It scans metal, but can not distinguish between timber, metal and AC wire! plus the AC mode does not detect anything. I bought it a few days ago!!

Unfortunately Bosch made a lot of defective GMS120s. They are very good at exchanging them though.

I've had the same problem with mine, I bought mine couple years ago, I've stopped using after couple of projects.....

That's true: it can't distigush between AC, wood or just metal. You have to aproximate/figure out the lay out of them. Other thsn that, it's prety precise finding the wood studs. Good luck! C-tin.

Well I'm not sure if that is question or a statement. Yes there are big issues with this scanner, one of which is the inability to distinguish between wood and metal in the wood scanning mode. You can get around this by using the metal mode which will only detect metal and AC. Its been a while since I returned this item so I'm going by memory, but as I recall there is a little lightning bolt that appears when it detects AC. Read my review of this product. It will tell you all you need to know.

This unit is touchy...but it will detect wood, metal and electrical. It is vital to calibrate it each time before you try the actual scan I place the unit against the wall and my other hand on the same wall this helps to calibrate it. After it settles you can start your scan.

Personally I did not find it capable of detecting frequencies in the MHz itself let alone GHz range of wifi. It is best for detecting ELF such as power lines and microwaves, but that's about it.

It can detect a small staple in a piece of 1x6 lumber. I can't speak to your exact use case, but I wouldn't bet my life on it. The item is very sensitive, though... you might just buy one and test; send it back if it doesn't do what you want.

The scanner has the ability to be powered in more ways than one. I can only assume at the moment that you rely on the power directly from the connection to the car via the cable and plug in adapter. Have you tried to power it using the Power Adapter supplied with the scanner? Give it a try if you have not already. Obviously, if it still does not work you will need to contact the supplier and return it for an exchange.

It's not made for that so I don't know how sensitive the readings would be, but I do think it would give some response. It has two small metal prongs that you stick on or in different materials and then it beeps and shows a percentage read out. You can switch it from "wood" to "building materials" depending on what you need to test. I did use it on some foam that the builder sprayed into a crevice, and on some rotted drywall that was spongy.

If I had to guess, I'd say that it's not ready to find a stud because it's being placed on the wall at a place that is interfering with it's operation. Usually you would place the scanner on the wall at a place where you know there is no stud and then start moving it towards where you believe there should be a stud. It should not be beeping and flashing all the time. It should only do this when it approaches and then finds a stud. If you can't make it work, it may simply be a bad unit. Keep in mind, I am only guessing from the information given.

The scanner scans conventional frequencies and trunk systems. This one is called...triple trunking mobile/base radio scanner.Mine receives all the channels that I need for the areas I have used it. I assume it is analog.....but the only digital is the display..

Hello, I have no idea, was just curious about the item and thought I could use it to possibly track down a wall switch that goes nowhere in our house. turn off all breakers but the circuit the switch is on and check for a signal thru the wall with the switch on and follow it, have not tried yet. Just checked around a few wires and it does sense the electricity. I think the deal on it detecting cameras is that you can see the infrared with it or something. Have not had time to really check, it may just be a barely useful gimmick. But I hope I can trace the wire. It may make a cool kinda selective sensitivity signal tracer.Peace!

I am not sure that this is the same scanner that I purchased. The zircon scanner that I have has been used a lot to search out hidden nails in old timber beams and works reasonably well to a depth of apprx 2-1/2". Finding shot in a duck w/a scanner like or similar to mine should be a lot easier than timber. I would be interested to hear if Nicholas purchases the scanner and his results. good luck & MERRY CHRISTMAS.

Got this for Xmas Yesterday to measure speaker ohm's. it say to shot the two prongs together to read 0... Not on mine, its says 1.1-1.3, So to me, its junk because i need to it measure 4ohm's and below. its going back!

I wish I could help but I gave it to my grandchildren at Christmas and it wont scan things. I tried to get it replaced but no one was willing to help me so they still have a gift that wont work. Hope you have better luck than I had.

Not really. Its not designed to do so. It may but there is no way to tell if it is wiring or something else. The instructions give a warning that what it detects could be a stud, pipe, wire or other objects

No - it measures wire length (in feet or meters only) according to the gauge of the wire - copper or aluminumAccuracy is pretty good

Well.., this scanner can detect all metals, behind ceramic too, but sometimes make mistakes. Only in metal mode can use to that work.

HI! it only makes a sound over metal! =-) It is a really great little detector. In time my son (12 years ole and brilliant) LOL does want a more professional one that will actually filter out junk from the good stuff . Those are a few hundred dollars so that will be when he is much older. For now he LOVES this thing and when we bring it to the playground or beach he has a ton of little followers that are intrigued beyond belief. SO far my son has found an old belt buckle (1800's) old medicine bottle (again (1800's era) tons of coins. =-)

No. This will only measure electric fields in a specified frequency range. It will not measure gauss and not permanent magnets as their field is essentially a 0 Hz signal, which is out of band for this meter.This meter works but you have to know how to use it and know what you are trying to measure. It is also sensitive to false readings, like tapping it with your finger or static electricity. If you think you are getting a signal, stop moving around to make sure it isn't you generating an inadvertent static electric field. FYI, a static zap is an impulse signal and contains frequencies from DC to daylight, so yes, this meter will freak out a bit.

Simply yes it does. How do I know this. I was curious as well. And tried my scanner on everything. I hope this was helpful. One more thing it can also be used to find studs behind walls and hidden wires and bullets in dirty diapers.
