    • This easy-to-use stud/metal/wire finder is great

I use it for the thick drywall/plaster or wood floors in my house and works much better than the cheaper electronic ones I have used in the past. Most of my 1950s home's walls have drywall coated in plaster and are about 1" thick is most spots so non-electronic and electronic stud finders never worked too well. Remodeled areas of my home also have the standard 5/8" or 1/2" thick drywall and 3/4" thick wood paneling which I use this mostly successfully on. I also used this successfully to detect flood joists beneath wood flooring, copper and galvanized pipes behind cement board/tile and to find rebar in cement. It can detect steel as deep as 4.75" in the wall, wood up to 1.5" and wires up to 2". Using it around the house, I find it works better in the thick walls and wood paneling, especially for finding live wires. In the standard thickness drywalled walls, it does not find electrical wires well but it does find studs and plumbing well. The only downside to this detector is I cannot get it to consistently find electric wires behind 1/2" or 5/8" drywall which is standard on most homes. In most cases, it will not detect them at all but does give a reading sometimes. This is probably due to the finder only being able to detect wires up to 2" deep in the wall. Sometimes wires are not within 2" of the drywall surface. It also cannot detect studs well behind wood paneling which is not surprising. I find it pretty user-friendly, just turn it on, set your mode (wood, metal, electrical) then place it on the wall and give it a second to calibrate. Afterwards, start searching. It will alert you to whatever mode you have it set on with a bar gauge. When you have it on wood mode, it will also alert you to metal and wires which is convenient. It makes noises as you get closer (you can turn the sound off, it is a bit irritating). When you find the center of a stud, pipe or wire, the finder has a convenient holes you can stick a pencil through the mark it. It seems to find wood with the assistance of finding screws/nails and overall, I find its best to scan up and down to find the exact position of the stud, pipe or wire. You probably wont get the exact location on the first bullseye. The finder also has a backlight for the screen when using in dark areas. The finder comes with a 9v battery, carrying case and directions as well. The directions take a little reading. Overall, this is great for finding studs and pipes but 4/5 stars for the general inability to find electrical behind standard thickness drywall. 5 stars for versatility and ease of use. I thought about knocking it down a star for general failure to detect wiring but its scan range for wiring is limited as stated. ... show more

    • Reliable and Accurate—Finally a Stud Finder That Works
Style: Industrial
I’ve tried a few budget stud finders in the $20–40 range, and most were unreliable—one didn’t work at all. This one, however, is flawless. It comes with 2 AA batteries, so it’s ready to go right out of the box. It immediately located studs with an audible tone, and also detects wires and metal. I especially love the built-in marking hole in the center—it makes it easy to pencil your spot without guessing. Excellent tool and well worth the price. ... show more

    • Nice Scanner, "OK" Stud Finder
Style: 9V Battery
I gave the Bosch scanner 4 stars because it does work decent for the most part depending on where I am in my home. But I think I would have given it 2 or 3 if I was reviewing it on only finding studs - especially in my garage where I know almost exactly where many of them are already and it is off enough to make you possibly miss the stud if you were going off its reading. I think I have more stud finders than just about anyone and they all have their pro's and cons and "sorta" work depending on the application. I guess I am just determined to find one that works for all applications and it seems some come close (like this one) and others are plain crap. Honestly the last one I bought before this (can't remember the name but it's sold on Amazon) was basically a set of 4 yellow plastic covered magnets and they work perfectly at finding the studs - how funny (but obvious) is that? That set was something like $5 - $10 I think and it blows away most all electronic models I have when doing the basic task of locating studs. I have watched several reviews of this scanner and it seems to work well with the various types of scanning it can do although I cannot comment on those as I have yet to try them in an actual situation other than scanning areas I know have power going to them for example and it does recognize there is power behind the wall in that area. ... show more

    • Good scanner, but fiddly
Style: 9V Battery
I bought this because of the great ratings and reviews here and elsewhere. But I found this tool very fiddly. It has problems with our walls and find electricity and studs where they are not. I have had much more better luck with a cheap stud finder. However, when this tool does read properly, it is very handy, because the target is perfect for centering a mark. Perhaps our walls just have some weird stuff behind them (and it wouldn’t surprise me after what we have seen. ... show more
