Trying to determine the best use of your tool and not sure who or how to ask? After many decades of experience in working with pro users, I’ve consolidated some common FAQ’s that should help pros and DIYers alike get the most from their stud finder. These troubleshooting tips are designed to save you time, money, and headaches.

Top 5 Stud Finder Troubleshooting Tips

1) Check Your Battery. If your stud finder worked previously, but no longer seems to work, about 9 times out of 10, the problem is a weak battery. You may swear that the battery is still good, but it’s not.  Is the battery new from the store or new from the drawer?  Many people don’t realize batteries are no longer functional after their expiration date, even if they have never been used and that 9V batteries do not hold their charge as well as other battery types.

Each of these batteries has a printed expiration date, but they are all in different locations on the battery.

Each of these batteries has a printed expiration date, but they are all in different locations on the battery.

Many batteries have an expiration date printed on them; however, those dates are often an estimate, as batteries can often wear out earlier due to extreme hot or cold. One recent customer insisted his battery was good because the battery could still open his garage door, and “those garage doors are heavy!” Haha. Compared to garage doors and many other devices, stud finders require a very strong battery. When customers realize that the battery really is the problem, they are usually relieved that it was such a simple solution, and that their stud finder still works! You can find more battery tips by visiting the Zircon in the Real World blog, How is Your Battery?

2) Place First, then Scan. Put the tool up against the wall first, then press and hold the button to start scanning. Stud finders work by measuring the density behind the wall. The density over the stud is greater than the area away from the stud. Your stud finder automatically calibrates to your wall as soon as you turn it on.  If you mistakenly press the calibration button before the stud finder is placed on the wall, the stud finder will calibrate to the density of thin air instead of calibrating to your wall.

The Zircon® MultiScanner® i520 is an example of a center finding tool.

3) Are You on the Edge or on the Center? Determine if your stud finder is an ‘edge finder’ or a ‘center finder.’ A Zircon center finder will indicate both edges and the center of the stud. With an edge finder, the user must mark both edges of the stud to determine the center.  A common mistake is for a homeowner to mark only one edge of the stud which often leads to a screw placed at the stud edge and not at the center of the stud.

4)  Is it Drywall or Lath and Plaster? Your stud finder is designed to work with sheet materials like drywall or plywood.  If the wall is lath and plaster or some other material, you’ll need different solutions that you can find on my blog, The Secret to Finding Wood Studs in Lath and Plaster.

5) Mark it. Make sure to mark the stud edge on the wall with a pencil. Although DIYers often carefully locate the stud, they just eyeball where to place the screw. By doing so, they are only approximating where the stud edge actually is located -they miss the stud, and think the stud finder does not work effectively. I recommend using masking or painter’s tape on the wall, so the marks are not permanent. It’s also a good idea to use longer pieces of tape so you can ‘map out’ multiple stud locations in your work area (studs are normally spaced 16” or 24” apart on center).

How to Find Studs through Stucco

I am often asked if it is possible to scan through stucco exterior walls. Contractors, remodelers, and DIYers are often surprised that Zircon does not recommend their tools for outdoor use on surfaces such as stucco. However, we have some tips that may still help you get the job done when you need to locate studs behind a stucco exterior wall.

Why Not Stucco?

Stud finders are designed to scan through sheet materials that have a consistent thickness and density and have a fairly smooth surface. Stucco walls typically have chicken wire, or some other metal mesh, embedded in the stucco and that metal barrier will prevent your stud finder from sensing the increased density necessary to locate the studs.

Real World Example

Al, a general contractor who has served as part of Zircon’s pro user focus groups for 15 years, recently encountered this problem. He had already built several redwood flower boxes and wanted to fasten the boxes to the exterior walls of the green stucco building.

The stucco exterior of this building contains metal mesh that prevents stud finders from working. (You can use a Zircon tool with metal scan mode to determine if there is metal mesh in the stucco).

While Al has been an expert user of Zircon products for many years, he was having difficulty finding the studs through the stucco due to the wire mesh.

Al explained that he wanted to fasten the flower boxes to the exterior walls of a commercial building, but he was having trouble finding the studs through the stucco. I proposed the tips outlined below, which can also work for people who need to install things like awnings, lighting, flag pole brackets, hand rails, or satellite dishes to stucco walls.

Work-Around Solution

The work-around solution is to locate the studs on the interior walls and then carefully measure the distance from the studs to a door or window, and transfer the exact same measurement to the outside of the building.

Locate the studs on an inside wall, and very carefully measure the distance from the studs to a window or door.  Tip: Don’t measure off the window trim.  Measure from the edge of the glass so you know the exact same reference point can be found outside.

Work-around Solution. Step 1. Locate the studs on an inside wall, and very carefully measure the distance from the studs to a window or door. Tip: Don’t measure off the window trim. Measure from the edge of the glass so you know the exact same reference point can be found outside.

Note, do not use the window trim as your reference point. Instead, measure from where you can actually see through the glass, so you know the reference point is the same on the inside as well as the outside of the building. And, of course, you must be very precise with your measurements! Perhaps you’ve heard the saying, “Measure twice, cut once!”

Work around Solution. Step 1. Next go outside and measure the distance from the edge of the glass to the studs behind the stucco exterior wall.  Although somewhat time consuming, many pro users have reported success with this method.  The key is being very careful with the measurements.

This work-around solution can be time consuming, but well worth it and very necessary. Objects fastened to the exterior of the home are often heavy and exposed to wind force, so it is vital that the heavy objects are fastened securely. This method proved to be successful for Al and for many tradesmen that I have met with for several years.

Al needed to locate the studs to securely fasten the planter boxes he built to the stucco walls.  I advised him of the work around solution.

Metal or No Metal?

To determine whether your stucco has metal or not, use a Zircon metal detector, such as the MetalliScanner® m40 or a MultiScanner® i520 in metal scan mode. Some newer construction buildings use a fiberglass product embedded in the stucco, so if there is no metal mesh, you can use the DeepScan® mode in your StudSensor™ or MultiScanner® stud finders. However, if the building has wire mesh in the stucco, then try these work around tips for locating studs behind stucco.

To Scan? Or Not to Scan? That is the Question.

I recently attended a large event for satellite dish installers who asked me for advice and tips on how to use Zircon® StudSensorTM or MultiScanner® stud finders on the roof to locate rafters. They were really surprised to hear that Zircon does not recommend these tools for outdoor use.  I hear the same reaction from solar panel installers.

At this new roof, we don’t see tar paper over the plywood yet because the construction workers are experimenting with a few different shingle patterns.

At this new roof, we don’t see tar paper over the plywood yet because the construction workers are experimenting with a few different shingle patterns.

The reason is that stud finders are designed to scan through sheet materials, such as drywall or plywood that have a fairly smooth surface and consistent thickness and density. A typical asphalt shingle roof has a layer of wood based sheet material, usually plywood or chipboard, and normally with a layer of tar paper.

Then, the asphalt shingles are  fastened to the roof with roofing nails. The difficulty with scanning for rafters is that the asphalt shingles now create an irregular scanning surface that can result in false positives (stud indication when a stud may not actually be present).

On many other irregular surfaces, I recommend switching to metal scan mode and locating screws, but that won’t work on the roof because you are unable to differentiate the screws that fasten the plywood to the rafters from the roofing nails.

Although our newest MultiScanner® x85 OneStep® wall scanner (capable of finding studs, detecting thermal changes, and locating live AC wiring) is also not recommended for outdoor use, it is more technologically advanced in scanning over inconsistent and irregular surfaces.

A MultiScanner® x85 scans through asphalt shingles and plywood and the tool indicates the center of a rafter at Zircon’s Research & Development department. Notice the LCD screen and the SpotLite® pointing system on the shingle.

Hundreds of installers tested the x85 on a section of roofing with asphalt shingles that I had brought and compared it against some of our other stud finders. The response was tremendously positive! Although the x85 sometimes required recalibrating one or two times, the x85 definitely worked much better on irregular surfaces than the other models.

The x85 has advanced technology that improves its performance on irregular surfaces, but keep an eye on Zircon.com for new products actually designed for indoor and outdoor scanning.

For this reason and despite our recommendation, many DIYers and professional contractors still use Zircon stud finders on exterior walls and roofs because they find that they still detect their target some of the time. While Zircon does not encourage these tools for exterior use, here are some tips that may increase the detection of rafters on asphalt shingle roofs (but not tile or wood shake roofs) if you plan to use it anyway.

1.  Place a piece of thin cardboard over the irregular surface and slowly scan over the cardboard.  Start in normal Stud Scan mode The cardboard will enable the tool to more smoothly scan over the area, but it also may work fine without cardboard.

2.  If your tool continuously blinks and beeps, it may be indicating calibration errors or a decrease in density. If this occurs, switch the scan mode to DeepScan® mode. The tool will still indicate increases in density, but it will disregard decreases. Note: you may need to recalibrate in a few different locations.

3.  Don’t assume the first indication of a rafter is correct. Scan the same surface area a few times and make sure the tool consistently indicates the same stud finding results in the same location each time AND also, scan for other rafters that are equally spaced such as the standard 16 in. spacing distance apart from the other rafters.

4.  Gently tap on the roof with your hammer and listen. Tapping over a rafter will often result in a more solid sound. Although it is difficult to pinpoint the rafter this way, it can help boost confidence in the location if the hammer results agree with your stud finder, However, remember stud finders are not recommended for outdoor use (although they are used anyway).

We often get asked, why does my stud finder have trouble with lath and plaster when it works perfectly through drywall? Or, what is the best tool or technique for finding studs in lath and plaster walls?

The front of this lath and plaster wall is smooth - no problem for your stud finder.

The front of this lath and plaster wall is smooth – no problem for your stud finder.

Your Zircon stud finder finds studs by looking for an increase in density compared to where it was first calibrated on the wall.  Drywall and other manufactured sheet materials have very consistent density, but lath and plaster walls have very inconsistent density on the backside of the wall. This is where the plaster is squeezed between the lath and ‘keys’ onto the back of the lath and holds the plaster in place.

So, even if the front of the wall has a very smooth texture, the back of the wall is what gives your stud finder trouble because there are changes in density everywhere as you scan.

Shown here is a peek behind the wall. Lath and plaster walls have an irregular surface that are a problem for stud finders.

As a result, your stud finder can show a false positive (a stud indication when it is actually not a stud) when it finds an increase in density, even if it is just a glob of plaster.

The best solution is to use a Zircon MultiScanner® wall scanner that has Metal Scan Mode or one of Zircon’s dedicated metal detectors, such as the MetalliScanner® m40 or MetalliScanner® MT 6, so you can find the little nails or tacks that are fastening every piece of wood lath to the studs.

Use a Zircon metal detector to locate the nails that fasten each piece of lath to the studs.

Use a Zircon metal detector to locate the nails that fasten each piece of lath to the studs.

Since you can detect the nail heads all the way up and down the entire height of the stud with the Metal Scan mode, this is a much more reliable way to find studs.

From time to time, major home improvement stores invite contractor customers to the store to enjoy complimentary coffee, juice, and a breakfast buffet. Select vendors also set up tables to display and demonstrate their latest tools. As I was performing Zircon demonstrations at one of these events, practically every contractor said he already owned at least one Zircon stud finder.  But then two twenty-something year old guys, and one 50ish year old guy who seemed like the boss, and his wife, walked up to the table.

“Missing the stud by just a hair can be a big problem when people hit plumbing or electrical on the side of the stud.”

“Missing the stud by just a hair can be a big problem when people hit plumbing or electrical on the side of the stud.”

One of the guys had just received a Zircon MultiScanner wall scanner for his birthday, but hadn’t used it yet. I took this opportunity to show him how it worked by using the scanner on our demo wall. I then handed him the tool so he could try for himself.  His friend was also interested in the tool and wanted to try it as well. However, when I asked the boss, he said he didn’t need a stud finder. He just knocks on the wall and listens.

Now, the boss seemed like the kind of guy who has more construction knowledge than I’ll ever have. I didn’t want to sound like I was telling him what he should do, so I explained why many people need stud finders.  I rationalized, “Yeah, knocking on the wall can work if you’re really good at it…But some walls are a lot harder than others if they’re thicker, and ceilings and floors are tough, right?

“But even with half-inch drywall, the reason so many people use stud finders is because a stud is only an inch and a half wide, so if they miss by just a little, they can end up putting a screw into plumbing or electrical that’s fastened to the side of the stud.”

The younger guys started laughing and chuckled,”How did you know? Dude! How did you know? That did happen to him (the boss) just last week!”

Looking a little embarrassed, but still proud and tough, the boss said, “Yes, Sir, I got zapped pretty good; knocked me on my butt, but by the grace of God, I was back to work the next day, and fishin’ the next evening.”

His wife, (who I guessed runs the business’s office, but didn’t seem to know anything about the minor electrical shock) said, ”Honey, I’m gonna get one of these stud finders, but we can keep it in your truck.”  And the boss smiled, and said, “Thanks babe, I love you, too.”  And they walked away with a top of the line Zircon MultiScanner Pro SL wall scanner.

That was many years ago, but even today when people talk to me about finding studs by knocking on the wall, I never imply they should stop doing this.  Using a stud finder should be done in addition to knocking, not instead of knocking! They should work together. Knocking on the wall is a very quick way to find the approximate location of the stud, but a stud sensor shows you the precise location, so you don’t miss by just a little… which could turn out to be a big problem.

It’s human nature for people to be much more receptive to trying something if they are not also being asked to stop something they have been doing for decades. Pros who swear by their Zircon tools on the job still tend to knock and listen.  It’s one more piece of information they can use to help map the wall, and they’ve been doing it for a long, long time.

So go ahead and knock. Use every tool you have to get the job done right: your mind, your knuckles, and your Zircon StudSensor.

Zircon end-users really appreciate that they can call or email us with their questions and quickly get answers from someone who really knows the products very well. One day when I was covering a shift on Zircon’s end-user help desk, I got a call from the crew who were building the Devil’s Slide tunnel.

Entrance to Tunnel – The State of California decided to build 2 tunnels; 1 for northbound traffic, and 1 for southbound traffic.

Entrance to Tunnel – The State of California decided to build 2 tunnels; 1 for northbound traffic, and 1 for southbound traffic.

Each tunnel is approx. 4,200 feet long (about 4/5ths of a mile).  It is a much more challenging application for using the MT6 compared to a concrete and steel building or slab because of the massive amount of rebar. I told Zircon’s engineers that instead of a concrete wall with steel reinforcement, Devil’s Slide Tunnel is more like a steel wall with concrete filler.

I told Zircon’s engineers that instead of a concrete wall with steel reinforcement, Devil’s Slide Tunnel is more like a steel wall with concrete filler.

They were having trouble using the Zircon MT6 to locate rebar in the ceilings of the mechanical room. They needed to miss the rebar to install ventilation. The problem was that the tool seemed to indicate metal everywhere.

Because Devil’s Slide is such a large infrastructure project, and in earthquake country, a massive amount of steel exists compared to a typical concrete wall or floor. I decided to go to the site to see if I could help them. Please see photos and captions for the solution we found.

The 2 tunnels are connected with 10 mechanical rooms, and this is the first location where they needed to use MT6. The California State contract requires that the workers must scan the concrete with a metal scanner such as the MT6 before penetrating it with a fastener to install this ventilation system.

The California State contract requires that the workers must scan the concrete with a metal scanner such as the MT6 before penetrating it with a fastener to install this ventilation system.

Before using any scanner the workers hit rebar about 1/3 of the times they drilled, so they would have to try a new location and patch the unneeded hole, as you can see in this first of ten mechanical rooms. But for mechanical rooms 2 – 10 (using a Zircon MT6) they were about 99% successful in missing the rebar.  Rather than focusing the MT6 to finding metal, instead we looked for the weakest signals, and that system worked.

The next job for the MT6 was in the main tunnels.  Again the workers needed to scan before installing fasteners for Jet Fans, but now they would be high up in a bucket.  The light weight of the MT6 was perfect for performing multiple overhead scans, and they appreciated that it was very quick to scan and determine the weakest magnetic field where they could install a 4 ½ fastener and miss the rebar.

When Zircon was doing research and development on the new x8 metal scanner we took a prototype unit to the crew at Devil’s Slide.  Although the MT6 had been an extremely useful tool that saved them a lot of time and money, they really liked the x8, and they completed the job of installing fasteners to support the jet fans in the tunnel using the x8.  Two features they especially liked on the x8 are 1) the lighted screen, and 2) the ability to select three sensitivity settings.  They suggested it needed a loop for a wrist strap to prevent dropping the x8, and we incorporated it into the final design.

Kurt Stauss at Honeywell

Classroom training started with a video, followed by questions and answers, hands-on training on demonstration walls, and a written applications test.

Zircon has received requests for training at large industrial complexes around the country because the safety departments now require workers to fill out a form certifying that they have scanned the wall, floor or ceiling before workers penetrate these materials, whether they are concrete or drywall.

As these photos show, I conducted classroom and hands-on training for subcontractors who work at a Department of Energy (DOE) site managed by Honeywell, near Kansas City.  Each attendee was trained in the usage of the Zircon MetalliScanner MT6 and the Zircon MultiScanner i500. At the end of the training session, the attendees received a certificate after demonstrating basic proficiency in operating the MT6 and the MultiScanner i500.

The head of the safety department personally researched and tested various brands of metal detectors for concrete and multi-function wall scanners (stud finders) for drywall.  He could have selected different vendors for each category, but Zircon was selected to fulfill both goals based on the performance of the tools, and especially because of their ease of use.

First step in the training was to demonstrate that the MT6 worked in the environment, by locating high voltage lines in conduit in the wall behind me here

Before starting the classroom training, I was asked to demonstrate the MT6 onsite, as this would get the men excited about the capabilities of the MT6. At the onsite location, inside the wall behind me, there were high voltage electrical lines, but they didn’t tell me that.

I was easily able to locate and trace the power lines inside the steel conduit by using the MT6.  Of course, conduit offers some protection in many cases, but if a worker core drills through the wall in that location, it would cut through the conduit (and high voltage lines) like a hot knife through butter! The workers were thoroughly impressed with the performance of the MT6. (They want to get home safe every night)!

The class laughed when one guy commented on how surprised he was that the MT6 works so well, considering how inexpensive it is.

I recently did a similar training at an Intel Chip Fab facility in Arizona and they selected the Zircon MetalliScanner MT6 and the MultiScanner i500.  One comment I hear repeatedly is that they knew about Zircon stud finders, but they had no idea Zircon also made such awesome concrete scanners!

(Note: Cameras are not allowed inside the high security DOE facility, but the photos were sent to me by a DOE staff photographer).
