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.

Absolutely useless, this will detect metal and cables in a spot then say it’s fine minutes later, we tried all sorts to get this to work properly, following the instructions carefully, recalibrated numerous times. The final straw was checking it on a pane of glass, which it decided had live cables and metal in it… returned for a refund, don’t waste your time

Just moved and the pipework and cablings all over the place so was getting a bit stressed about fixing stuff to walls so I got this and it just seems to work so well in our house. I know a lot of people have had issues with it, maybe wall thickness or material composition of pipes has a roll but this thing is spot on for me. Even if you know a bit about building regs and have some common sense you can predict roughly where many cables and pipes will be but the peace of mind from this is great.

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.

Product as described.

I bought this because I was a bit worried about drilling blindly through walls especially as I know roughly where there may be pipes and electricity. The trouble with this is that it is too sensitive and it literally picks up everything including the smallest bits of metal and is therefore not very reliable to follow. If I were to trust this wholly, I would not be able to fix anything to the wall.
