Best one I've tried
on 17 June 2014
I've grown really weary of these things having bought and lost faith in around 5 devices before this. Some were generic rebadged products by (for example) Draper and others were more expensive offerings by Black And Decker. I abandoned all of these quite quickly. I totally get the feeling that you're working with a device that is just random/bonkers/rubbish, I've gone through it with all my previous detectors. However, in my experience this Bosch device is excellent. It found pipes where I was expecting to find pipes, and cables where I expected to find cables. But it also found a few other things - worrying anomalies. I seriously need a device I can trust having probably wasted about £250 on several other devices and as I was working on a wall that needed various things filling anyway I investigated (carefully!) and uncovered the anomalies. A few were plasterboard nails. Another was an old (dead) cable. I went further and asked my kids to hide various small metal objects such as screws and bits of cut off 15mm copper pipe beneath a large sheet of plywood about 3/4 inch thick and it had absolutely no issues finding them. What I can say is that you do need to learn to interpret the readings. The manual states that when you find an object you should move over and around it a few times. Something happens when you do this, the device is likely tweaking the gain setting of the detector to match the object, and as you move toward and away from the object (the signal level is shown in the LCD display) you get a really good impression of exactly where the hotspot is. Pretty quickly you can narrow down if it's a pipe running vertically or horizontally or if it's an object such as a screw or nail.
I bought this device despite the negative reviews because I've not had anything from Bosch that let me down (unlike Black & Decker, that's another story) and I'm really glad I did. I can't comment on other users experience, maybe they did have bad devices and there's a quality control issue. Then again, maybe, like me, they live in an old house and their walls are full of the crap and detritus of every DIY job undertaken since the victorian era. I won't be sending mine back :)
