The best stud finder can be used in construction or renovation work. As its name suggests, the tool is useful to detect metals and non-ferrous metal behind a wall. These metals can include regular water pipes, live AC wires, rebar metals or even non-ferrous metals such as copper pipes, used for central heating water circulation.
There are two main technologies used in these tools. They detect these metals and non-metals using magnetic or electronic methods. Of course, powerful magnets inside some stud finders make the job easy and quick. An electronic stud finder can be a precise tool. Based on changes in dielectric constant, the stud finder can indicate the presence of a stud. When the readings change to a lower frequency, it is a sign that a stud has been detected.

Features to consider in Good Stud Finders
There are multiple stud finders on the market. It is why those new to the field might even have a hard time deciding on which product to purchase. Regardless if the stud finder is used by a professional or simply used at home, it should be able to offer reliable results.
Having the ability to detect metals and wires is a must. But the best stud finders can even detect wood studs. All of these capabilities actually come with considerable savings when it compared to tearing down walls to find studs.
The accuracy of the sensor’s readings is different from product to product. Of course, the best accuracy is when the studs are not too deep inside the wall. This is why most products measure the right distance in millimeters. Under normal circumstances, wood studs are not as easy to detect further inside the wall as metal studs.
An LCD display is the quickest way a stud finder can signal a stud. Having intensity readings on electronic stud finders can help pinpoint the exact center point of the stud on the LCD screen. The following stud finders use various extra features for accurate results.

The handheld device is one of the choices construction workers have when dealing with existing buildings. Instead of endangering themselves drilling holes in the wrong place, they can use the Drtulz Stud Finder.
The design of the device allows it to be considered as modern, even in a category which doesn’t need too much innovation at this point. Dominated by a backlit LCD screen, the device can also be used in low light conditions. The readings are very simple on the screen and they use a bar system to indicate whenever a stud is found. At the same time, there is an audio beep which alerts the user of the existence of a stud.
A single button allows the user to select the type of stud to scan for. From metal to AC wires, it can detect all studs. The stud finder is powered by a regular 9V battery. There is a battery indicator on the screen as well, but users should only replace it after months of use.

Turning the tool off is not necessarily user-based as a result. After 60 seconds of inactivity, the stud finder powers off to protect battery life.
The multifunction stud finder is made from ABS plastic. This type of plastic is durable and reliable. Apart from the models which come with extra rubber, it is considered to be made to a high standard of durability. It also comes with a weight of just above 100g. This means that those into construction can use it multiple times per day with no fatigue.
In terms of performance, the stud finder is as versatile as users can hope for. Metals and wood can be scanned at depths of up to 19mm and sometimes even up to 38mm. A special deep mode is also available which allows users to detect metals up to 60mm deep.
Using the bar indicator on the screen, users can also have a better understanding of the edges and the center point of the stud. This is where they have the freedom to scan around and to indicate the center point of the stud which is also accompanied by a beep.
Unlike many similar products, the stud finder also comes with auto calibration. Calibration is done by scanning a plain wall with no nails or no studs.
Based on its auto calibration and modern display, the stud finder is one of the few options which come with a short learning curve.
- A large backlit LCD screen
- Beeps at the center of a stud
- Comes with a deep scan function
- Made with auto calibration
- Long-lasting battery included
- Inconsistent results with wood studs on deep scan
With decades of manufacturing experience, Zircon has managed to create one of the most robust wall scanners on the market. But there is more to its rugged design than meets the eye. It is one of the few stud finders which come with an included marking tool. The marking tool has its own button. Users need to push down the button in order to release the marking tool.
Another important physical feature comes with a bright display. It is one of the brightest in its class. While this may not be a concern for many users, others prefer such displays, especially when working on hallways or any other areas with low visibility.
Although the product comes with easy operation, some users might still need extra information on the stud finder. It is why Zircon offers good customer support as well. They can also point out the best ways to use the tool for accurate readings.
There are 4 convenient modes to switch between by the user. There is a unique floating head design on the stud finder. It has been made this way to improve accuracy, especially over uneven surfaces such as brick walls.
Most detected studs can be metals. But the stud finder also finds non-metal studs such as copper. Readings are accurate and they can also detect rebar. Furthermore, the powerful scanner also works through plaster.
Its StudScan mode works with scans of up to 19mm. In fact, this is its most popular model. It is why the manufacturer recommends the first scans to be made in this mode. Its DeepScan mode works with greater depths of up to 38mm. Of course, readings at this depth are not as constant. It is why the stud finder also comes with a warning light whenever a wire has been detected.
A dedicated Metal Scan Mode is also available. As its name suggests, it is programmed to scan metals. It works with copper scans within ½ in depth and with metal scans at a depth of up to 3 inches. This mode is particularly useful to tell if the stud is made from metal or if it’s made from wood. Wiring can also be detected using the scanner. All wires at a depth of up to 2 inches can be detected simply by choosing the AC Scan Mode.
With dedicated scanning modes, users can consider the stud finder to differentiate wood studs from metal studs.
- Made with a bright LCD screen
- Designed with a floating head
- Detects AC wires up to 51mm

From a visual stud representation to an actionable design with just a few buttons, the tool manages to base itself as a simple alternative. There is a simple bar indicator showing the edges and the center point of the stud. However, one of the main advantages of the stud finder comes with its rubberized case. This means that it can be a tool to consider for busy professionals who need the improve grip for constant readings.
Apart from an anti-slip design, the stud finder features a backlit LCD screen. All the information relevant to the user is displayed here. From battery life information to the type of scanning mode, the screen is where users need to look at to get the latest on the readings. There is a speaker underneath the screen. Its role is to emit beeps whenever a center point of a stud has been detected.
The screen is among the best in its class. This is not necessarily due to its graphics but rather due to the displayed information. It shows all detection modes, automatic calibration information, signal strength information as well as battery information. Auto calibration is even easier to go through than actual scanning. It only requires scanning a wall free of nails or other distractions. Of course, calibration should never be made over freshly-painted areas. When calibration, users should also not place the stud finder directly next to a stud. The good news is that when the calibration is not done right, there is a flashing sign appearing in the middle of the screen.
The stud finder is very useful in construction, decoration or even furniture installation. Drilling positions need to be safe and free from studs. Drilling positions also need to be free of wires for safety reasons.
The stud scanner does a good job with wooden studs up to 19mm. A deep mode is also available but the results might not be as quick up to 38mm. AC scan and metal scan can go even further up to 60mm. With a weight of 146 grams, the stud finder is not the lightest option on the market. However, the extra weight comes from the rubberized ABS case. Some users even prefer a heavier stud finder for a more professional feel.
Made to resist light shocks with its rubber casing, the stud finder is mainly made for heavy use.

- No marking tool
With an ergonomic grip, the stud finder comes with its own visual identity. It is easy to hold with a single hand and it comes with low weight as well. The ergonomic grip might not be enough to convince new buyers, but there is a lot more to it than its simple glass-shaped body.
Made with a rubberized grip, the stud finder is surely not slipping away from the hands. It is a solution which can even save money with possible future repairs. At the same time, it also saves money with the possible damage from drilling done in the wrong place.
There is a backlit monitor on the upper half of the stud finder. All the information displayed here is a result of the user input through the side buttons or a result of scanning and auto calibration. The power button on the left side needs to be pressed in order to power on the screen. A target indicator bar is immediately visible in the middle of the screen. The bar is similar to what is seen in most stud finders and it indicates the edges and the center point of various studs. There is a front speaker as well. As expected, it is this speaker which beeps whenever a stud is discovered.
With the standard 4 scanning modes, the stud finder detects most studs. Wooden beams and studs are detected at a depth of up to 1.2 inches. Metal and AC wires can be detected at a depth of up to 1.57 inches. A deep mode is available as well with results up to 1.77 inches deep. 85 to 240 V current can be detected at depths of up to 1.77 inches.
The good news is that all of these modes are used in the same simple way. First of all, a 9V battery needs to be placed in the stud finder. For the best results, the product also needs to be calibrated. This is done by placing it against a wall while holding the power button for up to 2 seconds. Detecting a stud is similar as well. Holding the power button, users can simply move the scanner along the wall until a beeping sound signal the existence of a stud.
With a rubberized ergonomic grip, the stud finder scans all studs and its leading performance is seen with deeper AC current wires.
- Made with an ergonomic grip
- Comes with 4 scanning modes
- Built-in speaker for stud beeping
- Detects electrical wires up to 2.36 inches

With an attractive compact design, the Vivreal Stud Finder is easy to hold. It does not have a unique or memorable look but its aim is utilitarian and it is here that it does its job well. A single button for mode selection means there is no time wasted on the construction site looking for complicated settings. At the same time, the backlit LCD screen means that all the stud reading information is easy to read.
There are only two buttons for the user on the stud finder. One is made for the power mode and the other is made for the scanning modes. Both are used with every scan. While the power button is held in place when making readings, the scan mode button only changed position before an actual scan.
There are a few debatable design drawbacks to consider as well. One of them is the simple plastic casing which might not survive a fall from a higher point. Another possible issue comes with the fact that it doesn’t have a marking tool included. So whenever a stud is discovered, users simply need to ensure they actually have a pencil to mark its spot.
The 4-in-1 design means no other tools are needed for stud detection. It means that construction workers or simple residents can use it with precision to detect the location of a stud and a point where drilling is excluded.
Automatic calibration is needed whenever the tool is turned on. As with most stud finder, the calibration is actually easy to achieve. Most importantly, users also need to know that its calibration also plays a role in accuracy. With all the features needed to detect metals, non-metals, wood, and current wires, the stud finder is reliable in most situations.
Based on accurate results up to 51mm, the stud finder can be a solution for professionals or homeowners.
- Operated with just two buttons

Residents may encounter live wires in the wall or other metals which may hinder their drill or even represent a safety risk. For this purpose, using the stud finder can be useful, even if just mounting a couple of shelves.
Its simple design is mainly based on the versatility of its 4 scan modes which are fairly represented on a small digital display. There is an indication bar on the screen for every stud. Its center point is represented by the highest bar. Its edges are represented by the shortest bars to the left and to the right. This is one of the simplest graphic stud representations seen on built-in displays.
Of course, the display also comes with extra pictograms to identify the scanning mode. This scanning mode can look for wires, metals, or even copper and aluminum at a depth of up to 1.18 inches. A beeping alert is also available with the stud finder. The tool only beeps on the center of the stud.
The stud finder is reliable. However, in order to get the best readings, it is recommended to take the process seriously. One common mistake is simply moving too fast. Users should take their time during the scan. Another mistake comes with wet walls where the paint is not dried. Gypsum surfaces are also known to create interferences for the best accuracy. Another top tip comes with uneven surfaces. Scanning these surfaces should be made behind cardboard.
With an intuitive stud bar indicator, the scanner is even recommended for its short learning curve.
- Made with a unique stud bar indicator
- Detects metals down to 60mm
- Made to detect wood, aluminum, and copper
- Not best for freshly-painted walls
With one of the smallest designs in its class, an affordable stud finder is a worthy option in the box of tools of any home. It even comes with a digital display.

Never scanning for studs should not be a limiting factor. Most stud finders come with a short learning curve and they can be mastered within minutes.
Can I leave the battery inside my stud finder?
If the stud finder is used on a regular basis, the battery can remain inside. To prevent oxidation in the long term, it is recommended to remove the battery if the scanner is not used too often.
I’ve just painted over a wall but I can scan for studs, what can I do?
Those who have a freshly-painted wall might want to drill their holes back in position, which might be the case with bookshelves or TV stands. It is recommended to leave the wall dry completely before making a scan.
Do I need to scan each time I use the drill?
For safety purposes, a stud finder needs to be used before drilling. Unless the homeowner knows where the studs are, this is a must-do.
Guide to Buying the Best Stud Finder
Choosing the best stud finder is not complicated. There are not too many designs to consider which might make the entire process much shorter than expected. Here is what needs to be taken into consideration.
A digital display is a norm for the best stud finders. It comes with all the essential information needed to find various studs. It even signals the edges of the studs for maximum precision. An added screen can also show the current scan mode.
Scan modes vary from general to specific AC wiring, wood or deep scanning. It is recommended to start scanning with the general mode which works with the best accuracy. Deep scanning might require going over a stud a few times.
Audible warnings are not included in all stud finders. However, they can be a real aid when it comes to determining the exact center point of a stud. Users need to remember to mark this spot.
Calibration is either user-defined or software-defined. Most stud finders come with user-defined calibration. Rarer products offer constant auto calibration functionality which might prove better for those making multiple readings per day even through plaster.
Ability to detect non-metals
Copper and aluminum are also seen inside walls. They might not be detected by the regular metal scanning mode of an electronic stud finder. At the same time, they can be real hazards when facing a drill. Copper pipes can be used for central heating and avoiding water damage is simply made by selecting the right stud finder and activating the right scanning mode.
Stud finders are used by professionals or by simple home residents. They are mostly reliable. But in order to get the most accurate results, the stud finders also need to be used correctly. Most problems occur with gypsum walls or with walls which have not completely dried after painting.
Uneven surfaces are another obstacle in the way of accurate results. Furthermore, it is important to know that some of the best stud finders on the market can overcome most of these problems if used correctly.
Since most stud finders come with user-based calibration, it is important to go through this process before every scan. For this reason, users can simply choose the right wall for calibration. The calibration process should not see the stud finder placed directly on top of a stud. The wall where calibration is being carried out should also be free from nails or other obstacles.
With proper calibration and reliable batteries, each stud finder is able to work with a high degree of accuracy. Most manufacturers also recommend slow movements during the scanning process. Without rushing every scan, slow movements can detect metals, wood, and AC wires up to a few inches deep. After a stud is discovered, a built-in marking tool or a pencil can be used to mark its position. Multiple scans can be made in the case of wires of piping to find the exact line they follow inside a wall.
