Product Overview

Featuring new, revolutionary Target Control Level 1 Technology, the Zircon SuperScan M4 advanced wall scanner is tuned to find clean, wood studs while filtering out metallic false positive objects, such as plumbing, conduit, straps, brackets or ducts, hiding beneath surfaces. The LoLevel and MetalliWarning Indicators alert to the presence of dangerous, deep, less dense false positives and metal targets, reducing the chance of accidentally drilling into a piece of metal or plastic pipe. with the addition of AC Scan mode, users can search for hot, unshielded AC voltage. The SuperScan M4 offers 5 distinct detection modes - TC, StudScan, DeepScan, Metal Scan and AC Scan. A 4-mode switch makes it easy to toggle between functions, while the ColorTrip Display conveniently details information. The screen illuminates pale blue in TC mode and locates the center, edges and direction of wood studs, while enabling the user to identify safe-to-drill zones by utilizing the new 'Trust but Verify' technique. When TC mode is off, the tool will perform in StudScan mode indicating both wood and metal studs. DeepScan mode doubles the scanning depth to find wood and metal studs beneath extra layers of drywall or paneling. The dedicated Metal Scan mode helps users identify both ferrous and non-ferrous metals. AC Scan mode enables users to locate and map the wall for live, unshielded AC electricity.
  • New target control mode locates the center, edges and direction of wood studs and not metal, up to 3/4 in. D (19 mm) behind surfaces, identifies safe-to-drill zones between adjacent drywall screws, nails and protector plates
  • StudScan mode locates center, edges and direction of wood and metal studs up to 3/4 in. D (19 mm)
  • Deep scan mode doubles the scan depth of wood and metal studs up to 1-1/2 in. D (38 mm)
  • Metal scan mode locates ferrous metal up to 3 in. D (75 mm) and non-ferrous metal up to 1-1/2 in. D (38 mm)
  • AC scan mode locates live, unshielded AC electrical wiring up to 2 in. D (50 mm)
  • WireWarning detection alerts to live, unshielded AC wires up to 2 in. D (50 mm)
  • LoLevel indicator displays low (weak) signal objects, such as plastic water pipes, while in TC mode
  • Signal strength indicator helps distinguish between shallow and deep targets while in studs can and DeepScan modes
  • MetalliWarning indicator turns on when metal is detected in TC, studs can and DeepScan modes
  • ACT (Auto Correcting Technology) automatically corrects common errors, such as when scanning begins over a stud
  • Low battery indicator for optimum performance (9-Volt battery required, not included)
  • Target spotlight illuminates on screen when target is detected
  • Colortrip display illuminates pale blue in TC mode, green in deepscan mode, blue in metal scan mode and red in AC scan mode and to alert the presence of live AC electricity
  • Spotlite pointer shines an arrow-shaped light on the scanned surface to indicate target location
  • V marker groove enables accurate marking of target location

Enhanced Stud Scanning
The Zircon Brand, SuperScan M4 Stud Finder is an improved model over my older Zircon stud finder. The most significant improvement is the display which can be viewed at an angle, rather than being visible when only viewed straight on. Stud finders are used for finding more than just studs and for learning the presence or absence of other items that may be concealed in walls. It does take practice to become proficient with the use of any stud finder. For me, the most difficult part of learning how to use the SuperScan M4 was relating the user guide to the SuperScan M4. The SuperScan M4 incorporates a multifunction display, as well as colored backgrounds to help the user understand the information being displayed by the SuperScan M4. The SuperScan M4 makes finding solid wooden studs behind drywall very easy to locate using its “Target Control” setting. Termite damaged studs can be more difficult to locate lacking density. I often find magnets, finish nails, a tape measure, and even tapping on a wall can supplement a stud finder to eliminate errors and verify suds and other items concealed behind drywall. However, the SuperScan M4 makes location of a stud easy by giving indication when approaching a stud, when the stud edge is detected and when the stud center is detected with its display by projecting a “Red Arrow” where a notch in the SuperScan M4 is located to make a center mark on the wall. The SuperScan M4 is sensitive to AC powered wires in walls to help prevent accidental penetration with screws and nails that can both be hazardous and expensive to repair. And the SuperScan M4 will locate metal, including “Nail Plates” over studs that are there to prevent the penetration of wires and pipes by nails and screws. The SuperScan M4 helps take the guess work out of locating studs, pipes and wires, however, when necessary, use other means in addition to a stud finder to verify and work safely.

Zircon SuperScan M4 Model #71404
The Zircon SuperScan M4, model #71404, is the latest technology advancement found in a wall scanner “stud finder”. The unit has a low battery indicator, and it uses a 9-volt battery that is not included. This stud finder can be used on 6 different types of surfaces: typical drywall, multi-layer drywall paneling, wood flooring, lath and plaster, and ceramic tile. A nice feature of this unit is that has an ACT (Auto Correcting Technology) circuit that automatically corrects itself if you accidently begin scanning over a stud. The unit features a handy “V” groove to indicate an accurate placement of where the stud is located as well as the lite pointer shines an “arrow-shaped” illumination of the stud location. The stud finder has the ability to locate the edges, center and the direction of wood studs up to 3/4" in depth. In the “Deep Scan” mode, you can scan up to a depth of 1 1/2” for wood and metal studs and in the “Metal Scan” you can scan up to a depth of 3” for ferrous metals (example: black metal pipes, rebar) and 1 1/2" for non-ferrous metal (example: copper waterline pipes). The unit has 5 types of detection modes: Target Control, Stud Scan, Deep Scan, Metal Scan and AC (Alternating Current) Scan to detect unshielded (live electrical wires in a non-metal conduit and non-metal clad) wires that contain live electricity within the wall up to a 2” depth. While in the Target Control mode, the Lo Level™ indicator displays low (weak) signal objects such as plastic water pipes. The manufacturer offers a Limited Lifetime Warranty on the unit. This Zircon stud finding unit was very helpful to me in determining the location of wall studs to hang a very large and heavy mirror. The Zircon SuperScan M4 will help you to better determine where the studs are located and what obstacles are behind the wall and therefore, will help to safeguard you from unforeseen surprises before you drill into the wall.

Great Stud Finder
This Zircon SuperScan M4 Stud Finder can save some time and perhaps some messes. What I mean by “messes” is that which is made by hitting a pipe or wire hidden in a wall. It’s much better than my old scanner, or the magnetic stud finder. It has the ability to find the center of studs, even where the existing screws, nails, or protective plates are. It can find (energized) unshielded electrical wires in most cases. I found that it located insulated copper pipes in a wall. It is very accurate for studs. It has a “LoLevel” indicator to show low signal objects like plastic pipe. It definitely located unistrut pipe hangar behind sheetrock. It also easily found hot electric wires behind sheetrock. I found it difficult to find electric wires 1-1/2 in. behind stucco, lath and insulation board, so I’ll have to confirm what it shows me. It’ll take a little practice to get used to using all the modes and features. This will be a definite “go to” tool for any work on the walls.

Marginal Quality
I’ve had multiple Zircon stud finders over the years. I still have the 5.5 Model & HD800 in my tool drawer. All the walls I’ve used it on were knockdown texture, or orange peel, so fairly smooth. I always remove the battery from the tool during storage (normally for protection should you have a battery leak, but I also heard it’s critical to have a fresh battery in these units, not just one that test good). I thought the HD800 worked pretty good when I got it. However, it appears the units can be somewhat fickle. Not sure if it was a difference in the job, or what. Anyway, I thought it was a good idea to get the “latest and greatest” stud finder. I ran though a couple tests on a wall, and couldn’t really tell much difference between this and the HD800. The M4 appears to be more sensitive to electrical (perhaps too sensitive). I like the new screen which really lights up. However, I was surprised that under the lens of this brand new unit, there is some sort of moisture (perhaps oil?), which makes the unit really look cheap and poor quality. The odd image above the M4 actually is suppose to be there, but I think it looks cheap. When I need to attach a highly loaded fastener to a stud, I’ll take a thin finishing nail, and verify where the center of the stud really is by tapping it in a series of close locations. Due to the poor quality with moisture under the lens, I’m dropping the rating down to 3 stars.

Hi. Thank you for your review of the SuperScan M4 advanced wall scanner, and are happy to hear the scanner is meeting your expectations by finding your studs with accuracy. We’re sorry to hear about the “moisture” under the lens you experienced. It’s difficult to say what may be causing this, but it sounds as though the plastic overlay protection strip may still be on the screen or that the natural oils or moisture from handling may have become entrapped under the lens. We’d be happy to check the tool for you and address this issue. Please call our toll-free support line, found on the Zircon website, during normal business hours Mon. - Fri. 8:00 am to 5:00 pm PST or send us an email. We’re here to help. Thanks. zircon
Super scan M4
[This review was collected as part of a promotion.] I’ve never had great luck with stud finders. Zircon does seem to be fairly accurate and the M4 has some decent capabilities. The a/c wire locator is a big help. We just remodeled a bathroom and knew exactly where everything was located. All the wires were identified along with any metal. It has trouble when there is a bunch of things in one spot. It just goes red screen. The lighted arrow is a nice touch when it detects a stud. Overall, helpful and good to have all locators in one device.

    Performs at 100%
    [This review was collected as part of a promotion.] I read through all of the documents before using. there’s definitely a learning curve to it, although I’ve never used a stud finder before. I prefer this model as it offers 4 different types of finding options so that you can tell where you hit metal, avoid nails in studs, etc. it’s easy to use and easy to read/see where the stud is. Can confirm it’s accuracy.

      Easy to use
      [This review was collected as part of a promotion.] The SuperScan M4 is a great tool to easily identify studs and electrical lines hidden behind walls. I was able to mark the studs for a TV mount quickly and have confidence that I was hitting the center of the stud. Normally I have a few “test holes” trying to find the stud. The M4 made the job quick and easy. Would definitely recommend.

        It works well, but be prepared to do a lot of reading and a lot of practice to get the best out of it. I had a video prepared to attach, but discovered in my final review notes that I was doing things wrong! So, instead I've attached a few pictures because I don't want to mislead you as to how to use this. And that perhaps is the biggest issue with this very nice device: you really have to study the somewhat confusing guide and then practice a lot to get the hang of it. For homeowners, that might be a problem since you may not use it every day. It is easy to forget the best practices. I found it took me 30 minutes of practice to get the best of out of the device. A good example is "TC Mode". Target Control mode focuses on wood, while regular scanning can also find metal and other objects. TC also can give you an indication of a plastic pipe using the LoLevel signal which takes more practice to understand because you have to pay attention to more information on the screen. The way you switch between TC and non-TC mode involves a press-release-long press of the power button. The mode is then indicated by a backlight on the LCD (one of 4 different backlight colors!). This is not a user friendly way to switch modes. I would have preferred a rotary switch to switch between all the various modes, including TC and non-TC modes. For this confusion, and the fact it takes a lot of practice, I'm taking off one star. But at least everything works well once you understand what you are doing! The red arrow that projects on the wall is also very cool. This is by far a much better device than the 30 year old Zircon it replaces. Good job. The electric indicator is much appreciated, although I didn't understand how to use the "all electric" mode. The fact it is basically always on is enough for me. Made in Mexico

        The Zircon Superscon M4 stud finder is a great multi function stud finder. The Zircon M4 stud finder is large item that will be cumbersome in the tool bag but it does fit will in the hand. The M4 has four functions: regular stud finder, deep scan to go through thicker material, metal finder and electrical wire locator. All four functions have their own colored screen. The LCD screen will show the edges of the stud and then the middle of the stud by pointing a red arrow. The same edge finder and arrow will show the location of the metal object and wire. After using trying out the M4 on several different surfaces, it was very accurate and precise.

        This stud finder is a much larger device than others we have used. It works very well in standard configuration (stud behind 1/2" sheet rock) and the metal detection is a significant plus to avoid screws and nails. It works extremely well to detect nails under plaster in order to identify joist or studs. The edge-detect is also a great feature and is enabled by the multi-sensor design. The various advanced features are very confusing - there are four sheets of documentation and not all describe everything - a better manual would be appreciated. Differences in TC and stud scan modes are not clear to me - even switching between them is not obvious. The 4-position slide switch is very 'loose' and it's labeling confusing as well -so a manual or quick reference guide is needed for the occasional user We mapped a test wall with powered wire, stud, sistered up stud, small nail, 1/2" copper line and steel plate. All worked well - the metal plate on the stud, as well as a small finishing nail were seen in TC mode. The copper pipe 1/2" behind the 1/2" sheet rock gave a strong signal, at 1" behind the sheet rock, it was not detected. The AC wire detection is very sensitive -we were not able to determine how far it was behind the sheet rock. We could not detect a 2" PVC pipe or 1/2 PEX, even if it was directly behind the sheet rock. For me, most impressive are the edge detection and metal detection sensitivity. This allows you to scan for even small nails in old wood before running it through a planer, apart from hunting for studs under plaster. We mapped 3 ceilings for nails and identified the joists. It is important to keep it parallel with the studs, otherwise the indicator arrow is off - verifying by moving along the stud is a good way to make sure you have the scanner aligned. Operationally there is one odd effect: keep your second hand away form the scanner, if you place your second hand on the housing (like I did in over-head conditions) the reading will be affected, giving false positions.

        Hi. Thank you for your detailed review of the SuperScan M4 advanced wall scanner. We appreciate your feedback and are happy to know that the M4 works to your satisfaction. We agree that reading the instructions and quick start brochure is key to better understanding the tool’s functionality and always recommend that users become familiar with the tool before beginning any project. You can also find informative instructional videos on the Zircon website to gain a better understanding of TC (Target Control) functionality. To help clarify, the M4 has five scanning modes; TC, StudScan, DeepScan, Metal Scan, and AC Scan. TC and StudScan use the same switch setting but function differently. StudScan detects both wood and metal studs, while TC detects only wood studs and ignores metal. You can distinguish between the two modes by the pale blue backlight on the LCD when in TC mode. The LCD is not backlit in StudScan mode. When set at the TC mode switch position, double click the Power Button to toggle to StudScan mode. AC Scan mode and WireWarning Detection will detect live, unshielded wires up to 2 in. deep. WireWarning detection is on in all stud finding and Metal Scan modes to alert users to the presence of live, unshielded AC electrical wiring and to drill with caution. The dedicated AC Scan mode can be used to locate and map electrical wiring behind the wall. To narrow the results, please refer to the Interactive Calibration method in the instructions. The M4 can alert you to PVC pipe and PEX tubing behind the wall but it’s important to pay particular attention to the mode you are in and to the LoLevel Indicator while in TC mode and the Signal Strength Indicator while in StudScan mode is important. The LoLevel Inidcator will display rapidly cascading bars when the device senses a sustained weak signal, indicating a false positive object (such as a plastic pipe) may be present. The Signal Strength Indicator (uses the same icon as the LoLevel Indicator) will display full signal strength bars when a false positive object is detected.Thank you for mentioning to keep your other hand away from the wall surface and the scanner during calibration and scanning, as this can throw off the tool’s calibration. We have a team of experts that are standing by with any questions or concerns you may have. We’re here to help. Technical and product support services are available during normal business hours Mon.- Fri. 8:00am to 5:00pm PST. Please visit the Zircon website for contact info. Thank you. zircon

        First thing you will notice with this stud finder is that it’s HUGE and at 8 inches tall, it will take up a good amount of room in your toolbox. One Thing I didn’t like about it was that it does not beep when you pass over a stud too quickly. The stud indicator on the screen does show you are passing by a stud but it does not always beep. I do like how the stud indicator on the screen shows you where the true center of the stud is. I don’t work with many metal studs so I probably won’t use that feature. I will use the deep scan feature for finding studs through siding and sheathing outside. Overall, good product, but it’s big.

        This studfinder is Rad! It is the top of the game. It’s also big. I suppose it’s big to hold that big brain. You can see how it compares in size to the older studfinders in my collection. It’s way more capable than my old studfinders as well. The size won’t bother me when I’m using it, but it’s too big to toss into the top tray of one of my tool boxes. This will go into a zipper bag with the instructions so that I can have a refresher course on all of its many functions whenever I need to use it. It automatically finds the center of the stud as well and the notch makes marking a breeze. This tool is great. I highly recommend it.

This unit is amazing in what it can do and how well it does it. I have never seen a stud finder that can do as many functions and do them all so well. I can already see some additional things I can do with the unit above what is shown in the instructions.

        I have owned a few Zircon stud finders over the years. Every time I think I have the "latest and greatest," they develop new technologies that make the old one appear obsolete. I still use my other Zircons for basic projects, but I am now dependent on this one because I have a higher level of confidence when I use it. Instead of simply locating studs, this finder also helps to locate metal and AC wiring simply by moving the main selector switch to the mode you want to use. Another nice feature is that it allows you to focus in on the exact location while re-calibrating when you move the finder back/forth. The only downside is that there are a lot of options. I find that I need the "cheat sheet" to use the finder correctly for my given application. Over time, after I've had a chance to use it several times, I'm sure things will become second nature and I will be able to quickly select the modes that I need. All in all, this is a great stud finder. Hopefully, I won't have to upgrade to another one for several years as this one has all of the bells and whistles to do the job safely and accurately.

        Zircon SuperScan M4 Stud Finder Pros: 9v battery is included, clear instructions, 4 modes of operation, clear display. Cons: None This great stud finder fits perfectly in your hand. The on/off button is ergonomically located for thumb operation (right handed people). The mode switch is located on top of the unit and it is intuitively marked for operation. What is also great about this instrument is that it can operate in four different modes. The default mode locates stud centers with both a display and a red arrow that lights up. In the default mode, the finder will help locate safe to drill locations by identifying nails and protector metal plates. The next mode helps identify all potential targets such as wood, metal, high and low signal strength. Deep scan allows for thicker surfaces. Metal scan identifies metal pipes. AC wire mode identifies live, unshielded wires carrying current. The unit switches easily between all modes and thus covers all potential applications. Highly recommended.

        Very effective, quick, and consistent.--------------------------------------------------------------------------------------------- I’ve used a bunch of detectors, both electronic and magnetic. I’ve found a number that will work well on standard drywall and wood framing. For me, the challenge has been finding studs on plaster and lathe. The plaster in my house is so thick that it is not possible to find a stud with the tapping technique. The only way is to detect the nails which attach the lathe to the studs in order to find the stud. Strong magnets can do that or specialized electronic detectors. I have a homemade magnetic tool with a very strong magnet which works but using it can be slow. I’ve been looking for something faster and easier. Despite claims that they will work, I have NOT found a commercial magnet-based detector that worked on our plaster and lathe even after trying several well known ones. In my experience, for electronic detectors to find the stud underneath plaster and lathe they need a metal detecting function. I own an older electronic detector which will detect the nails under the plaster using the metal function but it has been slower than I like and verification of the detection takes more time than using my own magnetic tool. This Zircon Superscan M4 is definitely faster at finding possible nail locations and either on its own or with my magnetic tool is fairly quick in confirming the stud’s location. This upgraded version is a real improvement over my older electronic detector. That’s also true for detecting more than just studs. For safety reasons you will also want to ensure you don’t drill into electrical wiring and the Superscan M4 is consistent and quick at detecting active AC power in the wall (again, better than my old detector). Repeated tests over the same areas produced the same results while the old detector was not as consistent. You can also use the metal detector to find protection plates added to studs to prevent someone from nailing or drilling into wiring or piping which is threaded through the studs. Even though I’ve purchased two electronic detectors before this, the Superscan M4 is the first electronic stud detector that I’ve been happy with for both drywall and plaster and lathe. I definitely recommend it. TIP: Read the instructions! To get good results you must follow the calibration process for each use and the right scan setting is also important!

        The ZIRCON SUPERSCAN M4 STUD FINDER is a feature-packed device that can steer you from drilling into or cutting wiring and plumbing inside your walls. When scanning a wall with it, it gives very detailed readings on the existence of electrical wiring and plumbing. And, will show you where the center of the stud is. I wasn't able to tell how deep it would penetrate, but it easily read through 5/8" Sheetrock and I'm sure can go even deeper. The size of this device, however, can be challenging. It is about 2" thick at the lower end of the device, which is pretty thick and can make it hard to carry in a tool belt. And, it does not come with batteries, they have to be purchased separately. I have to say, if you're just trying to locate studs, a magnetic stud finder would be more practical and lower cost than this device. But, if you are concerned about wiring and plumbing and don't mind its bulkiness, this device is a useful addition for you.

        Hi. Thank you for your review and purchase of the SuperScan M4. TC and StudScan modes are ideal for up to 3/4" thick drywall, and DeepScan mode is ideal for scanning over drywall up to 1 1/2" thick. While there are a few additional modes and safety features that may seem beyond what a typical stud finder may need, we know these ultimately help users scan wall surfaces more safely and confidently. The size and shape of the tool is the result of extensive research customer feedback during its development but we will take your comments into consideration for future designs..

        WOW! I've used both ordinary, residential stud finders and commercial grade scanners and this one falls right in between those. This thing is ready to go straight out of the package and the battery is included so your ready to go without having to hunt one down or buy one. Maybe a little overkill for just hanging the occasional picture or home decor, but when you want to be sure your dead center on a stud for handing big things like shelves or TV and monitor mounts, then this will get you there. Be sure and read through the instructions thoroughly, so that once you start scanning you understand what the scanner is telling you. It will pick up wood studs, metal studs, live electrical wires and really help eliminate unnecessary holes in the wall or anchors that won't hold. Overall very impressed with this tool and though I have a couple other stud finders, this will be my new "GO TO".

        This stud finder passed every test that I threw at it. With that said, I have some experience with Zircon already, and think it is fair to say that: Holding them flat against the wall, with enough evenly-applied pressure the whole time, is sometimes that hardest part of using Zircon units. With this unit, I was able to test for wood studs, metal, and for AC wires. I did not have an application suitable for a deep scan. Anyway, I verified accuracy in my basement, where the stairs are finished on one side, and studs are exposed on the other. With that said, the entire basement is unfinished, so I could easily verify locations of live A/C wire (from a wall switch or 120V receptacle), I-beam flanges, metal pipes, metal HVAC ducts, studs, or PVC drain pipes. This device protects you, in its ability to differentiate between different material types accurately. Many other stud finders will constantly do a deep scan mode, and can’t differentiate between a stud/electrical/metal pipes. So, many other stud finders will cause you to drill into the wall, because it had a false-positive reading. With this unit, on the other hand, let’s say you are in the stud scan mode. Then, as you pass over live A/C wire, the entire screen changes color and shows you a picture of electric - as a warning. How cool is that? While this isn’t perfect, it is a significant upgrade over my old Zircon. I would recommend it.

        This is a quality tool that solves a lot of problems. It comes with battery and sufficient instructions . My usual way of finding studs to get a sold attachment, is to tap the wall and punch small nail holes until I am satisfied I have found the stud. Does my method work? Yes but it is time consuming and leaves a scarred up wall to repair and repaint. The M4 Studfinder located the center of the stud quickly and precisely. My attached pictures show the M4 locating the stud on the edge of a wall with the exposed stud clearly seen above it. This is a tool that everyone should have in their tool box or on their workbench

        Easy to use and set up and the first wall scanner that I have ever seen that can determine if there is an electrical wire or metal stud or copper or in some older home iron piping. I will say that it cannot find PVC piping or conduit used in whole house vacuum systems. I was able to scan an area where electrical wires were present and it promptly identified. I was also able to identify my wooden studs and then went over to our son’s home and was able to find his metal studs. I would recommend having this around the home if you do anything that involves putting a nail in the wall.

        Hi. Thank you for your review and purchase of the SuperScan M4 advanced wall scanner. We appreciate our customer’s feedback. Target Control technology offers the ability to find wood studs, and not metal, while also being alerted to dangerous false positive targets, like metal or plastic pipes. Paying particular attention to the new LoLevel and MetalliWarning indicators is key. In TC mode, the LoLevel Indicator will flash if it detects objects recessed within the wall such as the PVC pipes or conduit you mentioned. The MetalliWarning Indicator will flash to indicate the presence of metal. We’d love to walk you through it and help answer any questions or concerns you may have.

        This is a good aid in detecting the location of wood and metal studs, screws, nails, and metals. It was not repeatable in detecting wood stud locations in the TC Scan Mode. I had better results with the StudScan, DeepScan Modes. The MetalSan Mode worked quite well in detecting where screws and nails were in the drywall. It even located a copper water pipe that was directly behind the drywall. However it failed to detect the pipe when it was moved further than 1" from the drywall. Where I found the most ambiguous results was in the AC Scan Mode. I knew exactly where the AC wire was and it failed to locate it after many attempts. It would indicate a general area where the wire was, but not repeatedly or accurately. If I held the wire right up against the back of the dry wall the location results were better, but greater than about 1/2" and the results were not useful. (see video)

        Hi. Thank you for your review of the SuperScan M4 advanced wall scanner. We appreciate our customers’ feedback. The TC (Target Control) function works by filtering out metallic objects such as pipes, wires, and sheetrock nail heads so you can zero in on the wooden studs. When in TC mode, the LoLevel Indicator will display when it detects an object recessed in the wall such as the pipe you mentioned. In metal scan mode, a copper pipe (non-ferrous material) may be difficult to detect if it is at the edge of the tool’s scanning range (up to 1 ½ ” deep). In the situation where electrical wires were suspected/known but none were detected, there are different variables that could affect the tool’s accuracy. From your description, it sounds as though you may be working on a test wall which would be difficult for us to determine why you were having trouble detecting AC wires.Please call us directly so that we can help you with tried-and-true techniques for accurate scanning results in all M4 modes. We have a great team of stud finder experts here to help.

        Although the Superscan M4 has 5 modes of operation I'm mostly interested in an accurate stud finder. I have a wall in the basement which is finished (drywall) on one side with the studs and wiring exposed on the other side which was a perfect test location. I measured and marked the exact location of a stud and then used my old stud finder and the Superscan M4 to locate the stud. The Superscan M4 was much more accurate than my old stud finder (see first image). You can either use the notch at the top of the stud finder to actually mark the location or use the spotlight pointer which highlights the target location. The M4 did detect a live AC wire in the wall but it doesn't always reflect the exact location of the wire. I found this to be true in the studscan mode and the AC scan mode. There is a learning curve to using the M4 because the screen is somewhat busy. The unit is pretty big so it is a little difficult to use in confined spaces.

        Hi Jimmy. Thank you of your detailed review of the SuperScan M4 advanced wall scanner. To clarify, the M4 has two AC detection functions: The WireWarning safety feature, which is always on, and the AC scan mode, which has its own switch setting. WireWarning is there to alert you that you are scanning close to live unshielded AC lines. It won’t pinpoint them, but as a safety feature it’s designed to warn you of their presence and to proceed with caution. The AC scan mode will allow you to map an AC line path and location if needed. To help with learning how to use the M4, each tool comes with a printed copy of instructions, a Quick Start guide, and links to how-to videos.

        Zircon M4 Stud Finder. Needs a 9V battery. Not included. This is one of a series of stud finders from M1 to M4 each having the ability to detect more items. The M4 can detect wood studs, hot electrical wiring, metal pipes and what's called a deep scan where you can detect a wood stud that isn't directly behind the drywall. This unit can do a lot but you need to read the instructions to handle all the features. More than just flipping a switch. I use mine mostly for finding wood studs but the ability to find electrical wiring is nice. You can locate the edge of a stud and the center. I also recommend that you down load the product info off the Home Depot site. Much easier to read and store.

        This Zircon Superscan M4 stud finder is a really well-designed tool, and it is very easy to use. It comes with a pretty extensive user fact sheet which describes its use, as well as troubleshooting and construction tips (see picture). The side-mounted power button is very good ergonomically (see picture). It is easy to press to calibrate the stud finder and then hold on while you slowly slide the stud finder over the wall. The display is about 1-1/4 inches by 1-3/4 inches so it is easy to read (see picture). The markings that display are easy to figure out thanks to the user fat sheet provided with the tool (see picture). It will run a long time on the 9 volt battery that the tool uses, and it was a very simple process to inset the battery at the base of the tool (see picture). I did not get any false readings when I used it, so I highly recommend this tool. It is truly an essential item to have to avoid damage to pipes and wires that may be in the wall cavity. The capabilities of this tool go well beyond picture hanging!

        In over 40 years of diy home repair, I’ve had my share of working on all sorts of interior house walls - simple painted drywall to skim-coated drywall to lathe and plaster (current 1896 home). And I’ve tried and used all sorts of scanners to try to know what’s behind the wall before making the incision. This Zircon SuperScan stud finder is pretty sophisticated - it has a bunch of settings for different potential circumstances and its screen provides a lot of information about what’s going on. For a stud finder, it’s a relatively steep learning curve, but once you use it for a while you get to appreciate how talented it is. Given the potential downside risk of damaging a wall in the wrong place or busting a pipe or hitting electric wires, I never rely on on scanning tool. In addition to this excellent Zircon scanner I also use the extremely lo-tech swinging rare-earth ball magnet, knocking with my knuckles and carefully drilling very small holes before I go full bore into a wall.

        Where was this scanner 20 years ago when I ran a nail though a stud that turned out to be a water pipe? This is head and shoulders better than the older models. Besides the basic stud sensor mode, this sensor operates in three additional modes. Those modes are used according to what you are trying to sense. The instructions suggest you scan for studs and other hidden items using a “Trust but Verify” approach. This means you scan the wall just like you would with the old-fashioned Stud Sensor, marking where potential studs are located. You then refine your search by measuring the stud spacing, then further scanning to look for metal (potentially pipes or wires hiding under stud guards) and electrical lines. I used the sensor to on conventional ½” drywall and ½” cement board walls. The sensor was able to successfully detect studs in Target Control mode. Same results with Deep Scan mode. The metal mode successfully detected a copper pipe through the cement board wall. In this case, I had a rough idea where the pipe was, but the sensor zeroed right in on it. Metal mode had no problem showing how wide corner beads were. I also used the AC Scan mode to verify the location of nonmetallic casing AC lines. Worked great there as well. The scanner comes with a couple of sets of instructions with varying levels of detail. Overall, they are all clearly-written. 9V battery not included.

        I had high hopes for this Zircon Superscan M4 Stud Finder as it promotes that deeper detection, boundary accuracy and wire detection. For general purposes, it worked well for finding general studs, without an issue, however it's accuracy on determining edges of studs, detecting deep studs, and detecting wires was iffy. I know this because we have done renovations in the home so I know where general wires, etc are located and it was inaccurate in finding these wires throughout the home - I would estimate about a 50-60% accuracy. I would hesitate to buy this for the special features, but it does work well as a general stud finder and Zircon products have always impressed me, in general.

        Hi. We’re sorry to hear of some of your concerns with the SuperScan M4 and appreciate your assessment of the issues you encountered. Proper calibration and utilizing the appropriate scan depth settings are important factors when considering the wallboard's thickness and the material you are scanning over to help improve the tool’s accuracy. TC and StudScan modes are ideal for 3/4" thick drywall, and DeepScan mode is ideal for scanning over drywall up to 1 1/2" thick. Applying DeepScan mode on the wrong wall thickness can cause the tool to become hypersensitive. In this case, it may be better to switch the tool back to TC/StudScan mode. When scanning in AC scan mode, if you suspect there are electrical wires but are unable to detect any, the wires may be either shielded by metal (i.e., conduit, braided wire, or metallic wall covering), lie deeper than 2 in. from the surface, or may not be live. If shielded by metal, use Metal scan mode to locate the metal covered wires. Please note the WireWarning detection feature is always on in TC, StudScan, DeepScan, and Metal Scan modes to alert you to the presence of live AC electricity while scanning. Feel free to contact us so we can walk you through it together. Technical and product support services are available free of charge during normal business hours Mon. thru Fri. 8:00am to 5:00pm PST.

        After using the simple magnetic stud finders, I didn't think I needed a better one, but I was mistaken. I love this tool! It has 5 modes: Target Control, StudScan, DeepScan, Metal Scan, and AC Scan. It can detect the stud centers, stud edges, stud directions, deep studs, studs with metal, and wiring. You decide what you are looking for and use the appropriate mode and its options. There are plenty of hints and instructions included. I love the safety feature of WireWarning Detection to help prevent drilling into a live, unshielded wire up to 2" deep. It needs a 9V battery which is not included in the package. It is easy to grip, and has an easy to see display. I like that it shines an arrow image on the wall to show exactly where to make my mark. It is simple to use - hold in power button for about 2 seconds to calibrate then after the beep, just move it across your wall slowly while still holding the power button in. When it finds the target, it will beep, the arrow will light up, and an image of the arrow will appear on your wall. This sensor is designed in the USA and assembled in Mexico. It has a limited lifetime warranty.
