Your cart is empty.The Zircon MetalliScanner m40 electronic metal scanner quickly and easily detects metal in lath and plaster, wood, drywall, paneling, tile, stucco, plaster, concrete and other non-metallic surfaces. This metal detector locates ferrous (magnetic) metal up to 4 inches (100 mm) deep and non-ferrous (non-magnetic) metal up to 2 inches (50 mm) deep. The Zircon m40 has two scanning positions, Wide Scan and Pinpoint Scan. To get started, install the included 9V alkaline battery. Hold the tool in the air away from any metal but make sure the blue sensor is parallel to the surface being scanned. Press and hold the Power Button to calibrate the unit. Once you hear a beep and see the green "Ready" LED illuminated, calibration is complete. Continue to hold the Power Button as you slowly slide the tool across the surface. As the MetalliScanner approaches a metal object, the red LEDs progressively light from the bottom up in both scanning modes. The top lighted blue coil and an audio tone indicate when a metal target is located. This MetalliScanner m40 tool easily solves the very difficult problem of finding studs in lath and plaster walls. It works as a nail finder by detecting the pattern of nails that attach the wood lath to the studs. Additionally, the MetalliScanner m40 metal locator finds plumbing, ductwork, rebar, nails and screws in your walls, floors and ceilings and is great for scanning reclaimed lumber for hidden metal. Now in easy open packaging, this product comes with everything you need to get started, including the battery! Backed by our world class customer service and support, we at Zircon know that whether you're a Construction Professional or weekend DIY enthusiast, you'll find the m40 has the technology and durability you're looking for to get the job done right.

I use my Zircon hand-held metal detector to check recycled/salvaged lumber for nails. It works perfectly for my needs.I have also used it a couple of times to find some small pieces of steel hardware that I dropped in the grass. I don't know why they don't sell these in the store. A is really a great little tool!

I was at a loss how to locate a stud under lathe and plaster. My infrared stud finder could not penetrate this material. Did some research and found this neat way to find a stud in this situation; use an electronic metal detector to find the nails which fasten the lathe to the stud . Mark the location of each nail, connect the marks, and you have a line which shows the location of the stud. Brilliant low tech idea! Bought this low cost metal detector and located the stud right away. Finds nail heads up to 13 cm below the surface. No need to rely on tapping or peppering the wall with exploratory drill holes. Highly recommend.

My home was built in the 50’s and all the walls are plaster, so a typical stud finder doesn’t work well. This however works great! I’ve tried a ton of different stud finders and they’ve all failed until I got this one. The pinpoint feature is really nice to so I can make sure. Don’t screw into a nail! If you have plaster walls like I do, don’t hesitate getting this stud finder!!

Worked as designed, once in a row, not enough test to judge reliability or sensitivitybut doing well so far, plus, looks rather cool design-wise

I needed to install grab bars in a bath tub. This metal scanner located studs and nails behind a tile wall. The results were reproducible and reliable; whereas the results from a traditional stud finder were not. Took a few tries to find a good place on the wall to calibrate the instrument each time I did a sweep. Once I did, it went pretty quick. Used a dry erase pen to mark the edges of the studs and then mark nail heads. My friend who drilled the pilot holes was impressed. Nailed those studs! Worth every penny.

I have quite a few stud finders that can also seek metal and AC wires and do deep scans, including several Zircon models. All work OK, none work well enough to really rely on them. I was particularly looking for something that can find nails and screws, rather than metal pipes and metal drywall corners. This one purports to find nails, but I have tried it out repeatedly on places where I know there are screws or nails that I can see. This unit misses three fourths of them, even when the heads of drywall screws are at the surface, but it squeals red alert when it passes over taped drywall joints where the mud is thicker. I would say this unit was batting about 5% on visible finishing nails or drywall screws. I am OK with a false alarm once in a while, but failing to find ferrous nails and screws makes it useless.

First, the unit received looked like an Amazon Warehouse deal, repackaged return. Second it really had a hard time picking up the studs, metal. Returned it

I have an old house where the lathe & plaster walls do not work with standard stud detectors.It has a few different modes where you have to do a more broad scan first and then 0 in on where the metal is but it actually works and much faster than using a small rare earth magnet or something like that.

Me ha servido para localizar varillas en muro, por si agujeras un castillo y no vaya a interferir al hacer algún agujero para cortinas u alguna otra cosa.

Keeps beeping on the entire wall surface; not accurate and does not tell you where to drill or not to drill

This is a good device for detecting nails in pallets when they have been pulled apart. It is also handy to check out demolition timbers.

This is a relatively inexpensive scanner; when I first tried to use us it to locate rebar, I discovered why it is inexpensive: it is very imprecise....I always required many many passes of scanner to gain confidence that I had actually located the rebar....constantly required recalibration. Quite frustrating.
