[@ladyrakoon6851]

Thank you for the review! Loved the format. Quick and simple, easy to understand but still very comprehensive! Thanks a lot!

[@bfscho]

I've had two of these. The first one thought everything was metal, including a house plant leaf 🤦‍♂️ the second didn't pick up something metal yesterday and luckily that only wrecked a drill bit and no other damage was done. Calibration is very important!

[@NoisyBadAss]

Far the best review of this product. Ordered it based on this, so thank you for the uploading.

Thanks for the video! If I want to drill on a stud exactly, do you have a tip?

[@shanecollier7952]

Excellent video and info. Simple, clear and a nice little item. Many thanks.

[@murmansk69]

Not sure the test is all that convincing as you just held the detector in the air and approached the cables and pipes as you knew where they were. In real use you'd move the thing across the wall and wait til you hear a bleep. Also, you didn't show it being used on a solid wall which I think might give a different result?

[@DoItAllDan]

The position of the material would be irrelevant as your testing through the wall, knowing where it is or not wouldn't apply.... If it was tested on a solid wall the results would be the same as stated it detects certain depths into different surfaces.

[@JamieSarai]

Do It All Dan but your test doesn’t show that it goes green on the surface between the obstructions, moving across the wall.

[@DoItAllDan]

Jamie Sarai it wouldn't as the objects would be too close as you can see they are only a few inch apart, this is to give you an idea that there is something in the area you wish to drill. It's not recommended as it states to be exact as some models on the market, it £30 so I wouldn't expect miracles to be honest 👌🏻

[@s-1320]

Should have slid it slowly sideways so we could see how accurate it was.

[@DoItAllDan]

It’s not meant to be 100% accurate and you should never rely on one

How deep this Bosch can catch metal in wall?

[@alejandroastorga653]

Would it work well on a solid wall? House built 1950

[@lsamoa]

I have one and I'm not convinced by what it's telling me. I'll scan a wall area and have it all green, but then I'll stay still somewhere and after a couple seconds it will flash red as if there's a live wire there. Try again: green. I can't figure out if it's giving me false positives or if it's is bad at systematically detecting wires.

[@DjGiluk]

Great vid thanks

[@borisi6342]

Today I tried it I have one question - when I hold the device at the black rubber bottom side areas as written tn the manual it blinks for live wire detection a lot frequently even in not logical palces. When I hold it a little bit upperon the green coloured side places it detects only when I am more convincet there is a live wire because it is at the top of the switch for example. Can you tell my why this is happening and am I right?

[@RobertLuciani]

I find that I get a lot of false positives with this. I put up a small wall in my pantry with no wires behind it. I tiled over it and needed to find the studs to hang a shelf. Didn't detect the studs and it beeped for live wires. I am not happy with this thing.

[@arshtruth3649]

Very good review!

[@treewat3685]

How do you know whether the metal should stop you drilling? I'ts picking up metal everywhere, but it picks it up to a depth of 7cm and I don't need to drill that far into the wall to put some shelves up, but I can't tell if the metal is right near the surface of the plasterboard or like you say just nails in the stud

[@DoItAllDan]

If you wanted more precise readings I'm afraid you will need a better detector that can differentiate between metals. This is a basic/simple detector, I have to emphasize just make sure your not on any cables/pipework before drilling.

[@robwicke1709]

Thanks for this Dan. Am I right in thinking you held it slightly away from the surface rather than flush to it?

[@DoItAllDan]

I would hold it ever so slightly off just so it doesn't get confused or caught on something

[@alexishw]

Plasterboard is easy does it work with pipes in brick/plaster wall in older property?

[@DoItAllDan]

It does work but only to a certain depth I still use this now ✌🏻

[@DoItAllDan]

Unless lined with metal no I'm afraid

[@Southpoint2019]

@@DoItAllDan when you say lined? Wall ties are mild steel

[@Vizzo69s]

Any advice if I go over the same area and get different results? Sometimes it suggests live wire (flashing red), other times it then shows green. Very unreliable and therefore unsafe from what I've seen so far.

[@DoItAllDan]

This picks up a variety of materials just be cautious in where you are scanning 👍🏻

[@alastairdudley1084]

There is an issue with this gadget contradicting itself depending on which direction you move it. So (for instance) move L->R it’ll go green, red (mark it) and then green. Reverse over the same area and it’s green all the way. Or red. Now add another variable. Touching the (brick) wall with my free hand, I can often change the green to red or vice versa. The project I’m doing is taking ages because it is unreliable, but still better than nothing. I’ve changed batteries and become a dab hand at recalibrating btw.

[@RileyNickers]

I am encountering the same issue and it is a new unit that has been calibrated. I'm also wearing shoes that earth me so i am at a loss why placing my free hand on the same surface affects the result.

[@johngodwin4586]

Does the performance of this device get adversely effected by ceramic tiles, i.e bathroom etc ?

[@DoItAllDan]

There will be many factors to consider from materials and what they may contain to any rogue nails etc so I would advise to use with caution and a little common sense 😁👍🏻

[@adamsala9291]

How about wood

[@annabellewallis291]

Is it safe to say that whatever pipes and wires are behind they'll almost always be vertical?

[@DoItAllDan]

No, I can pretty much guarantee they will pretty much never run vertical. Most of the time they aren't clipped or supported in position so don't take it for granted be cautious Annabelle 💪🏻👍🏻

[@andraskurucz2129]

It looks easy to find metal behind the plasterboard but is this find the pipes under the 18mm floor boards or if the pipe goes through the joist?

[@DoItAllDan]

I wouldn't want to guarantee it I have never tried that I'm afraid.

[@TheJessefarrell]

Good review, however I'm trying to use it as a stud detector. Mine seems to go yellow whenever it detects timber - is that correct?

[@DoItAllDan]

It will be picking up the lining, screws or support struts it's only a metal detector I'm afraid and won't pick up anything other. Hope this helps

[@marcdee4427]

How do you know if it needs calibration, and is the automatic calibration just as good

[@DoItAllDan]

Always test before use 👍🏻

[@marcdee4427]

@@DoItAllDan , thanks 😊 but what’s the automatic calibration for then ?

[@DoItAllDan]

After a period of time, it becomes unreliable as does with all auto cal product, so always best to get it re calibrated down the line 👍🏻

[@marcdee4427]

@@DoItAllDan I’ve just bought it today, so it should be ok straight from the box I’m sure . But is the only way to tell that it needs to be calibrated, is when it’s held in the air with no metal near , it should be green to be ok , if it’s flashing yellow and red it needs calibration

[@tasty_fish]

Like many I’ve used detectors that seem to think the whole wall is live. What I’ve found is that how I hold them tends to affect the detection, almost as if my body is somehow acting as a conductor. So I have to adjust my grip. Others seem to detect solid brick/blockwork behind plaster so it would’ve been good to see how this one works when it comes across solid objects behind the plaster as these seem to give false positive readings. The TH250 (sold under various brand names on Amazon and seemingly made in the same Chinese factory) is particularly crap. If this Bosch one works then the TH250 is getting smashed up with a hammer!

[@tasty_fish]

So now I’m in possession of this Bosch detector I’ve found my fingers are really conducting something as every time I touch with both fingers it buzzes. I’ve got round this by holding the scanner against the wall in its plastic packaging with no interference from my electrically-charged body! Seems to be accurate then!

[@zahidb4608]

Agreed. I feel like there is other detection than from the wall. Yet to find a proper key of all the flashes and beeps explanations. That would be a real review.

[@no4h1453]

For me, it looks like touching the wall with my other hand gives more accurate results. It could be static electric charge, earthing or wearing a watch which might affect the detector

[@karlpopewoodcraft]

Another great review Dan I will be purchasing one of these as I do quite a few shelves and my stanley version is playing up.

[@neroxxx]

Will the Detector detect wires in a block wall? rather than plaster board?

[@bazzab44]

Thank you for the review Dan. I’m considering purchasing this to check pipes/wires under floorboards. I’m looking to secure some that are causing squeaking before having new carpet laid. Assume this would equally pick up and pipes and wires under floorboards? Are pipes under floorboards outside the 70mm zone of detection? any help much appreciated.

[@DoItAllDan]

It would depend I'm afraid if it's a suspended floor the pipework could be laid anyhow it really does depend who has done in install thanks

[@SuperEmogirl1995]

Can you use it on brick wall?

[@DoItAllDan]

Yes👍🏻

[@RocketMagnetUK]

Under normal use case for home gamers (Target Market Green) then this device can be very poor as it gives constant false positives... much better than false negatives but this seriously limits the tools reliability. I've tested and confirmed it picks up various WiFi and RF signals as live cable. Placed the device on a wall near my door bell receiver (about 1m away) and it gives a live wire result... shield the wireless device with my hand and it turns green and back to live when I stop shielding with my hand. So here the wireless signal is proven to cause false positives... so my tip would be to turn wireless devices off in the vicinity. So my takeaway is that in a modern home there is so much interference that their use is very limited.. my entire adjoining wall to next door is apparently "live" and my wooden door apparently has live cable embedded in it. So yes I agree in certain cases this device can be useful but for most people in homes with all the modern devices its use is limited IME.

[@DoItAllDan]

Thanks rocket, to be honest I've never had an issue with its use and accuracy. 👍🏻 Thanks mate

[@leewilliams955]

[@jobailey8112]

I bought one of these 6 months ago. It's been great. Tried to use it today, wen I'm passing it over the wall it'll flash red over an area, but when I then stop moving it, it turns solid green over the same area where it was flashing red. New batteries and I've recalibrated it. Please help! 😲

[@DoItAllDan]

It does sound a bit off, but remember that it will pick up not only the target but the local area, so it could just be picking something up close by. The only thing I would suggest is if you're unsure do not use that location you can move a few inches around to get a better placement

[@JamieSarai]

The problem I have with this product is that it flashes red as though there is a live cable MILES away from where I know is.

Hi Jamie, to be honest while using it I've found it pretty accurate. There is a little disruption il admit especially if there are tacks or screws below the surface. Have you found another one that you might recommend I may give it a try? Thanks

[@JamieSarai]

Do It All Dan maybe mine is faulty... I’ll see if I can get a replacement.
