Bosch Cable Finder Truvo (Maximum Detection Depth Live Cable/Non-Magnetic Metal/Magnetic Metal: 50/60/70 mm, in Cardboard Box)
Digital detector
Truvo
How can we be certain where supporting elements, pipes or cables are routed in walls? The Truvo detector from Bosch detects ferrous and non-ferrous metals and live cables at depths of up to 7 cm.
Auto calibration
Practical auto-calibration for direct start-up and safer drilling.
Marking aids
Conveniently use the lines on the side of the tool to accurately mark results during operation.
Single-button operation
One-button principle with automatic calibration – simply use the ON/OFF button and begin scanning without further steps.
LED light
The LED traffic light system lights up red when an object has been detected, yellow when one is nearby and green when no object has been found.
-
Switching on the tool
Switch on the Truvo by pulling down the slider and placing your hand against the wall.
-
Keep moving
By moving back and forth, the Truvo memorises the course of the material and becomes more accurate.
-
Detecting the materials
Live cables and metals can be detected (see next step).
-
Traffic light system
Green: No object found
Yellow: Object nearby
Red (continuous tone): Metal
Red (flashing): Cable
-
Setting the marker
Using the marking slots, the target areas can be easily and accurately marked.
The Truvo
Why does the tool indicate live cables everywhere?
The construction of commercially available cables causes fluctuations in the electric field strength at the surface, which influence signal detection, through to complete elimination.
What should I do if the tool displays different results for the same measurement?
Follow the step-by-step guide when using the tool and make sure that all measurements are performed in the same way. In particular, move the tool three times in each direction – under constant external conditions.
Why does the signal change when the tool is moved along a live cable?
The construction of commercially available cables causes fluctuations in the electric field strength at the surface, which influence signal detection, through to complete elimination.
Why do I have problems locating three-phase power cables?
In the case of live three-phase power cables (e.g. power connection for the cooker), the different phases of the cable cancel each other out so that the detector cannot detect the signal.
Why does the tool indicate metal objects on the entire wall?
The tool detects certain construction materials as metal due to the high iron content (e.g. aluminium foil on underfloor heating systems or metal-clad thermal glass wool insulation).

Does the job
Easy to use and located cables we thought were very close to each other enabling us to get good and safe fixings
Expensive but does job
Easy to use. Rather sensitive to moisture interference when used in bathroom but not a major issue. Agree some sort of protective cover would be useful to prevent damage in tool box. Other than probably being overpriced because itsBosch a useful bit of kit for the amateur DIYis

A must have
I strongly advise any one to get it could potently save you life. I will always make sure I have one and I will buy a second one for a back up. It comes with bats which is a bonus

After reading a lot of reviews for this product, I was prepared for the fact that I might be returning it if it didn’t work as some reviews had mentioned that it just beeped at pretty much everything. I was looking to drill some holes in a wall to install a baby gate at the bottom of our staircase, but realised that our fuse box (although much higher up and further down the hall) was on the same wall, so assumed there was a chance that there could very well be wiring running along the wall and up our stairs. To make sure I didn’t cause any damage to any wiring I thought that checking with a device like this could be a good way of making sure it was safe to drill.
When I first got it out of the box and tested it, it did in fact beep at absolutely everything – wooden doors, a wooden table, and wooden bannisters all had wiring and metal in them! However, I have a habit of not reading instructions and expecting everything to just ‘work’ out of the box. So to make sure it definitely was faulty before sending back, I actually read the instructions and lo and behold it turns out I needed to calibrate the thing. So I gave that a try and it suddenly started working spot on!
I tested above and around light switches and it gave pretty accurate readings (if a bit sensitive) and wooden items no longer seems to be hiding electrical wires. Like another review I read, I think it works slightly better if you hold it slightly off the wall, but overall I am very glad I bought this. It lit up like a Christmas tree at the section where I was looking to drill, so I am happy to steer well clear.
Overall, very happy with this. If you want something that is going to be very accurate to the mm, this isn’t for you. But it does help to give you a pretty good idea if something is lurking in the wall. I also suggest to anyone who does get one and finds that it beeps at everything – calibrate it! And make sure you calibrate it properly, my first attempt didn’t have the correct flashing lights at the end, so had to do it a second time where I made sure I followed the instructions to the letter and it worked a charm.
For the price I paid, I am very happy.
Hope that helps!
Good wall senso
Happy with this Bosch sensor; it helped me install my wall sconces correctly. It comes with batteries and the device is pretty accurate, despite seeing bad reviews. I love it’s little “meep”, cute noise. Easy to use, idiot-proof!

Quality product and great service
Excellent responsive product. Will certainly pay for itself over and over with DIY. Easy to use too.
Bosch detecto
This is a quality product and well worth the money. We had to instal a new bathroom cabinet and needed to check for hidden pipes and wires before installation and the Bosch detector did it’s job.
Does what it says on the box
Was asked by my daughter to put up some shelves adjacent to her home alarm system, fuse box and externally her gas & electricity metres. Very congested area. The metre identified live electric cables, metal pipes & studding all within a couple of inches. I took a chance and accepted its verdict. All went well….no problems..

Brilliant tool could save your life
The product was brilliant used it to locate electric cables in wall also defined between live cables and dead cables.
The only downside it should have a case but no case delivered
Good product, reliable.
Bit more expensive than alternatives but good product, works well and detects within a certain range. Would recommend
very effective little gadge
Having moved into a new flat I needed to put up some storage and had no idea where the pipes and wiring were hidden behind the walls. This gadget allowed me to drill safely and avoid any nasty surprises. Very easy to use.
Simple to use
Seems to work well so far and not drilled into anything I shouldnt! 😉
Detector for cables and metal objects
I had an old metal detector for cables and pipes which eventually gave up the ghost. The one I have just purchased is as easy to use as the old one. I have only used it a few times so far but it seems to detect the cables and pipes quite easily and seems accurate.
Safety first...
Works a treat given I live in an old building seemingly wired by people more suited to pushing a piano up some stairs. This found live wiring where it should not have been, and where I was about to drill – so naturally I’m chuffed whilst the ex wife is less so.
Very effective and accurate
A new wall to drill holes into and it wasn’t obvious whether the cables came up or down behind the plaster. Within seconds I was reassured and knew where to drill. The unit is a good size to grip and appears strongly constructed.
where to drill
his was cheap item. I found it very useful for detecting live wires,pipes etc.It gave confidence when drilling into a wall.
Reasonably trust-worthy detector.
Hasn’t let me down so far and better than some alternative detectors from Bosch. Simple to use. Would have been good if this could also detect studs.
I have bought others before, some worked, some did not and what is worse, some looked like they were working and when tested properly were not – this one works and all of the time.
The only difficulty I had was when I first turned it on and went to calibrate it – a simple job of on, take batteries out, off, put batteries in, on and wait for the lights to stop flashing in a fixed time – easy – but for me it was not working, it just kept flashing on and on .
There is a tiny bit of text, with an asterisk at the very end of everything that tells you to beware electromagnetic interference, well I though surely not, my laptop is on the other side of the room, but I chose to do as another buyer had mentioned, and took it outside to calibrate – worked fine.
Turns out a laptop / computer gives off far more electromagnetic interference than I thought possible!
Since then we have used it frequently to drill holes for shelving, hooks, cupboards etc, looking to avoid pipes and wires, and to find the wall studs for handing cupboards on, and although there is a rule that all electrical wires should go straight up from a socket, turns out not all builders stick to this so much surprise was had finding things to avoid.
The sound is good and clear.
I am not an expert DIY’er and therefore it was super important that I have a piece of kit I can rely on. Well worth the extra cost.
To get a true reading you need to hold it on the wall and earth out placing your free hand
Simple to use and effective. Have used it two or three times with success.
Good - but use with caution.
A helpful tool, but how much total trust you would place on it, is questionable, because it is not 100% consistent. To be fair, the instructions do advocate running the tool across an area several times. Only identifies metal and live wires, but not location of stud wall supports.
looks like wizadry
When running this device along the wall, it emits steady sound signal when passing something in the wall. the sound “vibrates” when an electric current has been detected, how does it do that? magic i say, but it works! that’s the main message here.
The Bosch Truvo was very helpful in identifying low risk areas when I had to drill 9 holes in one wall of new-build flat. I removed a wall power socket first to see the wall construction and found it was double-layered plasterboard 30mm thick screwed to metal vertical studs. The detector found the studs and the power cables accurately every time. No water pipes were encountered.
Nonetheless it is prudent to drill with great caution. I started with a blunt slim masonry drill bit and only drilled just to the depth of the plasterboards before pushing through with a cross-head screwdriver which will not damage any pipes or wiring. Then poke around with a long screwdriver to be sure the hollow space is clear before making the fixing.
My plasterboard was not metal foil backed. I suspect the detector would have had a lot more trouble giving clear indications if this had been the case. There are far more expensive “pro’ model detectors for the more difficult jobs but this Truvo is very good value and works well for 30. A useful addition to the toolbox.
Good produc
Very good product. I think the negative reviews are from people who aren’t earthing the wall with their other hand to give accurate readings.
£43 at screwfix!!!
How very annoying, I bought one last month for 43, now it’s on offer at Amazon for 25.
I’ve managed without for years, so the law of averages indicated I was about due a disaster. On the initial pass the unit is oversensitive, but if you pass and repass the area it narrows the area down to a much smaller area, just like it says it will.., in the INSTRUCTIONS.
Remember that the machine will detect nails in stud walls, but such ‘false’ readings can be eliminated by searching above/below and side to side, cables and pipes don’t appear from nowhere.

The detector was easy to use and did the intended jobs accurately.

This one works great. extra peace of mind.
Many thanks to the seller for fast delivery
Just works
Big fan of Bosch tools and not disappointed with this one. Easy to use and very effective. Recommended
Confidence prior to using drill
Was used to drill walls to hang pictures. Had to replace batteries as the ones with detector were faulty.
Easy to Use
Easy to use and did exactly what it was needed for.
Arrived in good time
Had expected this to find studs in timber framed house!
Great produc
Does as it says. Good at detecting various materials such as pipes, wires etc.
DIY novice
I am a DIY novice but this Bosch is better at detecting electrical wires than thr Draper brand I brought and returned. My only concern is that it detects electrical wires as metal even though there is current going through the wires.

Superb
Accurate and easy to use. However it was supplied without a case/pouch.
Detecto
Works well, good for Electric cables , although most heating pipes are plastic which this will not detec
Better than expected.
Several reviews stating that this was too sensitive didn’t put me off. Once I figured out that holding it a few centimetres away from the wall and tested around the known areas it was used on a unknown wall with brilliant results. I found a hidden return cable straight away..that saved me and my wallet.
Works great.
Needed to drill some holes on a wall that I knew had pipes and wires. Bought this and it allowed me to drill with confidence.
Very Reliable
I went for this as the cheap detectors from Argos and Wilko could have killed me. This is easy to use and 100% reliable.
Four Stars
Does get confused with some materials, but still a solid item.
Very accurate device- works perfectly. If you are searching for live cables you MUST put one hand flat on the wall- failure to do so and you will get inaccurate or constant false readings everywhere. Knocks spots of my old Rapitest detector about 15 years old. I marked a wall out on the basis of readings from this device- having removed large sections of plaster the marks were spot on. Highly recommended
Going off some of the negative reviews for this product, I was skeptical about buying and having to rely on this contraption to accurately locate live wires behind the wallpapers/walls. Fortunately for us, due to having had a complete electrical rewire over the entire house recently, which has of course left all the old wallpaper torn to shreds, we know where the electrical wires are simply by looking at the bare plaster walls. This meant we were able to trial this product and discover with no small degree of confidence whether or not this product produced accurate readings. A short test in different areas of the house where we know there to be wires demonstrated to us that this product was indeed very accurate, if perhaps slightly over-sensitive. Though surely, better to be over-sensitive than under-sensitive in this regard. However, one way to alter the sensitivity would appear to be by holding the detector an inch or two away from the wall instead of directly over it. Upon trying this in the same areas as before, the detector still gave accurate readings but didn’t seem quite as hyper-sensitive in its response. The reasons I bought this device is because since our rewire, the living room has since had a full makeover and as such, I’ve forgotten precisely where the wires are running along the walls, in areas which I plan on drilling into in the near future. Better to be safe, sure, than sorry. As I said, judging from the accurate responses garnered from the preliminary trial runs throughout the house, I feel that the device will not let us down when it comes to the real thing. If it does let us down, I’ll be back to amend this review and score, assuming I live to tell the tale.
Great tool.
Bought for my brother who has just moved into a new flat.
Did Exactly What It Should
Did the job I wanted accurately and repeatedly. Can’t ask for more
Detecto
good unit takes some time to get understand its workings compared to my old uni
Works really well! It is quite sensitive and shows red when not directly over wires / pipes but I’d much rather that than the other way around! I’ve tested it a bit and it has shown red everywhere that I’ve known to be a bad place to drill.
This is probably not the best detector out there but for DIY it works really well and compared to my previous pipe detectors (the really cheap ones that have a handle and flat base) this is miles better. Would recommend!

Does The Job
It seems to detect things well, read some of the bad reviews, but as far as I can see it is better than not having it. Does the Job
Certainly not a bad product, but far from perfect. I do find it alerts one minute then not the next so requires testing a few times to make sure calibration is successful.
For the price I’m not complaining, but i’m sure a more expensive one would do a better job.

Simple way to avoid expensive accidents. Bought one after I nearly drilled through power cable. Recommended 🙂
Well i’m still alive...
This seems to work – gives a few false positives but i’ve used it to check the walls before drilling several holes and so far I haven’t blown myself up. It’s fairly simple to use (though the instructions are not as user friendly as one might hope), giving a different response depending on whether it detects metal or a live wire. If you’re going to be drilling regularly, this is probably essential.
Very good product t is this
Going to ve a life saver I am sure. SO easy to use.
Good Make
Easy and safe to use. Reliable results make locating wires and pipes hidden in walls safe.
Promp delivery, excellent service and very useful product. Thank you!
Prompt delivery, excellent service. Previously baffled as to why toilet cistern in new house wasn’t tethered to the wall, then realised that ceiling extractor fan is directly above toilet. That has been corrected, as the Bosch Digital Multi Detector eliminated any fears of drilling into the wall the previous owner had.
Tool for safety first!!!
Seems to me to be accurate for its purposes. Can sometime beep for no reason but I did find that checking and checking again resulted in it being more than accurate enough to let me know where/where not to drill. An item that will last in your tool box for years and may save you some future heartache!!
quite a good product… I used it to put some shelves up in my kitchen and I didnt drill through any wires so it worked fine for me… when placed over live wires it flashes red and beeps fast… when placed over metal it does a long bleep and when there’s nothing there it stays green… 5 stars
Very good. Does what it says and is very reliable.

It works well though is not 100% precise. It it flashes red they is definitely either metal or cabling behind the wall. Drill cautiously if amber or red
I have had a few different detectors over the years and this one was the most accurate.
Five Stars
Does what it says on the tin!! No negative comments.
This has taken all the fun out of DIY. No longer do I plunge the drill into a piece of wall, curious as to whether a cable or pipe lies in wait.
It lights up and makes a range of noises depending on the nature of the hidden threat and, so far, I can’t fault it.
Some people have complained about the Detectors accuracy or usefulness. I beg to differ. It does exactly what it is supposed to do. Indicate where there is the possibility of electrical wiring, metal or other material. I do not expect it to have x-ray vision. It simply indicates where something might be located and then you proceed accordingly. Very useful.
Cable finder.
I have used this tool for a few weeks and it has worked well and does what it states on the packaging.
WOW! I have another brand detector and it was not realiable, this was works well and it’s very easy to use! I jsut recommend to check the batteries
Perfect for beginners
Brilliant piece of kit…nothing special for die hard users but for beginners this is perfect.
I’ve had to purchase this item for use in Spain and found it invaluable.
The electrics are an uncertainty and where they lay them into the walls are not to U.K. standards. So far it has been very useful and reliable.
Good Detecto
Excellent device pinpoints materials below surface very accurately, I have had a few of these devices over the years but this is definitely the best so far.

Five Stars
good piece of kit, does what it says easy to use.
Worth its weight in gold!
This actually works! I was a bit dubious of paying 40 when you can buy some cheaper (they don’t work trust me). It syncs itself basically when it beeps you keep going over the same place and it gets more accurate. Definately buy one! Imagine how much it would cost to call a plumber, plasterer and buy wallpaper just because you went through a pipe trying to save 40 quid
Solid detector - recommended
As good as any detector I’ve used. Gives the odd false reading here and there but generally reliable. My advice is to try it on a live switch or somewhere you know there’s a cable first. I’ve not come across a detector that doesn’t throw false readings sometimes and this one is built to last so gets a thumbs up from me.
Five Stars
Very easy to use and accurate detector. I can only recommend this product.
it's very very good! Firs
I bought this from another retailer since it was slightly cheaper, but have to say, it’s very very good! First, I extracted the device from it’s packaging using my diamond blade circular saw, then I thought i’d test it in areas where I know there are wires. It picks them up perfectly, flashes red and beeps, as you move away it goes amber, then green for all ok.
I had borrowed a friend’s several year old Black and Decker stud finder and still had this when the Bosch unit arrived.
It feels of better build quality than the other make – especially the large “on” button and it feels pleasant to use and sturdily constructed.
In use, however, it did not seem quite as accurate as I had hoped and I found myself trying to repeatedly “zero in” on pipes that I expected it to locate immediately.
It did prove reliable in finding them, however, and this coupled with the great build quality mean that it I would recommend it.
Easy to use, very sensitive
The Bosch Truvo is incredibly easy to use – just switch it on and hold it against the wall. The light goes from green to yellow to red, with an accompanying tone, the closer it gets to detecting metal. When it detects a live electrical source, the red light also flashes.
I tested it directly against the cheaper Bosch PMD-7 – the Truvo is definitely more sensitive. This can actually be slightly annoying, as it beeps even when not particularly close to the source, but it does allow for more accurate and reliable detection.
Well made, easy to use
I have a number of Bosch products and this shows their typical excellent build quality and easy of use. The detector is supplied with 3 AAA batteries, and a simple instruction manual.
The detector has a single on/off switch. Once switched on it self calibrated and then you slide it over the area you want to scan. It responds by changing the display between 4 options,
Green – Nothing found
Amber – Object nearby
Red – Object detected
Flashing red – Live electrical current detected
There are groves in the top and sides of the detector to allow you to mark the spot it has detected and object with a pencil.
I was able to find metal pipes, electrical cables and wooden studs in a stud wall.
Summary – Simple and easy to use detector that actually works.
This is a very easy to use metal detector, with one switch activation it couldn’t be simpler to use than this.
My house was built in the 1960’s so has fairly thick walls when compared to modern houses, this had no problem identifying the pipes in the wall, and on the other side of the wall. It also found all electrical wires.
It works using four display options, Green – Nothing found safe to go, Amber – Something close by, Red – Metal pipe detected, Flashing red – Metal detected with live electrical current
It even found a screw that dropped off the handle on my lawn mower in the grass. As well as this my Mum borrowed it and found the metal backing of a ear ring my niece had lost for her.
Overall very impressive and 5*
Very easy to use and self calibrating
This is typical Bosch; well made and easy to use.
The really neat bit of this is how it calibrates. When switched on, it is very sensitive and will flash / sound when anywhere near hidden metal or electric. Once detected, the sensitivity is turned down and down again as you home in on the hidden item. In practice, this initially allows you to easily find the item and then get a very good / accurate position.
I have tried this on both pipes and mains electric; both work well. In the case of the mains electric, it has enabled me to accurately channel out a hidden wire to safely remove it before some build work took place.
It is not something that you are, typically, going to use everyday, but it does really pay for itself when you need it.
Recommended.
useful
Simple detector.
I think these are great products, it can be hard to know whats best , but this is a brand name I have time for in the field.
Its small and wouldn’t be hard to store, easy to use, and doesn’t have many buttons.
It is designed to detect metal or wood or wires in your walls if you wanted to check before drilling for shelving or picture hanging etc.
It can be so useful, these things are always fiddly to use, but are much better than not using a detector.
Confusing specs.
Worked reliably for me, for known wires. Audible and visual displays, and reasonably rugged casing. Can detect under the surface metals, and will flash red warning on live wires. Easy to use, self calibrating, and takes 3xAAA batteries (supplied).
One problem, is the confusion over detection depths. I have the Truvo, and the box and manual states: Ferrous to a depth of 70mm, non-ferrous to 60mm, and live wires to 50mm. However this contradicts what is displayed on the specs on the Amazon page, the Truvo matches the specs for the PMD 7. So I have no idea how the PMD 7 performs….. How very confusing…..
This is a handheld device which detects metal pipes and wires. It is intended to be used prior to drilling a hole in a wall. As someone who once had to call out an electrician on a Bank Holiday after drilling a hole through an electrical cable, I know only too well the benefit of this gadget. It’s easy to use, you just turn it on a wave it in front of the area you are thinking of drilling in. If there’s any metal there it makes a loud beep. It seemed to beep in all the right places when I tried it around the house. I’d have faith in using this, certainly more than I would do over my own judgement!
Useful!
If you’re into diy, it’s definitely worth owning something like this. Unless you built the place, you’ve no way of knowing where pipes and wires are.
It’s basically a metal detector, which seems to work well-enough, but I must confess I’d still trave roughly where stuff comes from! Plastic pipes could cause doom.
It is a good example of this kind of thing though.
This Bosch Truvo Digital Detector looks remarkably like an earlier model which I own – the Bosch PMD7. The use of a name rather than an easily forgettable numeric nomenclature is welcome though.
This unit is powered by 3 AAA cells which are supplied and easily fitted. The device will alert you using a traffic light system of showing a green LED if there are no detected obstructions, yellow if there’s a metal object in the vicinity of the sensor or a reading is uncertain, red if a metal object is detected in the path of the sensor and if it’s a live wire the LED will flash red. There’s also an audible warning. I found the unit pretty accurate.
The unit is quite well constructed with a large, simple on/off slide switch and rubber edging to the plastic casing. In my opinion the Truvo is a bit large (19.9 x 11.1 x 5.5 cm). It’s annoying that no case is supplied and it’s not easy to find one that will fit because of its awkward dimensions. The instructions are clear but with plenty of caveats which, although they may cover Bosch in terms of liability, they undermine confidence in the unit. Given that the instructions are likely to get lost I think it would be useful to have a basic interpretation of the warning signals printed on the device itself.
Having recently moved into a new home I’m at the stage where I’m putting up shelves and pictures etc. so have used this device a lot. Overall, the unit seems to provide fairly accurate readings. If anything the unit is a bit over eager and tends towards the “skittish” as it gives you a brief warning at first sweep and them seems to settle down – it’s important that you do sweep exactly as it says in the instructions.
Overall, this is an okay device for the money and it delivers its core functionality as claimed but it has to be used properly – the critical issue being the scan technique. I wish Bosch would explain what differentiates this model from the PMD 7 (which is still available in the shops and is cheaper) plus, a brief guide to the warning signals printed on the device would be helpful. Finally, the lack of a case is a pity and is likely to reduce the longevity of the device. On the basis of the cumulative impact of these factors it loses a star but is still a pretty handy tool to have around when putting up pictures etc.
Good Device and Works Effectively
This works very well. I knocked off one star because it feels a bit lightweight and I wonder if it would be easily damaged if dropped. It comes well packaged with the usual blood curdling legal advice and disclaimers that make you wonder why we are even allowed to buy anything these days. Anyway, the instructions are clear enough which as usual people like me don’t read properly first. This device requires three batteries which are supplied and once fitted, that’s it. An on off switch is all you have so why read the instructions? Well, having tried it out near live cables and seen the correct light and beeping, it appeared that my whole house was either full of metal in all the walls or the unit was broken. This may well happen to you too so don’t send the device back. What you need to do, as the instructions make clear, is to touch the wall with your spare hand about 20 cms away from the device to make sure that the earthing is correct and hence, the device operational. This done, the results were as expected.
It seems to do the job as expected and Bosch has a good reputation for reliability so definitely one to consider.
Basically this is a metal detector, so it finds wires and pipes when they are metal, so wont pick up a plastic water pipe which may be what comes into your house from the mains water supply. It’s thicker and longer than a 2-3 year old smart phone, easy to hold in the hand. Powered by 2 AAA batteries. (The little ones).
It simple to use- turn it on and wave close to the wall surface it goes red when it detects metal and if there is a live electric current will beep and flash red. Hard to know just how deep it will detect, but it picked up all around a wall lamp not just above it where we know the cable goes, but was probably also picking up the wall light on the otherside of the wall.
With the copper pipe to the radiators it did pick up the pipes buried in concrete screed through the carpet. However might not be so effective if you have an old property with a big gap between the floor boards and pipes, that said DIY might only be a problem if using a long drill bit or using long nails.
Will be very useful also when pins, needles, earrings get dropped on the carpet, or keys in the garden, as long as you have a rough idea where they might be or a lot of time to spend on your hands and knees.
Well recommended for a DIY enthusiast to avoid drilling into electric cables or putting a nail through a water pipe.
Basic but useful
The Bosch Truvo digital detector is a fairly basic machine all of the feedback is provided by a tri-coloured LED and a beeper, it is light enough to be used single handily and is comfortable to hold. There is only a single switch to turn it on and that is it, there is no hole to drill through or use with a pencil like there is on other detectors but it does seem to be pretty accurate. It is possible to tell the difference between metal objects and live wires but not between ferrous and no ferrous metals.
Unfortunately it cannot be used to find wooden studs in walls but it does appear to have some kind of learning abilities, when you detect a metal object in a wall if you keep sweeping the device over the area without lifting it off the wall it appears to get a much more accurate reading.
