voltage. However, more precisely, it is not one device, but two: the detector itself and the transmitter. The principle of detecting wiring is simple: the transmitter creates a high-frequency current in the wire, which is easier to catch even at a decent distance than the standard several tens of hertz. At the same time, a transmitter connected to an accessible end of the wire (for example, to a power outlet whose power supply we are looking for) shows the voltage across it. The signal generated by the transmitter is encoded - thanks to this, you can use several transmitters at the same time, placing a different code on them so that they do not interfere with each other, and the receiver can immediately show which particular line has been found.

A serious advantage of detectors with its own signal generator is the ability not only to find the wire as such, but also to detect the place of a hidden break. So the functionality of the CEM is really more than worthy.

As to the minuses, we note that both the transmitter and the receiver are powered by “Kron”. But, if you can use a bipolar connection when working with household wiring (the transmitter switches to mains supply), the receiver does not have a “spare” power supply. So the supply of "Kron" in the case is worth making, even with modern 9-volt batteries, the capacity is not impressive.

Well, nevertheless, we advise you to read the instructions before use, although this is for a Russian person and not typical - this will avoid misunderstandings and the banal misuse of the detector.
