The Best Stud Finder Options And Reviews For 2021 and Beyond

Best Stud finders are handy for finding the studs located behind walls. Though it may work, to some extent, the ‘tap and guess’ technique will generally leave your wall or ceiling with so many unnecessary holes. A stud finder will save you lots of time by detecting the location of studs. Having a reliable stud finder, therefore, saves you not only the agony of making several wrong guesses, but it also eliminates the need to repaint your wall, which results from the use of traditional methods. 

You have several options of stud finders to choose from. However, there is no one-size-fits-all stud finder for the needs of all individuals. Here, we break down for you a list of the most reliable stud finders in various situations, complete with their special features, as well as pros and cons. Stud finders are largely either magnetic or electronic.

Magnetic stud finders have a magnet, which they use to find the screws that fasten your drywall in the right place. However, they are incapable of sensing the real studs, hence finding the exact centre involves some guesswork. They are also cheaper compared to electronic stud finders which come with active sensors, though they are not as many. 

On the other hand, electronic stud finders sense variances in wall density to locate studs. They are normally powered by batteries. Most of them can sense metal or wood studs and a number of them come with AC power sensors. The simplest of the electronic models can help in locating stud edges while some reveal the full stud width. They are more costly compared to magnetic models, but not exorbitantly so. You can still get some of the best electronic models at a price lower than $25.

The fast-paced evolution in modern technology now makes it possible to find apps for both android and iPhone smartphones. Such apps utilize the phone’s magnetometer (the same sensor which powers the compass) to sense screws or metal nails beneath the drywall. The screws and nails are likely to be within the stud that you are trying to find. However, these apps are incapable of gauging wall density or sensing real wooden studs.

Stud finders are not the only tools capable of detecting objects that are underneath the wall surface. Wall scanners are also known to perform the same function quite well. Professionals mostly use the radar-like implements to find out what lies beyond the walls, other than studs.

Some individuals still use a hammer or knuckle to find studs. As much as there some are people who are good in using this method, it is rather unreliable when it comes to sensing studs in your drywall. 

Top Tips in the Usage of Stud Finders

  • Ensure your hands are off the wall to forestall any form of interference.
  • Ensure you know whether your type of stud finder requires calibration. If yes, how is it done?
  • While doing the detection, ensure your stud finder remains flat against the wall.
  • Use a combination of a crossline laser and a stud finder to mark the whole stud length or to hit a similar height across several studs. 
  • To ensure the optimum accuracy, mark your location from many directions unless you are making use of a full-stud sensor. If you don’t want to mark straight on the paint, a bit of a painter’s tape can serve you well. 
  • Studs are normally 24 inches away from each other (for ceilings) and 16 inches apart (for walls). Whenever you struggle to find one, just get a better reading on a different part of the wall and take the measurement. 
  • Stud finders can also do a great job in locating joists on ceilings. 
  • Finding studs in any plaster wall can be a bit tricky. Many stud finders are unreliable on lathe and plaster. You are better off using metal detectors instead. 
  • For electronic stud finders, it is prudent to always have a spare set of batteries with you. 

Below are some of our top recommendations. 

Best Magnetic Stud Finder

CH Hanson 03040 Magnetic Stud Finder ($14.99)

best stud finderThe magnetic stud finders are more old-fashioned compared to the more advanced modern types. Regardless of their simplicity, the magnetic finders are a good option for anyone who is out for something that doesn’t need batteries to work. 

The CH Hanson 03040 is a good example of an effective magnetic stud finder. Its built-in magnet is automatically attracted to the screws and nails that keep the home’s frame in place, giving you a hint regarding the location of the studs behind the drywall.

Special Features 

  • Its body comes with a two-way level which makes it easy to hang the gadget from a metallic stud to improve the accuracy of levelling surfaces such as walls. 
  • The pointed arrow located on the bottom appropriately marks the safe spot for nails and screws. Hence, it makes it unnecessary to use trial and error when hanging frames, pictures and other things on the walls. 
  • The CH Hanson 03040 is fitted with more powerful magnets as compared to several of its challengers. The potent rare earth magnets effortlessly locate fasteners and metal studs without any requirement for power. 
  • It also comes with a spinning bubble level, which is a useful feature on any magnetic model. 

Due to its inability to electronically detect the centre and sides, it is vital to attain the stud finder level to easily track the stud. However, this assumes that the stud is also straight, which is not always the case. 


  • Powerful magnets
  • Tried-and-true easy operation 
  • Senses wood stud fasteners and detects ferrous metal studs
  • Reasonably priced
  • Incorporated spinning bubble level 


Incapable of sensing centre and wood studs

best stud finderA budget stud finder sounds like a pocket-friendly option for your random weekend home project. It is, however, advisable to tread carefully, because several budget alternatives lack the desirable accuracy needed to dependably drill into your walls. Generally, most budget options come with basics but lack any additional detecting abilities. 

Zircon Pro StudSensor A100 offers you the basic metal and wood stud detection at a pocket-friendly price. Nevertheless, this finder comes with several handy features that will interest you.

Best Stud Finder for Metals

Zircon MetalliScanner m40 ($41.31)

best stud finderMetal support material can be tricky to detect when using stud finders that are typically standardised for wood studs. Not even the magnetic finders can detect all kinds of metal since some metals lack magnetic characteristics. The Zircon MetalliScanner M40 is built to sense a wide range of metal objects and supports behind ceilings, walls and floors. 

The MetalliScanner senses both magnetic (ferrous) and non-magnetic (non-ferrous) metals behind several non-metal floors, walls and ceilings. Other than metal support structures and studs, the finder is great for locating smaller items such as nails and screws that might be embedded deeply into the wall (up to 4-inches deep). The blue coil will change, as the finder moves, to show the exact location of any detected object. 

Finding studs embedded in a plaster wall is never an easy task. Magnetic and electronic finders are normally not reliable for such a task. The MetalliScanner M40 is technically more of a metal detector than a stud finder. Hence, it can detect metal in a wide range of materials, plaster included. The lathe is known to have more nails than just those found on the stud. Hence, it takes a good stud finder to perform the task. 


  • Detects metals that are deeper compared to magnetic models 
  • More accurate in finding studs on plaster than most conventional stud finders.
  • Comes with a pinpoint scan which is useful in finding screw and nails more easily. 


  • Not the best option if your plaster wall has wire mesh.
  • To get the most accurate outcomes, you have to run it several times both vertically and horizontally. 
  • Metal pipes, as well as other metallic objects, might throw your search off-track
