      Very accurate at finding Wall studs. Sometimes Electricity warning goes off in a wall that definitely contains no wiring. Getting used to its intricacies now. Yes it’s a lot more than some devices, but what value would you put on the cost of having to have a Plumber/Electrician, then a builder for repairs to your dismantled wall + plastering and re-decorating to get it back to the state it was in just before your drill went through in the wrong place? Looking at it that way I decided 200 odd was a worthwhile investment…

      Golden Review Award: 4 From Our UsersI think overall this is a solid product. Bosch have shown that the technology they use in the higher end products is actually much cheaper to produce in this model, but I feel like this one is ‘artificially’ dumbed down so as not to break their revenue stream on the more expensive models that pro’s will buy day in day out. It seems pretty accurate, and 95% consistent, but does leave a little to the imagination and hoping that you’ve got it right. You have to be gentle – go slow and go over the area multiple times. Its a pain to hold, and thats the most annoying thing about it. The handle is actually just part of the overall one piece case, so you have to kind of grip it without connecting your hand all the way around. Its fine for a short while, but can be tiresome for longer periods.

      Golden Review Award: 3 From Our UsersI’ve never felt very confident with wall scanners, often feeling a little dubious about results or failing completely to get a consistent reading. I felt the same about this Bosch Pro D-tect 120 at first and was quite underwhelmed. Despite the tool seeming fairly straightforward, a good read of the manual and a good understanding of the display’s icons is a must. The screen, at first, felt a little like a gimmick, but it just needs some experience to learn how to get the most our of it and it really does give a big improvement over audio only scanners.

      The last time I used it I was much more impressed than the first few attempts, maybe because (due to the price and the size) I was expecting a lot more from it at the start. After more time using the tool I appreciate it needed some learning from different use cases and now I feel a lot more confident about what it is telling me. It is probably a bit overboard for an amateur DIYer like myself and I would be hard pressed to justify the expense if I hadn’t received this review version. Even now, it still feels like a lot of money for what you get, but I’m not really the target audience, I feel, as my previous scanner, 100 pounds cheaper, gives results not far different to this one. Given the choice now, I use the D-tect every time, as it is more practical and complete.

      What this tool did do was introduce me to the Bosch Pro 12V System cordless range and I’m thankful for that, as I absolutely love the other tools in the range. The battery and charge in this bundle can be reused across the range, meaning you can get the other tools on their own for considerably less than you do if the battery and charger are included. I’ve now got 4 tools from the Bosch Pro range and absolutely love them all, even this scanner.

      For the Pros, this is probably a good buy as the extra level of feedback you get from the screen saves time and gives more reassurance in locations where you have no knowledge of the walls you’re working on.

      Got this during the Amazon Prime event (2020) for a price lower than anywhere else on the interweb including eBay…
      I’ve used it a couple of times already (on dot and dab walls) and it is absolutely brilliant the best, most accurate wall scanner I have used…
      First job was hanging three 68cm (dia) mirrors on a wall with 2 double sockets and a radiator fed with plastic pipes. The scanner easily traced the routes for both the wires for the sockets and the plastic pipes for the radiator.

      This is a very high quality detector – it looks good, has a good display and seems to work well. The kit i received includes the charger and battery, which is very good.

      It’s always worth cross checking detection to make sure it works as expected, but for me it seemed to work very well and very easy to use. Complements all the other Bosch blue tools as well.

      Golden Review Award: 2 From Our UsersYou really need to practise using it for a while to understand how it works and get used to it. Try it in your shed, hold a few examples of things behind the door or something similar. This is not a criticism of the tool. Practice does make perfect. I was convinced when i received this product it was too sensitive receiving cable signatures. The electricity detector was sounding off every time i got even somewhere close to a cable.

      So a few pointers.

      Do not expect to get an accurate reading by putting straight on the wall and doing a simple single pass. It has auto sensitivity which means you need to get a few passes carried out before you get an accurate result.
      Look for the second meter to show the centre dot as it passes over known wires.
      Get used to when the meter starts sounding/flashing verses the location of known wires and when it just shows a solid dot. Look for the centre-dot to appear as you move across the wall, keep going over the area – at least a few sweeps.

      As it approaches something it detects it from a longer distance than the reverse. A few sweeps either side will give you the most accurate reading.
      Make sure you hold it properly and avoid holding it by the head. Holding it by the head seems to really confuse the accuracy. And remove any rings and watches you may have on your hand/wrist. This again can cause confusion.

      Keep your other hand on the wall. Possibly earthing yourself to the wall would give you a better reading? If you are charged with static it might affect your reading.

      This is a professional tool which requires a good amount of preparation to ensure best results.

      100% confidence when using this item.

      I have a standard Bosch detector and this one is much more accurate, as it should be with the price difference.
      It needs a bit of practice to use and get the “swiping” speed correct. It gives a visual display and a bleep loud enough to hear even in a noisy environment.
      You do wonder about the thought that went into the design however. It came in an enormous plastic carry/storage box that looks like a multi function box with a variety of sections.
      Much is made in the blurb about being also able to use it with AA batteries, this is possibly true but the adapter is not supplied and does not seem to be available from Bosch either.
      The rechargeable battery seems to last for ever particularly as this is not a device that would be in continuous use.
      I think a better design would be for the battery to be built in and have a phone type charger which would make everything more compact and get rid of the need for the big box which could be replaced with a case/holster which would make it much more usable.
      Incidentally spare batteries do not seem to be available from Bosch either.

      Golden Review Award: 2 From Our UsersThis Professional Detector is of a very good quality with an exact and fast determination of the structures of the material that is in the wall. It is used very easily and comfortably.

      Golden Review Award: 3 From Our UsersPriced for the trade, this could be of interest to a home renovator who want to locate pipes, wires and studs before a major house remodel.

      The unit is supplied in a Bosch L-Boxx case, together with rechargeable battery and charger. As this leaves ample space, the case includes a plastic tray for a Bosch Professional cordless drill. Once you ‘buy into’ the Bosch Professional range, the batteries can be used interchangeably.

      The Detector is simple to use with three modes for masonry, plasterboard and concrete with rebar walls. When moved across the surface, the ‘beeping’ and display shows the location of the detected object. Live wire cause the red LED to blink and a ‘live conductor’ indicator comes on.

      In use, I found the detector worked a specified and was even able to locate a ceiling rose through floorboards in the floor above. It’s not sold for the purpose, but it can also locate ferrous nails etc. in lumber before running it through a saw.

      I’d like to see a couple of improvement –

      1) The essential instructions on a laminated card to tuck into a pocket on the L-Boxx lid
      2) Low friction pads on the underside to minimise risk of marking when sliding the unit over painted wall surfaces

      This detector arrived in a very large but mostly empty tool box which appears to stack to other tool boxes. There is a charger, battery and instructions included.

      Using it is simple. You turn it on with the detector against the surface you are detecting through and then select the material from the three choices. Moving the unit side to side across the wall will give audible and visual indications of something behind the wall. If there is electricity present it will beep and flash.

      On my plasterboard walls it seems to be very accurate, finding the centres within a few mm. In some cases it can be a little bit too sensitive, finding things on the other side of the partition, but with a but of patience and some common sense it is straight forward to interpret the readings and find what you are looking for.

      It is a bit pricey for the casual user but for the professional you do get what you pay for.

      5.0 out of 5 stars Sensitive and accurate detector.

      Golden Review Award: 3 From Our UsersThis is the best detector I have used to date and it is better at detecting live cables and water pipes than anything I have used in the past.

      I should clarify that I am a confident DIY’er (I know when to call someone in) rather than a pro-user and have had close calls with almost drilling into power cables (within 1mm) and water supply pipes (I actually drilled directly into one of those, but noticed a change in the pitch of the drill and stopped before I caused a leak). I have used many different detectors and have never felt 100% confident in their accuracy; I am not at 100% with this either, but I am closer than I have ever been with a detector to date.

      This detector comes with a rechargeable battery pack and battery charger. A part charge is present on arrival but full charging before first use is recommended. I found the battery pack difficult to fit to both the detector and charger, something that I hope will ease with use.

      The things I am concerned most about finding are electrical wires and water pipes, having had near disasters with both in the past. This picked up electric cables without any trouble whatsoever, including the one that is buried in plaster and covered with travertine tiles in my bathroom (site of the near miss when I decided to hang a picture). I had a couple of false positives to start with, but that was down to my technique rather than a problem with the detector as they were not repeated subsequently. The display is easy to read and understand.

      Despite the large box, the device itself is relatively small and not cumbersome to use. The battery should last for about 5 hours of use before it will need to be recharged, so that should suit most domestic as well as pro-users. A full charge takes around 90 minutes.

      Note that it is supplied in a large, sealed tool box (no chance of ever losing this) with a serial number and warranty that the device has been tested before shipping. The box has a thin plastic insert that suggests you may also be able to purchase with a drill and other components, but there is definitely space in the box for other things to be added, although the plastic tray is unlikely to withstand too much heavy use.

      This is one of the best detectors I have used to date and should suit most DIY users, as well as many pros. The tool box is a little large for the device alone, but it does ensure the detector is kept safe and not misplaced. Plus there is room for you to add your other essentials.
