Bosch Detector Truvo 2nd gen. (Easy one-Button handling, Simple Detection of Live Cables & Metal Wall Scanner up to 70mm, in Cardboard Box)

There is a knack to getting the best out of this unit, and unlike other such devices I've used before I had to actually read the manual to get the best out of it. But once you establish a consistent way of holding it, and a consistent sweeping pattern, then you get perfectly accurate identification of metal and electrical current in a cavity wall.Like I say, it has two detection capabilities it alerts on: metal and current. I was trying to trace and verify the exact location of a mains cable to avoid drilling into it, and was bemused as it seemed to pick up a second cable a handspan to the right which had no current. This second cable turned out to be a satellite coaxial cable. So I'm very happy that I didn't drill into either cable.Great tool, but a bit more fiddly than the ones I used to use about ten years ago... But also more accurate once you get the hang of it. Expect lots of beeping while you trace your way to safety. Definitely staying in the top of the toolkit.

Certainly detected some wiring we know to be there, but other results were puzzling. I suspect it depends on your walls. I couldn't find a better rated one at time of purchase and the Bosch build quality is as expected.

Bought a cheaper no branded version but couldn’t make head nor tail of it so returned and bought this Bosch version which does exactly what it says it will. Easy to use and understand, highly recommended.

The media could not be loaded. Bought one to find where the live wires are to be able to fit some wall cabinets. The wire behind the plasterboard is 0.5cm wide. The device will detect it on a 10cm width.I understand it is not a professional tool with laser that cost 1000+, but having the live wires just behind the plasterboard (so not even 2cm depth) it is kinda useless

The media could not be loaded. Hi, I bought a £19 cheaper wall detector, and the performance was awful. But this Bosch does the job done. In the video, there are 3 marks on the wall where I planned to drill. We bought the place over a year ago and did not know what was in the walls.When I used a cheaper detector, it showed me a No Drill area almost anywhere on that wall even though it's solid brick. apart from above/down or sideway from the sockets where a wire is laid.Even a child can use this tool, and its performance is outstanding for £38.Recommended!

I like the simplicty but the meter doest perform very well. Stud and or elecs/metal found where there is none. Instructions say to hold it in a particular way and with other hand on the wall. (Standing on one foot while wearing a funny hat too for all the difference it makes) Back face has plastic studs and will leave marks on the wall if you run it over the wall. My old beat up meter is still better than this one.

Love this little tool. Very simple to use. DIY in an old house is always a bit scary as you never really know what you're going to hit when you drill into a wall...will it be water, wood, gas or electricity?! This tool has definitely helped reduce the chances of screwing things up & may even have saved my life on one or two occasions!

So I read the 1 star reviews and the general vibe is that it goes off randomly so can't reliably tell where the wires and pipes are.Sure enough, when I received it, I followed the quick guide and took off my Apple Watch, kept my feet bare and started testing - it was going off wildly at places that shouldn't have anything. I was testing this at my in law's house, my FIL rewired the house himself over the years and knew exactly where the wires and pipes were, and the Truvo definitely picked those up, but also going off where there shouldn't be anything.He suggested that we should put our hands on the wall, and it definitely made a difference, but we were still getting weird readings at places.Finally I pulled out the thick instruction manual (not the diagram only quick guide), and read through the instructions. There are still no mentions of putting your other hand on the wall, even though it clearly made a difference. But what interested me was when I got to the recalibration instructions.I followed it, made the mistake of doing each step at a time first try when one of the steps required 0.5 seconds timing; second try also didn't work as I waited half a second and probably went over the time; third time, flicked the switch off and on and it started blinking to indicate recalibration.Tried it after, the reading's much more stable now. The light switches, outlets, etc. all worked as expected. Empty wall no longer triggered readings. There's still one socket we're not sure about but FIL said maybe he was wrong about it as it might have come through the back of the fireplace. Everything else seems to check out.So yeah, my advice: Dig out the manual and recalibrate it first. Then when using it, in additional to the instructions, put your other hand on the wall as well - like in all the photos (but not the instructions).
