The product is really good, Im glad I bought it.

In general, the device is good. Requires some patience and skill in the search. I was rescued several times in places where it was necessary to hang the TV next to the outlet and it is not clear where the wires to this outlet come from. And I also determine gold for them. Can you tell if it's a gold chain or a ring ; )

  • Lightweight, compact. Case included. Backlit screen. The sound is turned off. Three operating modes. Looking for wires and fittings.
  • Deep-lying cable or fittings will not be found. Not always correctly determines the center.

All is well, liked the product, didn't buy it for nothing.

Everything is great, under the factory seal, it is only necessary that nothing extraneous work at the work site (as I have 2 TVs and a router), in this case the readings will be maximum to reality, it is better to work with rubberized gloves.

  • The price lies well in the hand, equipment, inspires confidence.
  • There are false positives

Bosch is Bosch is assembled soundly, the equipment is fully consistent with the declared. It was taken for a brick house, in these conditions the device fully justified itself. Got pros: It was used in the house mainly from a brick and a decorative brick. For these conditions, it confidently determines metal structures and electrical wiring in accordance with the declared characteristics. Cons: In a house made of reinforced concrete structures, things are objectively worse, there are more false

The best price for such a product, I will buy more!

One unbroken wire pays for the cost of the detector. When working, you need not be lazy and look not only at the color indicator, but also at the display. In "suspicious" places it is necessary to repeat the control many times. Got pros: Adequately shows black metal and wiring. I was not interested in wood. Cons below: Didn't see any problems. It works somewhat worse on embossed tiles, which is quite understandable: there is no high-quality contact.

Has pros: If you get a repair and you don’t know where the wires go in it, it does its job quite well. It makes no sense to compare it with professional devices 5-10 times more expensive, but for the money it's a great thing. Pretty comfortable, backlit display and speaker are very good. In simple cases (that is, the wires run strictly horizontally or vertically, and not scattered, say, in spirals), everything that is needed will be shown. Cons below: It requires compliance with certain rules i

The quality is at the level, I am satisfied with everything.

Convenient, functional. My wife has a "mulk" - pictures. At work, the headache is tenants. It is necessary to remake, outweigh, re. Etc. This device is a life saver. Tip: if "easy to use" is intended, remove the battery from the case. Time "back and forth" will not take, but it will save your nerves (there are all kinds of batteries).

The best purchase in my life, I will definitely buy it again.

excellent product. however, the aliexpress marketplace does not provide warranty cards for Bosch products. They answer all appeals that tomorrow they will contact you and provide everything, as a result, they are dynamized and sent to other specialists. Can't solve a basic issue. Before you want to buy something from aliexpress. Ru - think a thousand times. If there are problems with the product or something is missing, you will be left with this problem yourself. They got money from you and…

The product is working, I will not repeat it for sure.

Has pros: Displays the wiring. I have never checked, therefore I have no idea how accurate it is. Customers report that it performs miracles for them. In general, it gives you the ability to drill with confidence. The item performs well and is easy to use. It is effective, and there is little room for error while using it. Cons: There are hiccups every so often. You are well aware of the poor quality of Soviet electrical wiring; somewhere in the socket, a contact makes contact with the wall; as

The right product for me, the price suited me.

Has pros: An great alternative to devices for locating reinforcement in structures made of reinforced concrete. Defines the trace in an accurate manner. In contrast to the same SEARCH 2.5, this product is made up of a single block. Another feature that proved useful was the marking hole in the case. Finding what you're looking for in wiring may be done easily and quite accurately. Excellent value for the purchase price. Below are some downsides: There is no evident alternative available…

One of the best offers, glad I bought it.

Some pros: Specifically for the electrician, catches the wire, and the gadget can be purchased. Having this drawback: Sometimes it gives what are known as "false positives," and other times it does not detect wiring that is not functioning properly.

Valuable purchase, nothing but pluses!

Has pros: Finds, the electrical wiring is fine; you only need to employ it in the appropriate manner. Having these drawbacks: Because of the current price, I only bought half as much; if it weren't for that, I would buy another one so we could operate together.

Performs its functions, nothing unusual.

-purchased in order to check for the presence of wiring in the wall and floor prior to "drilling" In general, he shows fittings wherever he goes, but he doesn't show any wire in the wall at all. He also checked the area around the sockets, and everything there is green. In addition, he does not demonstrate any wiring in the floor, despite the fact that it is unquestionably present. he doesn't use it for the purpose for which it was purchased. the first of several Bosch power tools that were…

  • great level of craftsmanship, and the control is easy to understand
  • issues with the detection of hidden wires

A good product, but having its own defects.

In general, I took this device, because now I have to work a lot with drilling in an apartment in a panel house with repairs from the developer. For 2 months - I did not break through 1 armature and 1 wire. But there are nuances: 1. The search mode for wiring in reinforced concrete is practically useless. Relatively accurately grabs the wiring only if it is sewn close to the edge (in the gate in the protective layer, + -1 cm from the edge). And then the reinforcement in the deep layer gives…

  • 1. Does its job, but with some limitations. It should be understood that this is a fairly simple and "cheap" device, you should not expect any magic from it. 2. Drywall, wood, brick, foam / gas blocks will normally probe a few centimeters deep, including the search for wiring.
  • 1. Often catches interference and reacts nervously to sudden movements of the device. 2. Does not work properly with monolithic walls. 3. The accuracy is relative, to be 100% sure - you need to take much more expensive devices.

Good device for the price. If money allows, you can take it for 30-40K. - it will be the best option, with all the goodies and nice things. Its pros: In principle, everything suits. The best option for searching: wiring, metal profiles or wooden beams in the walls. No need to wait for miracles for 5K. Everything works quite well. Its cons: Powered by a 9 volt battery. It would be better if they did something rechargeable, with recharging. Could borrow a recharge from the Chinese.))))

Pros: Shows wiring. How accurate - I do not know, never checked. It has a magical effect on clients. In general, allows you to drill confidently. The device is good and comfortable. It does its job, it's hard to go wrong with it. Cons: Glitches intermittently. You yourself know the quality of Soviet wiring, somewhere in the socket the contact touches the wall, as a result, the device considers the entire wall to be one large wire. Or for some other reason this happens. Not too often, but someti

Took for repair. To avoid accidentally drilling a live wire. There were several places in the apartment where the wiring runs under a layer of plaster or tiles. I scanned from the outlet and found all the wires that someone once laid obliquely. Now I can safely drill or ditch without fear of damaging the wire. There are only two ways I know of to find a wire in a wall. Scanned or continue. With this contraption, the process is quick and painless. (No dust and noise ;-) You can also find rebar…

  • Locates wiring in the wall with good accuracy.
